Diabetes is one of the most common service-connected conditions for Vietnam-era veterans, because type 2 diabetes is on the Agent Orange presumptive conditions list at 38 CFR § 3.309(e). A veteran with covered service who develops type 2 diabetes is presumed service connected without a nexus opinion. After that, Diagnostic Code 7913 sets the rating, and its tiers turn on a short list of facts: insulin or an oral agent, a restricted diet, regulation of activities, and how often the diabetes puts you in the hospital or in front of your diabetic care provider.
Across 17,378 decided Board rulings on diabetes from 2021 to 2026, 24.5% were granted, 32.8% denied and 42.7% remanded. A ruling is one issue the Board decided in one decision; one decision often rules on several issues. That grant rate is close to the 24.7 percent across all decided Board rulings, and it reads low for a reason. Clean presumptive grants usually happen at the regional office and never reach the Board. What reaches the Board is the harder subset: the 20 versus 40 percent fight over regulation of activities, complications, and direct claims where the presumption does not apply.
This page covers the DC 7913 rating chart, the regulation of activities rule, how complications are rated, the Agent Orange presumption and the other ways to prove service connection, the C&P exam, why claims get denied, and the secondary claims diabetes supports.
TL;DR
- Diabetes is rated under 38 CFR § 4.119, Diagnostic Code 7913, at 10, 20, 40, 60 and 100 percent. Every tier above 10 percent is a list of requirements, and all of them have to be in the record.
- 20 percent requires insulin or an oral hypoglycemic agent, plus a restricted diet. 40 percent requires insulin, a restricted diet and regulation of activities, meaning avoidance of strenuous occupational and recreational activities.
- Under Camacho v. Nicholson (2007), regulation of activities has to be shown by medical evidence that the restriction is medically necessary. Your own account is not enough.
- Compensable complications such as neuropathy or kidney disease are rated separately. Noncompensable ones are part of the diabetes rating (Note 1 to DC 7913).
- Type 2 diabetes is presumed service connected for veterans with covered herbicide service (38 CFR § 3.309(e) and 38 U.S.C. § 1116). The presumption does not name type 1 diabetes.
- Diabetes that reached 10 percent within one year of separation can also be presumed service connected as a chronic disease (38 CFR §§ 3.307(a)(3) and 3.309(a)), whatever the type.
Diabetes VA rating chart (DC 7913)
38 CFR § 4.119, Diagnostic Code 7913 (Diabetes mellitus), reads as follows.
Requiring more than one daily injection of insulin, restricted diet, and regulation of activities (avoidance of strenuous occupational and recreational activities) with episodes of ketoacidosis or hypoglycemic reactions requiring at least three hospitalizations per year or weekly visits to a diabetic care provider, plus either progressive loss of weight and strength or complications that would be compensable if separately evaluated: 100%
Requiring one or more daily injection of insulin, restricted diet, and regulation of activities with episodes of ketoacidosis or hypoglycemic reactions requiring one or two hospitalizations per year or twice a month visits to a diabetic care provider, plus complications that would not be compensable if separately evaluated: 60%
Requiring one or more daily injection of insulin, restricted diet, and regulation of activities: 40%
Requiring one or more daily injection of insulin and restricted diet, or; oral hypoglycemic agent and restricted diet: 20%
Manageable by restricted diet only: 10%
Note (1): Evaluate compensable complications of diabetes separately unless they are part of the criteria used to support a 100-percent evaluation. Noncompensable complications are considered part of the diabetic process under DC 7913.
Note (2): When diabetes mellitus has been conclusively diagnosed, do not request a glucose tolerance test solely for rating purposes.
Every tier above 10 percent is conjunctive. Each element has to be in the record, and one missing element drops the rating a tier.
- 20 percent has two routes: insulin plus a restricted diet, or an oral hypoglycemic agent plus a restricted diet.
- 40 percent requires insulin. A veteran on oral medicine alone stays at 20 percent even with documented activity limits, because the 40 percent row names insulin, a restricted diet and regulation of activities together.
- 60 percent adds episodes of ketoacidosis or hypoglycemic reactions that required one or two hospitalizations a year or visits to a diabetic care provider twice a month, plus complications that would not be compensable on their own.
- 100 percent requires more than one daily insulin injection, at least three hospitalizations a year or weekly visits for those episodes, and either progressive loss of weight and strength or complications that would be compensable on their own.
