How does the VA rate Type 2 diabetes?

Under 38 CFR 4.119 Diagnostic Code 7913. Six brackets: 10% managed by restricted diet only; 20% requires insulin and restricted diet OR oral hypoglycemic agent and restricted diet; 40% requires insulin, restricted diet, AND regulation of activities; 60% adds episodes of ketoacidosis or hypoglycemic reactions requiring 1-2 hospitalizations per year or twice-monthly visits to a diabetic care provider, plus complications that would not be compensable if separately evaluated; 100% requires more than one daily injection of insulin, restricted diet, 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, plus either progressive loss of weight and strength or complications that would be compensable if separately evaluated.

Is Type 2 diabetes Agent Orange presumptive?

Yes, under 38 CFR 3.309(e). Vietnam-era veterans who served in the Republic of Vietnam between January 9, 1962 and May 7, 1975 (boots-on-ground, inland waterways, or now under Procopio v. Wilkie and the Blue Water Navy Vietnam Veterans Act of 2019, 12-nautical-mile territorial sea) receive a presumption that Type 2 diabetes is service-connected. The PACT Act of 2022 expanded qualifying locations to include Thailand, Laos, Cambodia, Guam, American Samoa, and Johnston Atoll for specified service periods.

What is regulation of activities?

A specific term in DC 7913 meaning the veteran has been medically directed to avoid strenuous occupational AND recreational activities to prevent hypoglycemia or worsen diabetic control. The Federal Circuit in Camacho v. Nicholson, 21 Vet. App. 360 (2007), held that regulation of activities must be specifically prescribed by a physician — generic dietary advice or general exercise recommendations do not qualify. The medical record must contain an explicit instruction limiting activity. This bracket-jump (from 20% to 40%) is often the single largest rating gain for a diabetic veteran whose providers have not documented activity regulation.

Are diabetes complications rated separately?

Yes. Peripheral neuropathy (sensorimotor or autonomic), diabetic retinopathy, diabetic nephropathy, cardiovascular complications (coronary artery disease, hypertension), erectile dysfunction, and skin conditions are each rated under their own diagnostic codes and combined with the underlying diabetes rating under 38 CFR 4.25. Note 1 to DC 7913 specifically allows separate ratings for complications unless the complication is part of the criteria used to support a higher diabetes rating (anti-pyramiding under 38 CFR 4.14).

How is peripheral neuropathy rated?

Under 38 CFR 4.124a Diagnostic Code 8520 (sciatic nerve) for lower extremity, or DC 8515 (median nerve) for upper extremity, etc. Each nerve is rated separately per extremity. Mild incomplete paralysis = 10%, moderate = 20%, moderately severe = 40%, severe = 60%, complete = 80% (lower extremity). A veteran with bilateral lower-extremity diabetic neuropathy at the moderate level captures 20% + 20% combined under 38 CFR 4.25 (with bilateral factor under 38 CFR 4.26 adding 10% to the bilateral combined value before combining with other ratings).

Should I file separately for each complication?

Yes. The complications-stacking strategy is the single highest-yield approach to a diabetes claim. A 20% diabetes rating combined with bilateral lower-extremity neuropathy (20% each), nephropathy (30% for renal dysfunction), and erectile dysfunction (0% schedular but Special Monthly Compensation K) often produces a combined rating of 60-80%, far above the diabetes-only baseline. File the diabetes claim with all known complications listed in the same submission, supported by current medical records and physician statements.

What evidence does the AO presumption require?

DD-214 or other service documentation showing qualifying service location and period; for Blue Water Navy claims, ship deck logs or NPRC records showing operation within 12 nautical miles of the Vietnam coast; current diagnosis of Type 2 diabetes (HbA1c, fasting glucose, or oral glucose tolerance test results). The veteran does not need to prove an Agent Orange nexus once qualifying service and current diagnosis are established — the presumption supplies the connection.

What about Special Monthly Compensation?

Veterans with erectile dysfunction secondary to diabetes typically qualify for SMC-K (loss of use of a creative organ) under 38 USC 1114(k). SMC-K is paid in addition to the schedular rating and does not affect the combined percentage. The 2026 SMC-K rate is approximately $139.87/month and stacks on top of all other compensation. Veterans with severe diabetic complications producing loss of use of an extremity or requiring aid and attendance may qualify for higher SMC levels.

Type 2 Diabetes VA Rating

By Shirley Chia. Published 2026-05-31. Source: 38 CFR 4.119 (DC 7913), 38 CFR 3.309(e) (AO presumptive).

