Diabetes mellitus type II is one of the most prevalent service-connected disabilities in the VA system — and one of the most misunderstood in terms of how ratings work, what evidence matters, and what secondary conditions can be stacked on top of it. Hundreds of thousands of veterans receive compensation for diabetes, but a significant number are rated lower than the law requires because they don't understand the specific criteria under Diagnostic Code 7913.
What makes diabetes claims particularly important is the Agent Orange presumptive pathway. Veterans who served in Vietnam, certain areas of South Korea, Thailand, or at sea in the territorial waters of Vietnam don't need to prove their diabetes was caused by military service. Under 38 USC 1116 and 38 CFR 3.309(e), the VA presumes Agent Orange exposure caused the diabetes — no nexus letter required.
But the diabetes rating itself is only part of the picture. The conditions that flow from diabetes — peripheral neuropathy, retinopathy, nephropathy, coronary artery disease, erectile dysfunction, stroke, hypertension — are all ratable as secondary conditions that can be individually combined into the veteran's total rating. A veteran with a 40% diabetes rating who claims four secondary conditions may ultimately reach an 80–90% combined rating, dramatically increasing monthly compensation.
This guide covers everything: the specific rating criteria under DC 7913, every qualifying Agent Orange exposure pathway, the evidence that moves ratings from 20% to 40% to 60%, how secondary conditions compound the total, and the 2026 pay tables.
All VA disability ratings for diabetes mellitus type II are governed by 38 CFR Part 4, Subpart B, §4.119 — Schedule of Ratings, Endocrine System. Diabetes falls under Diagnostic Code 7913.
DC 7913 covers diabetes mellitus — including both type I and type II. The rating criteria are based on the treatment regimen required to control the condition, the frequency and severity of complications, and functional limitations caused by the disease and its treatment. Unlike some conditions rated solely on objective measurements, diabetes is rated on a composite of:
The benefit of the doubt standard under 38 USC 5107(b) applies: when evidence is in approximate balance between two rating levels, VA must assign the higher one. Veterans should always present evidence documenting the most severe aspects of their condition — worst episodes, treatment escalations, physician-imposed restrictions — not just average-day functioning.
The key distinction in DC 7913 is the treatment tier. Each escalation in treatment corresponds to a higher potential rating:
The following table maps the full rating scale under DC 7913 to the specific clinical criteria required at each level:
| Rating | Treatment Required | Additional Criteria |
|---|---|---|
| 10% | Restricted diet only (no medications) | Manageable by dietary modification alone |
| 20% | Oral hypoglycemic agent(s) | Diet plus one or more oral medications; no insulin required |
| 40% | Insulin + restricted diet + regulation of activities | All three required: insulin therapy, dietary control, and physician-directed activity restrictions |
| 60% | Insulin + restricted diet + regulation of activities | Plus: episodes of ketoacidosis or hypoglycemic reactions requiring at least 1–2 physician visits/year, or progressive weight loss, or peripheral neuropathy documented |
| 100% | Insulin therapy | Associated with frequent episodes of ketoacidosis, coma, or progressive end-organ complications (nephropathy, retinopathy, CAD) that are themselves seriously disabling |
To qualify for 60%, the veteran must show episodes of ketoacidosis or hypoglycemic reactions that required at least physician-level intervention — not just episodes the veteran managed at home with juice or glucose tablets. The VA is looking for documented emergency room visits, urgent care visits, physician office visits specifically to address a hypoglycemic episode or DKA event, or hospitalizations for these complications.
Veterans who experience frequent hypoglycemic episodes but manage them independently without medical visits may not automatically qualify for 60% on that basis alone — however, peripheral neuropathy (even mild), progressive weight loss, or the combination of frequent documented episodes can collectively support the higher rating. Work with your physician to ensure every significant episode is documented in the medical record.
If you use a continuous glucose monitor (CGM) or an insulin pump (continuous subcutaneous insulin infusion/CSII), this documentation is highly useful. CGM data showing frequent hypoglycemic excursions below 70 mg/dL, or hyperglycemic spikes above 250 mg/dL despite treatment, demonstrates poor control. Insulin pump use confirms insulin dependency. Bring printed CGM reports and pump download data to your C&P exam and include them with your claim evidence.
For many veterans, the most important aspect of a VA diabetes claim is not the rating itself — it's the service connection pathway. Veterans exposed to Agent Orange (tactical herbicides) do not need to prove a direct nexus between their diabetes and military service. Under the presumptive service connection framework, the VA presumes the connection exists.