At the rates effective December 1, 2025 (the 2026 rates), a veteran with no dependents is paid $356.66 a month at 20 percent and $795.84 at 40 percent. That $439.18 monthly difference is why the regulation of activities question gets fought so hard.
Regulation of activities: the line between 20 and 40 percent
The 40 percent tier needs three things: insulin, a restricted diet and regulation of activities. The first two are usually plain in the treatment records. The third is where most diabetes rating disputes live.
DC 7913 defines the phrase inside its 100 percent row: "avoidance of strenuous occupational and recreational activities." In Camacho v. Nicholson, 21 Vet. App. 360 (2007), the Court of Appeals for Veterans Claims applied that definition to the 40 percent tier and held that "medical evidence is required to support this criterion." In that case the appellant's employer had stopped the appellant from driving other people at work, and the Court found that was not enough, because the record did not show it was medically necessary to regulate activities because of the diabetes.
The practical effect is that you cannot win 40 percent by describing how you have cut back on your own. A treating clinician has to say that avoiding strenuous work and recreational activity is part of managing your diabetes. The VA Diabetes Mellitus DBQ asks the examiner this question directly and adds that, for VA purposes, regulation of activities means avoiding strenuous activity "with the intention of avoiding hypoglycemic episodes." The DBQ also asks for examples.
Records that tend to carry this element include the following.
- An endocrinology or primary care note that tells you to avoid strenuous exercise or heavy physical work to prevent low blood sugar
- A treatment plan that lists activity restriction as part of diabetes management
- A clinician's statement, written for the claim, that names the activities you must avoid and why
The statement does not need to be long. It needs to come from a clinician, cover both work and recreation, and tie the restriction to the diabetes. The Board section below shows how rating appeals on diabetes have gone compared with service connection appeals.
How diabetes complications are rated
Note (1) to DC 7913 decides how complications enter the rating, and it works in two directions.
- A compensable complication gets its own rating. If diabetic neuropathy, kidney disease or an eye condition is severe enough to rate 10 percent or more under its own code, VA rates it separately and combines it with the diabetes. The one exception is when that complication is being used to support a 100 percent diabetes rating.
- A noncompensable complication stays inside the diabetes rating. It is part of the diabetic process under DC 7913, and it is one of the elements of the 60 percent tier.
The DBQ asks the examiner about the complications VA recognizes (diabetic peripheral neuropathy, diabetic nephropathy or renal dysfunction, and diabetic retinopathy) and then about conditions that are at least as likely as not the result of the diabetes: erectile dysfunction, female sexual arousal disorder, heart conditions, hypertension in the presence of diabetic kidney disease, peripheral vascular disease, stroke, skin conditions and other eye conditions. Each one checked should lead to its own exam.
Two rating rules are worth knowing. Kidney involvement is rated under DC 7541, which says to rate it as renal dysfunction. Erectile dysfunction is rated 0 percent under DC 7522, with a direction to review special monthly compensation under 38 CFR § 3.350, which pays SMC(k) for loss of use of a creative organ on top of the regular monthly rate.
How to prove service connection for diabetes
There are three main routes, and for many veterans the first one settles the question.
The Agent Orange presumption for type 2 diabetes
38 CFR § 3.309(e) lists "Type 2 diabetes (also known as Type II diabetes mellitus or adult-onset diabetes)" among the diseases presumed service connected for a veteran exposed to an herbicide agent. The statute says the same thing at 38 U.S.C. § 1116(a)(2)(H). Under 38 CFR § 3.307(a)(6)(ii), type 2 diabetes can appear at any time after service, as long as it reaches 10 percent, and diet-controlled diabetes already rates 10 percent.
Exposure is presumed for covered service. Under 38 U.S.C. §§ 1116, 1116A and 1116B and VA's Agent Orange eligibility page, that includes service in these places and periods.
- The Republic of Vietnam, its inland waterways, or offshore within 12 nautical miles, from January 9, 1962, through May 7, 1975
- Any U.S. or Royal Thai base in Thailand, from January 9, 1962, through June 30, 1976
- Laos, from December 1, 1965, through September 30, 1969
- Mimot or Krek, Kampong Cham Province, Cambodia, from April 16 through April 30, 1969
- Guam or American Samoa or their territorial waters, from January 9, 1962, through July 31, 1980, or Johnston Atoll or a ship that called there, from January 1, 1972, through September 30, 1977
- In or near the Korean DMZ, from September 1, 1967, through August 31, 1971
- Certain Air Force duty on C-123 aircraft used to spray herbicides (38 CFR § 3.307(a)(6)(v))
Presumed exposure gives way only to affirmative evidence that you were not exposed, and the presumption as a whole can be rebutted only by affirmative evidence under 38 CFR § 3.307(d). Two things decide most of these claims: records that put you in a covered place and period, and a diagnosis the record names as type 2. The presumptive conditions tool checks a service history against the lists.