TL;DR. Type 2 diabetes is rated under 38 CFR 4.119 DC 7913 in six brackets: 10% (diet only), 20% (insulin or oral plus diet), 40% (insulin plus diet plus regulation of activities), 60% (the 40% picture plus ketoacidosis/hypoglycemic episodes requiring 1-2 hospitalizations/year), 100% (more than one daily insulin injection plus diet plus regulation of activities plus three or more hospitalizations/year). The bracket-jump from 20% to 40% turns on whether a physician has explicitly directed regulation of activities under Camacho v. Nicholson. Diabetes complications — peripheral neuropathy, retinopathy, nephropathy, cardiovascular disease, erectile dysfunction — are rated separately and combine under 38 CFR 4.25. Vietnam-era veterans with qualifying service receive an Agent Orange presumption under 38 CFR 3.309(e). The PACT Act of 2022 expanded qualifying locations.

The six brackets under DC 7913

Rating	Criteria	2026 monthly comp (w/ spouse)
10%	Managed by restricted diet only	$180.42
20%	Requiring insulin and restricted diet, OR oral hypoglycemic agent and restricted diet	(between 10% and 30% combined)
40%	Requiring insulin, restricted diet, and regulation of activities	(combined per 4.25)
60%	40% picture PLUS episodes of ketoacidosis or hypoglycemic reactions requiring 1-2 hospitalizations per year or twice-monthly visits to a diabetic care provider, PLUS complications that would not be compensable if separately evaluated	(combined per 4.25)
100%	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, PLUS either progressive loss of weight and strength OR complications that would be compensable if separately evaluated	$4,158.17

Two intermediate values (20% and 60%) do not appear in the 2026 spouse table above because the standard reference rates run at the 10/30/50/70/100 grid; intermediate values are computed via 38 CFR 4.25 combined ratings.

The Camacho rule on regulation of activities

Camacho v. Nicholson, 21 Vet. App. 360 (2007), held that the 40% bracket's "regulation of activities" requirement means the medical record must contain a specific physician directive limiting strenuous occupational AND recreational activity to prevent hypoglycemia or to manage diabetic control. Generic recommendations to exercise or general dietary advice are not enough. The directive must be explicit.

This holding produces one of the most consistent under-ratings in VA practice. Many diabetic veterans on insulin function at the 40% level clinically — they are limited in occupation and recreation by hypoglycemia risk — but their medical records lack the explicit directive. The fix is straightforward: request that the treating endocrinologist document the activity limitation in the chart and provide a brief statement for the claim file.

The Agent Orange presumptive pathway

Under 38 CFR 3.309(e), the following Vietnam-era veterans are presumptively service-connected for Type 2 diabetes:

Republic of Vietnam service. Boots-on-ground service in Vietnam between January 9, 1962 and May 7, 1975.
Inland waterways. Service on vessels operating on the inland waterways of Vietnam (brown water).
Blue Water Navy. Service on a vessel operating within 12 nautical miles of the Vietnam coast (territorial sea), per Procopio v. Wilkie, 913 F.3d 1371 (Fed. Cir. 2019) (en banc) and the Blue Water Navy Vietnam Veterans Act of 2019, Pub. L. 116-23.
Thailand. Service at certain Thai air bases (Korat, Takhli, Nakhon Phanom, Ubon, Udorn, U-Tapao, Don Muang) between January 9, 1962 and June 30, 1976 (PACT Act 2022 expansion).
Laos, Cambodia, Guam, American Samoa, Johnston Atoll. Specified service locations and dates added by the PACT Act under 38 CFR 3.307(a)(6) and related provisions.

The presumption attaches when (1) qualifying service is established and (2) Type 2 diabetes is currently diagnosed. The veteran is not required to prove an Agent Orange nexus or in-service exposure event. The list of presumptive diseases in 3.309(e) is updated periodically — Type 2 diabetes was added in 2001.

Manifestation timing

Under 38 CFR 3.307(a)(6)(ii), Type 2 diabetes must manifest to a degree of 10% or more at any time after service. There is no time limit — late-onset diabetes diagnosed 30 or 40 years after Vietnam service still qualifies. This is the practical reason many Vietnam-era veterans file diabetes claims in their 60s, 70s, and 80s.

The complication-stacking strategy

The single highest-yield insight for diabetes claims is that complications are rated separately. Note 1 to DC 7913 specifically allows separate ratings for compensable complications, subject to anti-pyramiding under 38 CFR 4.14 (a complication used to support a higher diabetes bracket cannot also be separately rated).