The legal authority for Agent Orange presumptives includes:
Under this framework, if you served in a qualifying location during a qualifying time period and you have been diagnosed with type II diabetes, the VA is legally required to grant service connection without any nexus letter or medical opinion linking your diabetes to your service. The only things VA can evaluate are (1) whether you served in a qualifying location, and (2) the severity of your current condition for rating purposes.
The Agent Orange presumptive does not apply only to "boots on the ground" Vietnam veterans. Over decades of litigation, Congress and VA have expanded the qualifying exposure categories significantly. Here is who qualifies:
Veterans who served in the Republic of Vietnam (including offshore waters in the territorial sea) between January 9, 1962 and May 7, 1975 qualify automatically. "Service in Vietnam" includes veterans who set foot on land in Vietnam or who served on a vessel in the inland waterways of Vietnam — not just those assigned to permanent in-country billets. A single day of in-country service qualifies.
The Blue Water Navy Vietnam Veterans Act of 2019 (Public Law 116-23) extended presumptive eligibility to veterans who served on naval vessels that operated in the territorial seas and waters of Vietnam. VA maintains a database of ships that have been determined to qualify. If you served on a vessel in that database during the qualifying period, you are eligible for the Agent Orange presumptive — even if you never set foot on Vietnamese soil. See the full guide at Blue Water Navy veterans and Agent Orange.
Veterans who served in certain units in the Korean Demilitarized Zone (DMZ) area between April 1, 1968 and August 31, 1971 qualify for the presumptive. Agent Orange was used extensively along the DMZ during this period. VA maintains a list of qualifying units — if you served with a listed unit in the DMZ area during the qualifying dates, you qualify.
Veterans who served at certain Royal Thai Air Force Bases (RTAFBs) in Thailand between January 9, 1962 and May 7, 1975 may qualify if their service placed them in contact with herbicides (perimeter guard duty, base security, maintenance along perimeter). The qualifying bases include U-Tapao, Ubon, Nakhon Phanom, Udorn, Takhli, Korat, and Don Muang. This pathway requires more individualized proof that the veteran's duties placed them in an area where herbicides were used.
Veterans who served at Marine Corps Base Camp Lejeune in North Carolina for at least 30 days between August 1, 1953 and December 31, 1987 qualify for presumptive service connection for several conditions under the Camp Lejeune Justice Act. While Camp Lejeune contamination benefits are separate from Agent Orange, diabetes is not currently among the Camp Lejeune presumptive conditions — however, veterans at Lejeune with other Agent Orange or direct service connection pathways should explore all options. See Camp Lejeune PACT Act benefits.
The Sergeant First Class Heath Robinson Honoring our Promise to Address Comprehensive Toxics (PACT) Act of 2022 expanded presumptive conditions for post-9/11 veterans exposed to burn pits and other toxic exposures. While type II diabetes is not currently listed as a PACT Act presumptive, veterans who developed diabetes potentially related to burn pit or other toxic exposures should consult a VSO about direct service connection pathways. See VA claims for burn pit exposure.
Whether claiming Agent Orange presumptive or direct service connection, the strength of your evidence determines your rating level. Here is exactly what documentation you should compile:
Hemoglobin A1c levels document the average blood glucose control over the preceding 2–3 months. Bring all A1c records from at least the past 2–3 years. Key things to highlight:
Insulin use is the critical threshold between a 20% rating and a 40% rating. Document your insulin therapy with:
Documented hypoglycemic reactions are evidence for the 60% threshold. For each episode:
The 40% rating requires "regulation of activities." This means your physician must have placed documented restrictions on your physical activities due to diabetes management. Gather:
REE Medical offers free consultations to help veterans with diabetes and secondary conditions get the medical nexus support they need — especially for peripheral neuropathy and other complications.
Get a Free Medical Consultation →Diabetes mellitus is often called a "gateway" condition in VA claims because it generates so many secondary conditions — each of which is separately ratable and combinable into the veteran's total disability percentage. Veterans with service-connected diabetes should actively pursue every secondary condition their diabetes has caused or aggravated.
Diabetic peripheral neuropathy — tingling, numbness, burning pain, or weakness typically starting in the feet and progressing upward — is the most common complication of long-standing diabetes. Under VA rating criteria, each affected extremity is rated separately under the peripheral nerve diagnostic codes:
Ratings range from 10% (mild) to 40% (moderately severe) per extremity. A veteran with bilateral lower extremity neuropathy rated at 20% each, combined with a 40% diabetes rating, reaches a combined rating of approximately 55–60%, typically rounding to 60%. Add upper extremity neuropathy and the math improves further. See peripheral neuropathy secondary to diabetes VA claim.
