909 BVA cases. 30.3% granted. 38.7% denied. 31.0% remanded. And in 86 of those cases the Board cited DC 5242 (degenerative arthritis of the spine), in 61 it cited DC 5243 (intervertebral disc syndrome), and in only 26 it cited DC 5238 (spinal stenosis specifically as its own diagnostic code). The same condition. The same anatomy. Three different doors into the rating schedule, and the door the Board walks through usually decides what the case is worth.
This is the quiet thing about spinal stenosis claims that I want to walk through in this post. The diagnosis is durable: most veterans who reach the Board with a stenosis claim do have stenosis confirmed on imaging. The connection theory is usually direct service connection through documented in-service back complaints or post-service degeneration. The rating schedule is the general formula at 38 CFR § 4.71a that governs all spine claims. But the diagnostic code citation, the range-of-motion measurement methodology, and the question of whether to rate under the general formula or the IVDS incapacitating-episodes alternative are where the real money sits. The Board's coding choice is rarely random, but it's also rarely transparent to the veteran. Let me show you what 909 cases tell me about how this claim actually moves.
TL;DR
- 909 spinal stenosis cases at the BVA. Granted 30.3% (275), denied 38.7% (352), remanded 31.0% (282). The three-way split is unusually balanced: no single outcome dominates.
- Direct service connection accounts for 625 of 747 cases with a connection type, 68.7% of the pool. Direct grants at 36.2%.
- The diagnostic-code distribution is the underreported finding: DC 5242 (86 cases), DC 5243 (61), DC 5237 (26), DC 5238 (26, stenosis-specific), DC 5293 (14). The Board reads the medical record and codes downstream.
- 40% is the modal granted rating (67 cases). That tier requires forward flexion ≤ 30 degrees or favorable ankylosis under the General Rating Formula.
- 59.5% of C&P exams in this subset were flagged inadequate, above the 52% dataset average. Correia v. McDonald violations are part of the story.
- Strong nexus grants at 91.8%. Weak nexus grants at 0.7%. The cliff is the same here as everywhere else.
909 Cases: Stenosis in the Back-Cluster
The first thing to understand about spinal stenosis claims is that they don't exist in isolation. "Back" claims at the BVA are a cluster of overlapping conditions: lumbar strain, degenerative disc disease, degenerative arthritis of the spine, intervertebral disc syndrome, spinal stenosis, radiculopathy, and a long tail of more specific diagnoses. The same veteran often has multiple of these in the chart, and the Board has to decide which diagnostic code primarily applies and which others are either subsumed or rated separately.
In my dataset of 101,518 condition records drawn from 49,876 Board decisions, the back-cluster is enormous. Lumbar spine claims as a category run into the thousands. Spinal stenosis specifically, defined as cases where stenosis is the named condition or the primary diagnostic code in the appeal, comes to 909 cases.
The outcome split is balanced enough that you have to read it twice:
- Granted: 275 (30.3%)
- Denied: 352 (38.7%)
- Remanded: 282 (31.0%)
That balance is unusual. Most condition cornerstones I've analyzed lean one direction or another. Chronic fatigue is 58% denied. Sinusitis is 46% denied. PTSD is grant-leaning. Spinal stenosis sits roughly three-way evenly distributed, which tells me the Board isn't applying a structural denial pattern here. The cases are getting decided on their individual evidentiary pictures, and the picture splits roughly evenly between grants, denials, and "send it back for more development."
The 31% remand rate is consistent with the wider back-cluster's tendency to bounce on inadequate range-of-motion testing. I'll get to Correia and the ROM measurement issues below, because they're a big part of why so many of these cases come back.
DC 5242 vs 5243 vs 5238: Why the Coding Matters
Diagnostic-code distribution in the stenosis subset
Here's the diagnostic-code distribution in my 909-case subset:
- DC 5242 (degenerative arthritis of the spine): 86 cases
- DC 5243 (intervertebral disc syndrome): 61
- DC 5242-5243 combined: 16
- DC 5237 (lumbosacral or cervical strain): 26
- DC 5238 (spinal stenosis specifically): 26
- DC 5293 (legacy IVDS code from before the 2003 revision): 14
- A long tail of other codes: the remainder
Notice that the stenosis-specific code, DC 5238, applies in only 26 of 909 cases. That's roughly 3 percent of the pool. The most-cited code in stenosis claims is the degenerative arthritis code, DC 5242, with 86 cases, over three times as many.