Peripheral neuropathy

Diabetic peripheral neuropathy is rated under 38 CFR 4.124a, most commonly DC 8520 (sciatic nerve) for lower extremity. Each extremity rated separately. Brackets: 10% mild incomplete paralysis, 20% moderate, 40% moderately severe, 60% severe with marked muscular atrophy, 80% complete paralysis.

Bilateral involvement triggers the 38 CFR 4.26 bilateral factor: after combining the two extremity ratings, add 10% of the combined value, then combine that result with other ratings.

Diabetic retinopathy

Rated under 38 CFR 4.79 (eye disorders), with the impact on visual acuity and visual field driving the percentage. Mild nonproliferative retinopathy without visual loss may rate 0%; proliferative retinopathy with macular edema and significant visual loss may rate 30%, 50%, 70%, or higher per the visual acuity tables under DC 6066.

Diabetic nephropathy

Rated under 38 CFR 4.115a (renal involvement) at 0%, 30%, 60%, 80%, or 100% based on creatinine clearance, BUN, and constitutional symptoms. Even early albuminuria with elevated BUN can support a 30% rating.

Cardiovascular complications

Coronary artery disease secondary to diabetes is rated under 38 CFR 4.104 (DC 7005) based on workload METs and ejection fraction. Hypertension secondary to diabetes is rated under DC 7101 (see the hypertension rating guide).

Erectile dysfunction

Diabetic ED is rated under 38 CFR 4.115b DC 7522 (penis deformity with loss of erectile power) at 20% if a physical deformity is present; otherwise 0% schedular. The 0% rating still triggers Special Monthly Compensation K (SMC-K) under 38 USC 1114(k) for loss of use of a creative organ, paid at approximately $139.87/month in 2026 in addition to all other compensation.

Worked example

Army veteran, 11B infantryman, served in Vietnam April 1968 to May 1969. Currently 76 years old. Files diabetes claim in 2026.

Service eligibility. DD-214 confirms qualifying Vietnam service. Agent Orange presumption under 38 CFR 3.309(e) applies without further proof.

Current diagnosis. Type 2 diabetes diagnosed 2009. Currently on metformin 1000 mg twice daily plus insulin glargine 30 units at bedtime plus insulin lispro at meals. HbA1c 7.8%. Endocrinology notes 2024 document directive to avoid strenuous activity to prevent hypoglycemia.

Diabetes rating analysis. Insulin (more than one daily injection — basal plus mealtime), restricted diet, AND regulation of activities documented in endocrinology note. No documented hospitalizations for ketoacidosis or hypoglycemia. This fits the 40% bracket. (Not 60% because no hospitalizations or twice-monthly visits; not 100% because no progressive loss of weight and strength.)

Diabetes rating: 40%.

Complications.

Bilateral lower-extremity peripheral neuropathy, moderate (positive monofilament test absent, decreased vibration sense, paresthesias documented). DC 8520 right leg = 20%; left leg = 20%. Combined under 4.25 with bilateral factor under 4.26.
Mild nonproliferative diabetic retinopathy without visual loss. DC 6066 = 0%.
Early diabetic nephropathy. Microalbuminuria with creatinine clearance 65 mL/min, BUN 28. DC 7530 / 4.115a = 30%.
Erectile dysfunction. DC 7522 = 0% schedular; SMC-K = $139.87/month.

Combined rating computation under 38 CFR 4.25.

Diabetes 40% combined with right LE neuropathy 20%: 1 - (0.60 × 0.80) = 1 - 0.48 = 0.52 → 52%.
52% combined with left LE neuropathy 20%: 1 - (0.48 × 0.80) = 1 - 0.384 = 0.616 → 62%, rounded to 60%.
Bilateral factor under 4.26: combined value of the two LE neuropathies is approximately 36% (20% + 20% combined). 10% of 36% = 3.6, added to 36 = 39.6%. Replace the 36% LE-combined with 39.6% in the chain. After re-running, the combined rating shifts modestly upward.
Add nephropathy 30%: 1 - (0.40 × 0.70) approximation → combined approximately 71%, rounded to 70%.
SMC-K added on top: $139.87/month.

Final combined schedular rating: 70%.

2026 monthly compensation. 70% with spouse = $1,961.45; plus SMC-K $139.87 = $2,101.32/month. Annual = $25,216.

Compared to diabetes-only. 40% diabetes alone with spouse falls between $617.47 (30%) and $1,241.90 (50%) brackets, approximately $883/month. The complication-stacking strategy nearly tripled monthly compensation.

TDIU consideration. 70% combined with one condition at 40%+ meets the schedular threshold under 38 CFR 4.16(a). If the diabetic complications prevent substantially gainful employment, TDIU pays at the 100% rate ($4,158.17/month with spouse). See the TDIU guide.
