Type 2 diabetes is one of the most claimed conditions for Vietnam-era veterans, because it is presumptive for Agent Orange. But the diabetes rating is only half the story. The nerve, eye, kidney, and heart problems it causes are rated on top, and those are the ratings veterans miss most.
A nexus letter ties it together. Our physicians connect your diabetes to your service, or document the complications that flow from it, in the language the VA expects. One flat fee of $1,500, and the first consultation is free.
How VA Rates Type 2 Diabetes
The VA rates diabetes under 38 C.F.R. § 4.119, Diagnostic Code 7913. The rating climbs with how much treatment your diabetes takes, from diet alone up to insulin with serious episodes and complications. Here is the rule, word for word, then what each level looks like.
"Requiring more than one daily injection of insulin, restricted diet, and regulation of 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 ... 100. Requiring one or more daily injection of insulin, restricted diet, and regulation of activities with episodes ... requiring one or two hospitalizations per year or twice a month visits ... 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."
| Rating | What it generally takes | Monthly pay (approx) |
|---|---|---|
| 100% | More than one daily insulin injection, restricted diet, and regulation of activities, with episodes of ketoacidosis or low blood sugar needing 3 or more hospital stays a year or weekly provider visits, plus weight and strength loss or complications serious enough to rate on their own. | ~$3,939/mo |
| 60% | Insulin, restricted diet, and regulation of activities, with episodes needing 1 or 2 hospital stays a year or twice-monthly provider visits, plus complications too minor to rate on their own. | ~$1,435/mo |
| 40% | Insulin, restricted diet, and regulation of activities (a doctor's order to avoid strenuous activity). | ~$796/mo |
| 20% | Insulin and restricted diet, or an oral medication and restricted diet.Most Common | ~$357/mo |
| 10% | Managed by a restricted diet alone, with no medication. | ~$180/mo |
Pay figures are approximate 2026 rates (effective December 1, 2025) for a single veteran with no dependents. Check VA.gov for current amounts.
How the VA builds a diabetes rating
Diabetes ratings climb with how much treatment your diabetes takes. Each level includes everything below it and adds one more piece. Here is the ladder.
- 1
Diet alone (10%)
Diabetes you keep in check with a restricted diet and no medication.
- 2
Add medication (20%)
An oral medication, or insulin, along with the restricted diet. Most veterans on treatment for type 2 diabetes land here.
- 3
Add regulation of activities (40%)
Insulin and diet, plus a doctor's order to avoid strenuous activity. 'Regulation of activities' is a legal term that needs medical evidence. Your provider has to prescribe limiting your activity; it is not enough that you slow down on your own.
- 4
Add serious episodes and complications (60%)
The 40% picture, plus episodes of ketoacidosis or low blood sugar that need one or two hospital stays a year (or twice-a-month provider visits), plus complications too minor to rate on their own.
- 5
The most severe (100%)
More than one insulin injection a day, diet, and regulation of activities, with episodes needing three or more hospital stays a year (or weekly visits), plus either ongoing weight and strength loss or complications serious enough to rate on their own.
One rule changes the math. Some complications are serious enough to carry their own rating. Those are rated separately and added on top, unless they were used to reach 100% (Note 1). So nerve damage, eye disease, and kidney disease usually stack onto the diabetes rating instead of being folded into it. That is where a diabetes claim grows.
Estimate your diabetes rating (DC 7913)
Diabetes is rated on how much treatment it takes. Answer about your current treatment. This is a rough orientation, not a rating decision, and it does not count the complications, which are often rated separately on top.
Making a VA Disability Claim for Type 2 Diabetes
A VA disability claim for type 2 diabetes needs three things to line up:
A current diagnosis
A diabetes diagnosis backed by lab work (such as your A1c or glucose readings) and your treatment record.
A service connection
Either diabetes that showed up in service, the Agent Orange presumptive path, or a link to another service-connected condition or its treatment.
A medical nexus
A qualified opinion that your diabetes is 'at least as likely as not' connected to your service, or to a service-connected cause.
For most diabetes claims, the presumptive path does the heavy lifting. Type 2 diabetes is on the Agent Orange list. So if you had qualifying exposure, the VA already accepts the link, and you may not need a nexus letter for the diabetes itself. A nexus letter earns its keep on the complications: tying your nerve, eye, kidney, or heart disease back to the diabetes. It also helps on any diabetes claim that is not presumptive. The 'at least as likely as not' standard (a 50% or better chance) comes from the benefit-of-the-doubt rule in 38 U.S.C. § 5107(b), carried out in 38 C.F.R. § 3.102.
How to Connect Type 2 Diabetes to Service
There are a few ways to tie type 2 diabetes to your service. For many veterans the presumptive path is the strongest, because type 2 diabetes is on the Agent Orange list.