The reason is that most spinal stenosis at the BVA presents alongside degenerative arthritis or disc disease. The stenosis is a finding on imaging, but the underlying pathology that drives the impairment is degenerative. The Board picks the code that best fits the dominant pathology in the medical record, and degenerative arthritis is more often the dominant clinical picture than pure stenosis.
Why the choice matters for rating
For rating purposes under 38 CFR § 4.71a, this matters less than it sounds. DC 5238, DC 5242, and DC 5237 (strain) all use the same General Rating Formula for Diseases and Injuries of the Spine. The rating tiers (10%, 20%, 40%, 50%, 100%) apply identically across these codes.
DC 5243 (IVDS), on the other hand, has an alternative rating pathway: the Plus Formula for Rating Intervertebral Disc Syndrome Based on Incapacitating Episodes. The IVDS code can be rated either under the General Rating Formula OR under the incapacitating-episodes formula, whichever yields the higher rating. That's the only diagnostic code in the back-cluster where the veteran gets a structural choice between rating frameworks.
The practical implication: when a stenosis claim presents with documented disc involvement (herniation, protrusion, neural impingement from disc material), being coded under DC 5243 opens a rating path through incapacitating episodes that the other codes don't have. For a veteran whose stenosis flares with episodic incapacitation but whose range-of-motion measurements are inconsistent, the IVDS pathway can produce a higher rating than the General Rating Formula would.
The 61 DC 5243 cases in my dataset reflect that some appellants are routed through this alternative. Whether that routing is optimal in any individual case depends on the specific imaging findings, the symptom pattern, and how the Board chooses to characterize the dominant pathology.
What I see in the data is that the diagnostic-code choice is rarely the explicit fight in the BVA decision. The Board codes the case, applies the rating schedule, and the veteran often doesn't realize there was an alternative pathway. That's worth knowing in advance.
The Range-of-Motion Ladder
The General Rating Formula for Diseases and Injuries of the Spine, under 38 CFR § 4.71a, structures the entire back-cluster rating system around two measurements: combined range of motion of the thoracolumbar spine and the presence or absence of ankylosis.
The tiers are:
- 10%: Forward flexion of the thoracolumbar spine greater than 60 degrees but not greater than 85 degrees, OR combined range of motion of the thoracolumbar spine greater than 120 degrees but not greater than 235 degrees, OR muscle spasm, guarding, or localized tenderness not resulting in abnormal gait or abnormal spinal contour, OR vertebral body fracture with loss of 50 percent or more of the height
- 20%: Forward flexion greater than 30 degrees but not greater than 60 degrees, OR combined range of motion not greater than 120 degrees, OR muscle spasm or guarding severe enough to result in an abnormal gait or abnormal spinal contour such as scoliosis, reversed lordosis, or abnormal kyphosis
- 40%: Forward flexion of the thoracolumbar spine 30 degrees or less, OR favorable ankylosis of the entire thoracolumbar spine
- 50%: Unfavorable ankylosis of the entire thoracolumbar spine
- 100%: Unfavorable ankylosis of the entire spine (cervical and thoracolumbar combined)
The forward-flexion measurement is the most-cited single variable in the rating decisions I read. A measured flexion of 31 degrees lands the case at 20%. A measured flexion of 30 degrees lands it at 40%. That one-degree threshold matters enormously, and it's why C&P examiners have to be careful with how they measure.
The rating distribution among granted cases in my dataset:
- 10%: 13 cases
- 20%: 42 cases
- 30%: 15 cases (this is rare: 30% isn't a standard tier on the General Rating Formula and usually reflects a different rating framework being applied)
- 40%: 67 cases (the modal grant tier)
- 50%: 10 cases
- 100%: 2 cases
40% is the modal grant, and that makes sense. The veterans who appeal to the BVA for spinal stenosis are usually the ones whose forward-flexion measurements are restricted enough to support 40% but who weren't awarded that tier at the regional office. Once the Board is convinced of the measurement, the 40% tier is the natural landing zone.