Diabetes that began in service or within a year of separation
Diabetes mellitus is on the chronic disease list at 38 CFR § 3.309(a). If it reached 10 percent within one year of separation, it can be presumed service connected under § 3.307(a)(3). This route does not depend on the type, so it is the usual presumptive path for type 1 diabetes.
Outside both presumptions, the claim is direct. Under 38 CFR § 3.303(d), a disease first diagnosed after service can still be service connected when all the evidence shows it began in service. That usually takes in-service blood sugar results or symptoms in the service treatment records, plus a medical opinion that explains the link.
The diabetes C&P exam and DBQ
The Diabetes Mellitus DBQ follows DC 7913 almost line for line, so the exam is where the rating gets built. The current form asks the examiner to record these items.
- Treatment: restricted diet, oral hypoglycemic agent, insulin, and whether insulin is one injection a day or more than one
- Whether you require regulation of activities as part of managing the diabetes, with examples
- How often you see your diabetic care provider for ketoacidosis or hypoglycemia: less than twice a month, twice a month, or weekly
- How many episodes of each required hospitalization over the past 12 months
- Progressive unintentional weight loss and loss of strength, measured against your baseline weight, which the form defines as your average weight for the two years before the diabetes began
- Complications, each with its own questionnaire
Bring what proves each line. That means the medication list with insulin doses, the diet instructions, any clinician note on activity restriction, hospital discharge summaries for low blood sugar or ketoacidosis, and a count of diabetes visits over the last year. If the examiner marks "no" on regulation of activities and your treating clinician has written otherwise, that conflict is worth raising right away. C&P exam prep walks through the form before the appointment.
Why VA denies diabetes claims
Most diabetes denials and low ratings trace back to a few gaps, and each one has a fix.
Covered service is not shown. The file says "Vietnam era" but nothing places you in a covered location. The fix is the personnel record, unit history, ship deck logs or base records that put you there during the dates above.
The type of diabetes is not stated. The herbicide presumption names type 2 diabetes. If the records say only "diabetes mellitus," ask your clinician to state the type in the chart.
No medical evidence of regulation of activities. This is the most common reason a rating stays at 20 percent. The fix is a clinician's statement that avoiding strenuous occupational and recreational activities is medically necessary for your diabetes (Camacho).
The restricted diet is not documented. The 20 percent tier needs the diet along with the medicine. A note that the treatment plan includes a restricted diet closes that gap.
Complications were never claimed or examined. VA rates only what is in front of it. Neuropathy, kidney disease, eye disease and erectile dysfunction each need a diagnosis, an exam and, when they are not presumed, a link to the diabetes.
A direct or secondary opinion with no reasoning. The Court of Appeals for Veterans Claims has said that "most of the probative value of a medical opinion comes from its reasoning" (Nieves-Rodriguez v. Peake, 22 Vet. App. 295 (2008)). An opinion that states a conclusion without explaining it carries little weight on either side.
The Board section below shows how the Board ruled on diabetes appeals and why it denied or remanded them.
Secondary claims built on diabetes
Diabetes is the cause behind a long list of secondary claims. Under 38 CFR § 3.310, a condition that diabetes caused or made worse is service connected too and rated on its own. In the Board's 2021 to 2026 rulings, the conditions most often claimed secondary to diabetes were nerve conditions of the legs and arms, erectile dysfunction, hypertension, kidney disease, sleep apnea and retina conditions. Secondary conditions to diabetes covers each one, which to file first and the Board's numbers for every pair. Peripheral neuropathy, kidney disease, diabetic retinopathy and erectile dysfunction each have their own rating page.
The rating math is why this matters. A diabetes rating of 20 percent is modest on its own, but every compensable complication adds its own rating, and under 38 CFR § 4.16(a) disabilities from a common cause count as one disability toward the 60 percent single-disability threshold for TDIU.