Presumptive (Agent Orange)
Type 2 diabetes is an Agent Orange presumptive condition (38 C.F.R. § 3.309(e)). If you had qualifying herbicide exposure, the VA accepts the link to your service.
- Qualifying service. Vietnam, the Korean DMZ, Thailand, and several other locations and time periods can qualify you for presumed Agent Orange exposure.
- No nexus needed. On a presumptive claim you do not have to prove the cause. You still need a current diagnosis and proof of qualifying service.
Direct connection
Diabetes began in service, or was first diagnosed while you served.
- A diagnosis in service. Being diagnosed with diabetes, or showing high blood sugar on labs, while on active duty.
- Onset soon after service. A diagnosis in the years right after service can still support a direct claim with the right medical opinion.
Secondary connection
Another service-connected condition, or its treatment, brought on your diabetes (38 C.F.R. § 3.310).
- Steroid medication. Long-term corticosteroid (steroid) treatment for a service-connected condition can raise blood sugar and bring on diabetes.
- Other service-connected conditions. Some service-connected conditions and the medications that treat them affect how your body handles blood sugar.
Aggravation
You had diabetes before service, and service made it permanently worse.
- Worse during service. Your diabetes progressed, or your treatment had to be stepped up, on active duty, beyond normal change over time.
Secondary Conditions
Diabetes rarely travels alone. It sits at the center of a web of complications, and each one the VA can rate is rated separately and added to your combined rating. This is where most diabetes claims are left on the table.
Diabetes may be secondary to
- Steroid medication. Long-term corticosteroids prescribed for another service-connected condition can raise blood sugar and bring on diabetes.
- Other service-connected conditions. Some service-connected conditions and their treatments change how your body handles blood sugar, which can support a secondary claim.
Conditions that may be secondary to diabetes
- Peripheral neuropathy. Diabetes is the leading cause of nerve damage in the hands and feet, and the most common diabetic complication veterans claim. It is rated separately on its own guide.
- Eye disease (diabetic retinopathy). High blood sugar damages the small vessels in the eyes and can harm vision. Rated on its own.
- Kidney disease (diabetic nephropathy). Diabetes is a leading cause of kidney damage, rated separately under the genitourinary system.
- Heart disease and high blood pressure. Diabetes drives cardiovascular disease. Heart disease and hypertension are each rated on their own.
- Erectile dysfunction. A common diabetic complication, often claimed as a secondary condition.
What to Gather - Evidence Checklist
Gather these before you file or ask for a letter. For diabetes, your treatment record and your complication records do the heavy lifting, because the rating turns on how much treatment it takes and what it has caused.
Frequently Asked Questions
How does the VA rate type 2 diabetes?
Under 38 C.F.R. 4.119, Diagnostic Code 7913. The rating climbs with how much treatment it takes. A restricted diet alone is 10%. An oral medication or insulin plus diet is 20%. Insulin plus a doctor's order to limit your activities is 40%. Serious episodes and complications push it to 60% or 100%. Each level builds on the one before it.
Is type 2 diabetes presumptive for Agent Orange?
Yes. Type 2 diabetes is on the Agent Orange presumptive list (38 C.F.R. 3.309(e)). If you had qualifying herbicide exposure, the VA accepts that your diabetes is connected to your service, so you do not have to prove the cause. You still need a current diagnosis and proof of qualifying service.
What does 'regulation of activities' mean?
It is the legal term for a doctor's order to avoid strenuous occupational and recreational activity because of your diabetes. It is the line between a 20% and a 40% rating, and it needs medical evidence. It is not enough that you have slowed down on your own; your provider has to have prescribed limiting your activity, and it should be in your records.
Can I get separate ratings for my diabetes complications?
Yes, and this is where a diabetes claim grows. The VA rates compensable complications separately and combines them (Note 1 to DC 7913). Peripheral neuropathy in the hands and feet, eye disease, kidney disease, and heart disease are common diabetic complications that each carry their own rating on top of the diabetes, unless they were used to reach a 100% diabetes rating.
Why is my diabetes only rated 20%?
Because 20% covers diabetes controlled by an oral medication or insulin plus diet, which fits most veterans with type 2 diabetes. To reach 40%, you need insulin, diet, and a doctor's order to limit your activities (regulation of activities), backed by medical evidence. The bigger gains usually come from rating the complications separately, not from a higher diabetes number.
Do I need a nexus letter for diabetes?
If your type 2 diabetes is presumptive through Agent Orange, you may not need one for the diabetes itself. Where a nexus letter earns its keep is the complications, tying your neuropathy, eye, kidney, or heart disease back to the diabetes, and any diabetes claim that is not presumptive. That medical opinion is what we write.
Diabetes is rarely just diabetes. Claim what it caused.
Let our physicians prepare a diabetes nexus letter, and document the complications, to meet the VA's evidence standards and support the benefits you earned.