The 100% schedular rating for spine claims requires unfavorable ankylosis of the entire spine, cervical plus thoracolumbar combined. That's a rare clinical finding. Two cases in the dataset reached schedular 100%. For most veterans whose spinal impairment is functionally totalizing, the path to 100% runs through TDIU (total disability based on individual unemployability) rather than schedular spine ratings.
Correia v. McDonald in Practice (Why the C&P Inadequacy Is 59.5%)
The C&P adequacy rate for spinal stenosis in my dataset is 40.5% adequate, 59.5% inadequate. The 52% inadequacy benchmark across all conditions puts spinal stenosis 7.5 points above average. This isn't an extreme outlier, but it's elevated, and the reason has a name: Correia.
In Correia v. McDonald (2016), the U.S. Court of Appeals for Veterans Claims held that a C&P examination of joint range of motion is inadequate unless the examiner measures the joint in (a) active motion, (b) passive motion, (c) weight-bearing, and (d) non-weight-bearing, and also addresses both flare-ups and functional loss following repetitive use. The decision interpreted 38 CFR § 4.59 and § 4.40, which require the examiner to consider the functional limitation as it presents during periods of flare-up, not just the stable baseline.
The Correia requirements apply to all musculoskeletal exams, including the thoracolumbar spine. An examiner who measures forward flexion only at the moment of the exam, with the veteran rested and cooperative, and who doesn't address how flexion changes after repetitive motion or during a flare-up, has produced an inadequate exam under Correia.
The Board, post-Correia, has been consistent about flagging exams that don't address all four measurement positions and the functional loss factors. Those exams come back as inadequate, and the cases get remanded for a new exam.
In the spinal stenosis subset, 59.5% inadequacy is consistent with the broader post-Correia pattern across spine claims. The C&P examiners who do back exams routinely are mostly orthopedic or general medical providers. Many of them produce reports that capture the baseline ROM well but skip the active/passive/weight-bearing distinction or fail to address flare-ups in measurable terms. The Board sees the gap, flags the report, and sends it back.
For veterans, the practical impact is the 31% remand rate. Most of those remands aren't denials in disguise. They're "the file isn't complete enough to decide on; the exam needs to address Correia factors; the case needs a new C&P that does it right." On the second exam, when the Correia factors are properly addressed, many of those cases come back as grants at the appropriate tier.
If you're filing or appealing a stenosis claim and your C&P exam report doesn't explicitly address active, passive, weight-bearing, and non-weight-bearing ROM, and doesn't quantify the functional loss during flare-ups, that report is vulnerable under Correia. A supplemental exam request or a private orthopedic evaluation that captures the missing measurements can be the difference between a remand cycle and a clean grant.
Why 40% Is the Modal Outcome
The 67 cases granted at 40% are worth understanding as a cohort. These are the cases where the Board found forward flexion of 30 degrees or less, or favorable ankylosis of the entire thoracolumbar spine. Each of those findings represents a significant functional limitation that the rating schedule recognizes as substantial.
Why does this cluster around 40% rather than spreading more evenly across the tiers?
One reason is the structure of the General Rating Formula itself. The jump from 20% to 40% is a single threshold: forward flexion crossing the 30-degree line, or favorable ankylosis becoming established. There's no 30% tier in the spine schedule for most diagnostic codes. (The 30% rating in the rating distribution above reflects a small number of cases rated under different frameworks, including some pre-2003 IVDS rating decisions that are still in effect.)
Another reason is selection. Veterans whose flexion measurements are clearly in the 30-60 degree range usually receive a 20% rating at the regional office and don't necessarily appeal. Veterans whose flexion measurements are clearly above 60 degrees usually receive 10% and don't usually appeal for the schedular increase. The cases that do reach the BVA are often the ones where the measurements are inconsistent, contested, or close to a threshold. Once the Board resolves the measurement, the 40% door is more often the right one.
A third reason is functional. By the time a veteran's stenosis is causing forward-flexion measurements at or below 30 degrees, the condition is significantly impairing. That impairment level is what the rating schedule is designed to recognize, and the 40% tier is where that recognition lives.