The chain can also run the other way, with diabetes claimed secondary to another service-connected condition. In the Board's rulings, PTSD and hypertension were the conditions diabetes was most often claimed secondary to. Diabetes secondary to hypertension covers what the research supports, the blood pressure medicine route, and when the Agent Orange presumption is the better claim.
Questions veterans ask about diabetes
What is the VA rating for type 2 diabetes?
It depends on treatment, not on the type. Diet alone rates 10 percent, insulin or an oral agent with a restricted diet rates 20 percent, and insulin with a restricted diet and medically required regulation of activities rates 40 percent. The 60 and 100 percent tiers add hospitalizations or frequent visits for low blood sugar or ketoacidosis.
Is type 2 diabetes presumptive for Agent Orange?
Yes. Type 2 diabetes is listed in 38 CFR § 3.309(e) and 38 U.S.C. § 1116, so a veteran with covered service does not need a nexus opinion. You still need the diagnosis and records that place you in a covered location and period.
What does regulation of activities mean for a VA diabetes rating?
It means avoiding strenuous occupational and recreational activities because of your diabetes. Under Camacho v. Nicholson, a clinician has to show that the restriction is medically necessary; your own account of slowing down is not enough.
Are diabetes complications rated separately?
Yes, when they are compensable on their own. Note 1 to DC 7913 rates compensable complications separately and treats noncompensable ones as part of the diabetes rating, except when a complication is used to support a 100 percent diabetes rating.
Can diabetes and its complications count as one disability for TDIU?
They can. Under 38 CFR § 4.16(a), disabilities resulting from a common cause count as one disability for the 60 percent single-disability threshold, so diabetes and the complications it caused can be added together for that test. The TDIU guide covers the rest of the proof.
Bottom Line
Diabetes is rated under 38 CFR § 4.119, DC 7913, from 10 percent for diet control to 100 percent for insulin several times a day with frequent hospitalizations and progressive decline or compensable complications. The 20 to 40 percent step is the one most veterans fight over, and under Camacho v. Nicholson it needs insulin plus medical evidence that avoiding strenuous work and recreation is necessary, not just your own report. Type 2 diabetes is presumed service connected for covered herbicide service, and any type can be presumed when it reached 10 percent within a year of separation. Complications are rated separately when they are compensable on their own, which is why the claims built on diabetes often matter more to the combined rating than the diabetes itself.
Methodology and Limitations
- Data source: Rating criteria and notes are quoted from 38 CFR § 4.119, DC 7913, as published on eCFR (current through October 2026). Complication rules come from Note 1 to DC 7913, DC 7541 and DC 7522 in 38 CFR § 4.115b, and 38 CFR § 3.350(a). Presumptions come from 38 CFR §§ 3.307 and 3.309(a) and (e), 38 U.S.C. §§ 1116, 1116A and 1116B, and VA's Agent Orange eligibility page (last updated September 16, 2025). Direct and secondary service connection follow 38 CFR §§ 3.303 and 3.310, and TDIU follows 38 CFR § 4.16. Case law: Camacho v. Nicholson, 21 Vet. App. 360 (2007), and Nieves-Rodriguez v. Peake, 22 Vet. App. 295 (2008). Exam content follows VA's Diabetes Mellitus DBQ (version updated March 16, 2026). Compensation figures are VA disability rates effective December 1, 2025 (the 2026 rates) for a veteran with no dependents.
- Sample size: 511,036 Board decisions from 2021 to 2026 containing 1,378,030 rulings, including 17,378 decided Board rulings on diabetes (18,959 rulings in all, counting dismissed and withdrawn issues), with a grant rate of 24.5 percent. The BVA grant rate underrepresents the true population grant rate because clean presumptive grants typically happen at the regional office level and do not reach the Board. Denial-reason splits and rating-tier distributions are not part of this data, so I describe them in directional terms rather than precise counts.
- Limitations: The dataset captures Board-level decisions. Diabetes claims granted at the regional office without appeal are not in the sample. The herbicide exposure locations have expanded several times, most recently under the PACT Act in 2022, and older Board decisions may reflect earlier versions of the rules. The eCFR text of 38 CFR § 3.307(a)(6)(iv) still gives April 1, 1968 as the start of the Korean DMZ period; the statute and VA's eligibility page use September 1, 1967. These observations describe Board patterns and are not predictions of individual outcomes. Claim Raven is data analysis, not legal, medical, or VA-accredited advice.