Diabetic retinopathy — damage to the retinal blood vessels causing vision impairment — is ratable under the VA's Vision rating schedule (DC 6006–6009 and related codes) based on documented visual acuity loss and visual field defects. Proliferative retinopathy or macular edema can cause significant vision loss that warrants ratings of 20–100% for the visual impairment. An ophthalmologist report documenting retinal findings, visual acuity measurements, and visual field testing is essential evidence.
Diabetic kidney disease is rated under DC 7700 (kidney disease) based on kidney function measurements — specifically GFR (glomerular filtration rate), creatinine levels, and proteinuria. End-stage renal disease requiring dialysis or renal transplant qualifies for a 100% rating for the kidney condition alone, which would push the veteran's combined rating to 100% regardless of other ratings. Even moderate chronic kidney disease (CKD Stage 3 or 4) warrants significant ratings of 60–80%.
Diabetes is a major risk factor for coronary artery disease, and CAD is ratable as secondary to service-connected diabetes under the secondary service connection doctrine. CAD is rated under DC 7005 (ischemic heart disease) based on workload limitations and METs on exercise testing:
A 60% CAD rating combined with a 40% diabetes rating and bilateral neuropathy can reach a combined rating exceeding 90%. See Agent Orange presumptive conditions complete list — CAD (ischemic heart disease) is also separately a direct Agent Orange presumptive condition.
Diabetic neuropathy frequently causes erectile dysfunction through damage to the autonomic nerves controlling penile blood flow. Neurogenic ED secondary to diabetic neuropathy qualifies for a flat Special Monthly Compensation (SMC-K) rate, currently approximately $123.04/month in addition to other compensation. It is also ratable under DC 7522 at 0% with the SMC-K add-on for loss of use of a creative organ. See VA claim for erectile dysfunction secondary to service-connected condition.
Diabetes significantly increases stroke risk. If a veteran suffers a stroke and has service-connected diabetes, the stroke may be ratable as a secondary condition under DC 8007 (cerebrovascular accident) or related codes. Residual neurological deficits from stroke are rated based on the degree of functional impairment — hemiplegia, aphasia, cognitive impairment — and can reach very high ratings depending on severity.
Hypertension is frequently secondary to or aggravated by diabetes through insulin resistance, renal mechanisms, and metabolic syndrome pathways. If the veteran's hypertension developed or worsened after developing service-connected diabetes, it may be separately ratable as secondary to diabetes under DC 7101. See the hypertension secondary condition VA claim guide for documentation strategies applicable to any secondary hypertension claim.
Living with chronic insulin-dependent diabetes — managing glucose levels, dietary restrictions, fear of hypoglycemia, progressive complications — frequently causes or aggravates major depressive disorder and anxiety disorders. Depression secondary to service-connected diabetes is ratable under DC 9434 (MDD) or DC 9400 (GAD) at 0–100%. See VA disability rating for depression for the full rating criteria.
Diabetes causes macrovascular disease — atherosclerosis of the peripheral arteries — leading to reduced blood flow to the extremities. Peripheral arterial disease may require bypass surgery, angioplasty, or ultimately amputation. Amputations are rated at high fixed rates (40–60%+ per limb depending on level), and the underlying PAD is separately ratable. Document any ankle-brachial index (ABI) measurements below 0.9, which confirms arterial insufficiency.
The following monthly compensation rates apply for 2026. These are the rates for the veteran's overall combined rating — which includes diabetes plus all secondary conditions. All VA disability compensation is completely federal income tax-free.
| Combined Rating | Veteran Only | Veteran + Spouse | Veteran + Spouse + 1 Child |
|---|---|---|---|
| 10% | $175.51 | $175.51 | $175.51 |
| 20% | $346.95 | $346.95 | $346.95 |
| 30% | $537.42 | $601.58 | $650.40 |
| 40% | $774.16 | $854.61 | $917.93 |
| 50% | $1,102.04 | $1,196.48 | $1,274.27 |
| 60% | $1,395.93 | $1,506.27 | $1,598.84 |
| 70% | $1,759.43 | $1,885.65 | $1,993.41 |
| 80% | $2,044.89 | $2,186.42 | $2,309.52 |
| 90% | $2,297.96 | $2,454.80 | $2,593.25 |
| 100% | $3,938.58 | $4,206.04 | $4,393.95 |
Note: At 30%+, dependents (spouse, children, dependent parents) add to monthly compensation. The 100% rate reflects 2026 figures. Veterans rated at 100% who have certain severe conditions may qualify for Special Monthly Compensation (SMC) above the standard 100% rate — for example, veterans with housebound status, loss of use of extremities, or blindness. See 100% disabled veteran benefits 2026 complete guide.