For a single veteran in 2026, the dollar values matter:
- 20%: $346.95 per month, $4,163 per year
- 40%: $774.16 per month, $9,290 per year
- 50%: $1,102.04 per month, $13,224 per year
The jump from 20% to 40% is roughly $5,100 per year, tax-free. The jump from 40% to 50% requires unfavorable ankylosis, which is a much harder clinical threshold to clear, and only 10 cases in my dataset cleared it.
The IVDS Alternative (Incapacitating Episodes)
The 61 cases coded under DC 5243 (intervertebral disc syndrome) have access to a rating pathway most veterans don't realize exists. Under the Plus Formula for Rating Intervertebral Disc Syndrome Based on Incapacitating Episodes, IVDS can be rated based on the cumulative duration of incapacitating episodes over the prior 12-month period:
- 10%: Incapacitating episodes having a total duration of at least one week but less than two weeks during the past 12 months
- 20%: Incapacitating episodes having a total duration of at least two weeks but less than four weeks during the past 12 months
- 40%: Incapacitating episodes having a total duration of at least four weeks but less than six weeks during the past 12 months
- 60%: Incapacitating episodes having a total duration of at least six weeks during the past 12 months
An "incapacitating episode" is defined in the regulation as a period of acute signs and symptoms due to IVDS that requires bed rest prescribed by a physician and treatment by a physician. The bed-rest order is the documentation threshold. Without a physician-prescribed bed-rest order, the episode doesn't count for this rating pathway.
The 60% IVDS tier is meaningful because it sits above the 50% unfavorable-ankylosis tier on the General Rating Formula and can be reached without ankylosis. For a veteran with documented disc disease, severe episodic flares, and physician-prescribed bed-rest orders during those flares, the IVDS pathway is the higher-rating route.
The regulation explicitly says IVDS gets rated under whichever formula yields the higher rating. So a veteran with IVDS and 35-degree forward flexion (which would yield 20% under the General Formula) could potentially get to 40% or 60% through the incapacitating-episodes formula if the bed-rest documentation supports it.
This is the part of the back-cluster rating system that's most under-utilized. Veterans whose stenosis presents with severe episodic flares but whose stable-baseline ROM is only moderately reduced often don't realize the IVDS formula is on the table. The 61 DC 5243 cases in my dataset reflect veterans who are using it. The broader population of stenosis veterans with episodic flare patterns probably includes many who could be coded under DC 5243 with the right diagnostic framing.
The Aggravation Quirk (8 Cases, 62.5% Grant)
Most condition cornerstones I analyze have aggravation claim rates around 20-30%. Spinal stenosis has aggravation as a connection theory in only 8 cases out of the 909 (less than 1 percent). But the grant rate on those 8 cases is 62.5%.
Read that with the caveat first: 8 cases is a tiny sample, and the 62.5% figure could easily move 10-20 percentage points either direction with five more cases in or out of the bucket. Don't over-interpret this number.
But the directional pattern is worth noting. Aggravation claims under Allen v. Brown, where a pre-existing condition is alleged to have been aggravated beyond natural progression during service, are notoriously hard to win across the dataset overall. The standard aggravation grant rate across the full BVA dataset is 25.3%. Spinal stenosis at 62.5% is the outlier, not the norm.
When aggravation does work for stenosis, the pattern in the small case set is that the pre-service stenosis (or pre-disposing degenerative process) is documented on entrance, the in-service worsening is supported by specific events (lifting injury, fall, persistent compressive loading), and the C&P examiner is willing to characterize the post-service condition as exceeding what natural progression would produce.
For a back claim where there's a pre-service note of mild degenerative changes that wouldn't have qualified for a disability rating, and the veteran's career involved physical loading that demonstrably accelerated the degeneration, the aggravation theory under § 3.306 is available. It's just not the path most veterans use, and the small sample size in my data reflects that.
Strong Nexus Saves 92%, Weak Nexus Sinks 99%
The nexus quality breakdown for spinal stenosis:
- Strong nexus: 73 cases, 91.8% grant
- Adequate nexus: 284 cases, 57.4% grant
- Weak nexus: 136 cases, 0.7% grant
- Missing nexus: 61 cases, 0.0% grant
- Not applicable: 355 cases, 12.4% grant
The strong-versus-weak cliff is consistent with the broader pattern I see across condition cornerstones. 91.8% grant at strong nexus, 0.7% grant at weak nexus. That's a 91-point gap. The cases either have the medical opinion that holds up the connection theory, or they don't.
