Diabetes VA claims: secondary conditions, Agent Orange and what the Board grants

How the Board of Veterans' Appeals decides diabetes claims: the Agent Orange presumption and the Thai air bases where it won most, diabetes claimed secondary to PTSD, and the nerve, kidney, eye and artery conditions that can be service connected once diabetes is.

Where VA presumes the link

Is type II diabetes presumptive for Agent Orange?

Yes. Type II diabetes is on the herbicide list in 38 CFR 3.309(e), so for a veteran with presumed herbicide exposure VA presumes the link to service without a medical opinion. In decisions that mention Agent Orange or other herbicides, the Board granted 42.4% of diabetes claims (3,114 of 7,337), against 20.0% overall.

Does service at a Thai air base count?

Yes. Since the PACT Act took effect in August 2022, VA presumes herbicide exposure for service at any United States or Royal Thai base in Thailand from January 1962 to June 1976, whatever the veteran's job or where on the base they worked (M21-1 VIII.i.1.A). Before that, exposure in Thailand had to be shown on the facts. Decisions that name a Thai air base did best: Udorn 73.0%, U-Tapao 71.4% and Korat 72.1%.

Decisions that name a base in Vietnam came out lower than the Thai bases: Da Nang 50.1% (182 of 363) and Tan Son Nhut 50.0%. The Vietnam claim map linked above follows Vietnam veterans from diabetes to the conditions that came after it.

How VA rates diabetes

How does VA rate diabetes?

Under DC 7913 in 38 CFR 4.119, from 10 percent when it is managed by diet alone to 100 percent. Complications that would be compensable on their own are rated separately unless they are part of the criteria for the highest rating; the others are part of the diabetes rating.

That rule is why the secondary conditions below matter: each one that is compensable on its own adds its own rating.

What follows from diabetes

What conditions can be claimed secondary to diabetes?

Most often nerve damage in the legs (876 of 2,384 granted, 36.7%) and arms (29.5%), hypertension (17.8%) and erectile dysfunction (28.6%). Kidney disease (46.2%), retina disease (43.2%) and peripheral artery disease (43.0%) were granted most often.

Kidney, retina and artery claims did best. Sleep apnea and glaucoma did poorly. Hypertension is often claimed this way, but for a herbicide-exposed veteran it has been presumed on its own since the PACT Act.

Diabetes claimed secondary to another condition

Can diabetes be secondary to PTSD?

Yes, under 38 CFR 3.310, with a medical opinion that explains the chain, often PTSD leading to weight gain or inactivity and that to diabetes. PTSD is the condition diabetes is most often claimed secondary to: the Board granted 93 of 403 of those claims (23.1%).

Look up your client's group

Every base, exposure, job and medal with at least 15 decided diabetes claims, 188 groups in all; 17 fall under a presumption.

Bar: share of this group's diabetes claims the Board granted. Red line: all diabetes claims, 20.0% granted. A bar past the line won more often than usual.
×
More often than usual: how much more often diabetes comes up in this group's decisions than in all Board decisions. It shows how common the condition is here, not how often it wins.
Set aside
For groups VA does not presume, veterans whose decision shows service VA already presumes for diabetes (for example Vietnam or Thailand for Agent Orange) are left out, because for them the presumption is the answer.

Read the decisions

Recent decisions, with the Board's reasoning as summarized by AI:

  • , November 2025: type II diabetes granted on presumed herbicide exposure at Takhli air base in Thailand.
  • , November 2025: type II diabetes granted on the presumption for service in Thailand, confirmed by military personnel records.
  • , December 2025: type II diabetes granted secondary to PTSD; the Board found persuasive a private opinion that PTSD led to an inactive lifestyle and metabolic changes that caused the diabetes.
  • , October 2025: a kidney condition, diagnosed as diabetic nephropathy, granted secondary to service-connected diabetes.
  • , December 2025: diabetes denied; a VA examiner found it less likely than not caused by service, noting it began after separation.

What the data cannot tell you

The counts follow the diagnostic code, so they include some claims coded under DC 7913 that are not diabetes, such as vitamin D deficiency, and type I diabetes, which is not on the herbicide list. Secondary counts include only claims the Board marked as secondary to a condition. The groups come from what each decision mentions; a mention is not proof of service or exposure. Historical outcomes, not predictions.

For representatives

  • Prove the qualifying service and the dates first; for a herbicide-exposed veteran, the presumption carries the diabetes.
  • For a Thai air base, show service on the base within the dates; since the PACT Act, no particular job or perimeter duty is needed.
  • Once diabetes is service connected, screen every complication that could be rated on its own: nerves in the legs and arms, kidneys, eyes, circulation and erectile dysfunction.
  • For a veteran without presumptive service, consider whether a service-connected condition such as PTSD led to the diabetes, and get an opinion that explains the chain.

About the data

Board of Veterans' Appeals decisions 2020-2025 (decoder_ring.theories, decoder_ring.presumptions, decoder_ring.secondary_history, bva_cases_v2 lead basis), diagnostic code 7913. Each veteran is counted once per condition, at the best ruling in the decision (granted, then remanded, then denied); grant share = granted / all decided, so a remand counts as not granted. 'More often than usual' compares how often the condition comes up for a group with how often it comes up across all decisions. Groups overlap and are identified from what the decision text mentions; a mention is not proof of service there or of exposure. Historical outcomes, not predictions. Queried October 30, 2026. Every figure in this story is computed from the query results, and the AI-extracted data can contain errors. The figures are fixed as of that date.

Board of Veterans' Appeals decisions show how VA's highest review body applies 38 CFR and weighs evidence on contested claims.

Each one is an appeal: a regional office decided the claim first, and the veteran appealed. So these rates describe the Board, not a veteran's odds at the regional office, where most claims are decided and whose decisions are not public.