Veterans whose diabetes (combined with secondary conditions) doesn't quite reach a combined 100% schedular rating may still qualify for Total Disability based on Individual Unemployability (TDIU), which pays at the 100% rate. TDIU requires that the veteran is unable to maintain substantially gainful employment due to service-connected conditions. A veteran with a 40% diabetes rating and bilateral neuropathy preventing sustained standing or sedentary work due to pain may qualify for TDIU even at a 60–70% combined rating. See TDIU vs. 100% schedular — which pays more.
Your Compensation and Pension (C&P) exam for diabetes is critical. Here is how to prepare:
Request a copy of the C&P exam report. If the examiner failed to address your secondary complications, understated your treatment intensity, or incorrectly characterized your activity limitations, file a rebuttal with your Supplemental Claim or HLR. A private physician opinion (IMO) from an endocrinologist that directly addresses errors in the C&P report is powerful rebuttal evidence. See diabetes C&P exam preparation guide.
If your diabetes claim was denied or rated lower than the evidence supports, you have clear appeal options:
If you're on insulin with documented activity restrictions and received only a 20% rating, that is a clear and unmistakable error (CUE) in applying DC 7913. File a Higher-Level Review (VA Form 20-0996) and identify the specific regulatory criteria (DC 7913, 40% threshold) that requires a higher rating. Request an informal conference to walk the reviewer through the evidence.
If you served in a qualifying location and were denied service connection for diabetes because VA claimed no nexus was established, file a Supplemental Claim citing 38 CFR 3.307 and 3.309(e) explicitly. The VA cannot require a nexus opinion for Agent Orange presumptive conditions — any denial on those grounds is legally defective.
If you have secondary conditions (neuropathy, retinopathy, nephropathy, CAD, ED) that were never claimed, file them now as secondary to your service-connected diabetes. There is no time limit for claiming secondary conditions. The effective date will generally be the date of your new claim, so filing sooner means more back pay. See VA Supplemental Claim guide.
Secondary conditions like peripheral neuropathy and CAD require a nexus opinion linking them to your service-connected diabetes. A nexus letter from your treating physician or a private specialist should state: "It is at least as likely as not that [condition] was caused by or is the result of the veteran's service-connected diabetes mellitus type II." See nexus letter for diabetes secondary conditions.
Yes. Ischemic heart disease (coronary artery disease) is separately listed as an Agent Orange presumptive condition under 38 CFR 3.309(e). If you served in a qualifying location and developed both type II diabetes and CAD, you can claim both as separate Agent Orange presumptives. Each is rated separately and combined into your overall rating. You do not need to choose between them — they are independent presumptive conditions.
VA rates based on the treatment required to achieve that control, not just the control level itself. A veteran whose diabetes is "controlled" on insulin with activity restrictions still qualifies for 40%, because it takes insulin AND activity restrictions to maintain that control. Don't let a "well-controlled" label on your chart lead you to assume your rating is lower — what matters is what treatment is required, not whether it's working.
For Agent Orange presumptive conditions, the timing of diagnosis doesn't matter — only that you served in a qualifying location and currently have the condition. Type II diabetes frequently develops years or decades after exposure. As long as you served in Vietnam, Korea DMZ, qualifying Thai bases, or qualifying Blue Water Navy vessels and currently have a type II diabetes diagnosis, you qualify for the presumptive regardless of when the diagnosis was made.
CHAMPVA (Civilian Health and Medical Program of the VA) is available to dependents of veterans who are permanently and totally (P&T) disabled. If your diabetes and secondary conditions result in a 100% rating that is also classified as permanent (unlikely to improve), your spouse and children may be eligible for CHAMPVA healthcare coverage — a significant benefit. See CHAMPVA eligibility guide.
Standard claim processing times vary but typically run 3–6 months for new claims and 4–8 months for appeals at the regional office level. Agent Orange presumptive claims should process somewhat faster since no nexus development is required. Filing via fully developed claim (FDC) with all evidence upfront can reduce processing time. See the full VA claims process guide.