What separates strong from weak in back-claim decisions specifically:
- Strong nexus opinions identify the in-service event or chronic exposure (specific lifting injury, persistent physical loading, documented in-service back complaints with specificity), explain the medical pathway from the in-service event to the current stenosis (mechanical loading → disc degeneration → spinal canal narrowing → nerve impingement), address competing causes (post-service occupational loading, normal aging degeneration), and conclude with an "at least as likely as not" statement that is supported by the body of the opinion
- Weak nexus opinions state a conclusion without supporting reasoning, fail to address what specifically in service contributed beyond a generic reference to military duty, don't engage with competing causes, or are written by a provider who didn't review the relevant treatment records
The 73 cases with strong nexus and a 91.8% grant rate represent the path that works. The 136 cases with weak nexus and a 0.7% grant rate represent the path that doesn't.
The 355 cases coded as "not applicable" for nexus are interesting. Many of these are cases where the Board didn't reach the nexus question because the appeal turned on something else (rating-tier increase, secondary connection from another already-service-connected condition, jurisdictional or procedural issues). The 12.4% grant rate in that bucket is lower than the dataset's overall 13.1% N/A rate, which is not a meaningful gap.
What I Can't Tell You From This Data
Honest limits matter.
I can't tell you whether your specific imaging findings will be characterized as stenosis-driven, disc-driven, or arthritis-driven by the C&P examiner. The radiology often supports multiple characterizations, and the examiner's clinical judgment about which is dominant is what drives the diagnostic code citation. That choice has downstream rating consequences I've described, but the choice itself isn't something the data predicts.
I can't tell you whether your forward-flexion measurement will fall on the 30-degree side or the 60-degree side of the threshold. The measurement varies day to day for many veterans with back conditions. The Correia framework is supposed to address that variability by requiring active, passive, weight-bearing, non-weight-bearing, and flare-up measurement, but the implementation across examiners is uneven.
I can't tell you whether your case should be rated under the General Rating Formula or the IVDS incapacitating-episodes formula. That depends on your specific symptom pattern, documentation of bed-rest orders, and the diagnostic code citation. Both pathways are available for DC 5243; only the General Formula applies to DC 5238 and DC 5242.
I can't tell you why the spinal stenosis case grant rate sits at 30.3% rather than higher. The 909 cases that reach the BVA are a selected population: cases where the regional office denied or under-rated, the veteran appealed, and the case stayed in the system long enough to receive a Board decision. The selection criteria filter for harder cases, and the 30.3% grant rate reflects that selection rather than the overall odds of a stenosis claim succeeding at the VA.
What the data can tell you is the structure of how these claims move at the Board. The diagnostic-code distribution matters more than veterans realize. The Correia framework drives a meaningful share of remands. The 40% tier is the modal grant, and forward flexion ≤ 30 degrees is the threshold that produces it. Strong nexus opinions matter, and weak ones don't survive.
Three Things That Move Spinal Stenosis Claims
If I were filing or appealing a stenosis claim today, the three pieces of the file I'd focus on are:
One: A C&P exam (or supplemental private exam) that satisfies Correia. The active, passive, weight-bearing, and non-weight-bearing range-of-motion measurements all need to be documented. The flare-up functional loss needs to be quantified. If your existing C&P report doesn't address these, the case is at risk of remand even if the bottom-line measurements support a grant. A private orthopedic evaluation that captures the Correia factors can fill the gap. The 31% remand rate is largely about exams that didn't address what the Court required them to address.
Two: A diagnostic-code framing that aligns with your symptom pattern. If your stenosis presents with disc involvement and episodic incapacitating flares, the IVDS pathway under DC 5243 with the incapacitating-episodes formula may produce a higher rating than the General Rating Formula. If your stenosis presents primarily as degenerative arthritis with progressive ROM restriction, DC 5242 is the natural fit. The diagnostic code is something the Board decides, but the medical record can be developed to support the more advantageous framing where it's clinically accurate.
Three: A nexus opinion that engages with the in-service event or exposure. Generic letters that say "stenosis is at least as likely as not related to military service" don't move the needle. Specific letters that identify the in-service event (lifting injury, fall, persistent physical loading), explain the medical pathway, address competing post-service causes, and document the chronicity of the condition do. The 91.8% strong-nexus grant rate is real. So is the 0.7% weak-nexus grant rate. The difference is the body of the opinion.
Bottom Line
Spinal stenosis sits inside the back-cluster at the BVA, with 909 cases distributed roughly evenly across grant (30.3%), denial (38.7%), and remand (31.0%). The General Rating Formula at 38 CFR § 4.71a governs most stenosis rating decisions, with tiers at 10%, 20%, 40%, 50%, and 100%, and the modal grant tier in my dataset is 40%, produced by forward flexion of 30 degrees or less or favorable ankylosis of the entire thoracolumbar spine. The diagnostic-code distribution matters: DC 5242 (degenerative arthritis) is the most-cited code in stenosis cases, DC 5243 (IVDS) opens an alternative rating pathway through incapacitating episodes that no other back code provides, and DC 5238 (stenosis specifically) is used in only 26 of 909 cases. Correia v. McDonald is the procedural framework driving a meaningful share of the 31% remand rate, because C&P exams that don't address active, passive, weight-bearing, and non-weight-bearing range of motion plus flare-up functional loss are inadequate as a matter of law. The strong-versus-weak nexus cliff is the same here as everywhere (91.8% versus 0.7%), and the 40% tier is what most successful Board grants land on. For veterans on the direct path, the nexus opinion that engages with the in-service event is the case. For veterans whose stenosis presents with disc involvement and episodic incapacitation, the IVDS pathway is worth considering. For veterans whose C&P exam didn't capture Correia factors, the file is vulnerable to remand and the missing measurements should be captured through supplemental private evaluation if possible.
Methodology and Limitations
- Data source: Outcome statistics, nexus-quality coding, denial-reason classification, diagnostic-code distribution, and connection-type tagging are drawn from Claim Raven's analysis of 101,518 condition records drawn from 49,876 Board decisions, including 909 spinal stenosis cases. Rating schedule framework is drawn from 38 CFR § 4.71a (General Rating Formula for Diseases and Injuries of the Spine, and the Plus Formula for IVDS based on Incapacitating Episodes). The Correia v. McDonald framework reflects the U.S. Court of Appeals for Veterans Claims 2016 decision and its implementation through subsequent BVA practice. 2026 VA disability compensation rates referenced for context (100% single vet = $4,044.91/month).
- Sample size: 909 BVA decisions involving spinal stenosis, with outcomes split 30.3% granted (275), 38.7% denied (352), 31.0% remanded (282). Connection-type subdivisions cover 625 direct, 109 secondary, 8 aggravation, and 5 presumptive. Diagnostic-code subdivisions include DC 5242 (86), DC 5243 (61), DC 5237 (26), DC 5238 (26), DC 5293 (14), and a long tail of less-cited codes. Rating-tier distribution among grants reflects the cases where a tier was clearly identified in the Board decision.
- Classification approach: Cases coded as "spinal_stenosis" based on the condition extraction from BVA decisions. Diagnostic-code coding reflects the codes the Board cited in its decision, which may or may not match the original rating decision. Nexus quality (strong/adequate/weak/missing/not_applicable) is assigned based on the Board's treatment of the medical opinion language.
- Limitations:
- The 909 stenosis cases reached the BVA. Claims granted at the regional office without appeal aren't in this dataset, and the overall VA grant rate for stenosis is almost certainly higher than 30.3%.
- The diagnostic-code distribution reflects what the Board cited, not always what the original rating decision used. Some recoding happens at the appellate level.
- The IVDS incapacitating-episodes pathway is only available under DC 5243. Veterans whose stenosis is coded under other DCs cannot access that formula even if their symptom pattern would otherwise support it.
- The Correia v. McDonald analysis here reflects the legal framework. Application varies across BVA decisions and individual judges, and not every inadequate exam gets flagged.
- The aggravation grant rate of 62.5% reflects only 8 cases. Small-sample variability makes this number unreliable as a predictor.
- Rating-tier distribution among grants reflects the 149 cases where a tier was clearly coded in the dataset. Not every grant has a clearly coded tier.
- These observations describe BVA patterns. They are not predictions of individual outcomes.
