A VA diagnostic code is a four-digit number the Department of Veterans Affairs assigns to each service-connected condition, linking that condition to a specific set of criteria in the VA Schedule for Rating Disabilities. The code controls which symptoms the VA measures, which percentage between 0 and 100 it can assign, and how much tax-free compensation you receive each month. In 2026, monthly payments for a veteran with no dependents range from $180.42 at 10% to $3,938.58 at 100%.1U.S. Department of Veterans Affairs. Veterans Disability Compensation Rates
How the Rating Schedule Is Organized
The rating schedule lives in Title 38 of the Code of Federal Regulations, Part 4, and it groups thousands of conditions by body system.2eCFR. 38 CFR Part 4 – Schedule for Rating Disabilities Musculoskeletal injuries sit in one section, cardiovascular conditions in another, mental health disorders in another, and so on. A knee injury and a shoulder injury are judged against the same musculoskeletal standards. PTSD and depression are evaluated under the mental health criteria.
Within each section, every condition gets its own four-digit code. The codes run from 5000 to 9999, and each spells out what level of impairment justifies a particular percentage.2eCFR. 38 CFR Part 4 – Schedule for Rating Disabilities A veteran with three unrelated conditions may have three codes drawn from three different body-system sections, each evaluated on its own criteria.
How the VA Matches Your Diagnosis to a Code
The process starts with a clinical diagnosis. You either provide medical records or attend a Compensation and Pension (C&P) examination, where a VA examiner documents the condition. The VA then matches that diagnosis to the closest code in the schedule. Tinnitus gets DC 6260. Diabetes gets DC 7913. The assigned code becomes the permanent reference point for that disability unless the diagnosis changes.
Accuracy at this stage matters more than most veterans realize. The code selection controls which symptoms the VA measures and how they translate into a percentage. A wrong code can mean the VA evaluates the wrong symptoms entirely, leaving you underrated. When you read your decision letter, check that the assigned code actually fits your diagnosed condition. The VA is required to tell you which code it used and to explain the criteria that weren’t satisfied for the next higher rating level.3Office of the Law Revision Counsel. 38 USC 5104 – Decisions and Notices of Decisions
How the Code Produces a Percentage
Once a code is assigned, the VA compares your documented symptoms against the criteria written into that code. Ratings run from 0% to 100% in 10-point increments. Each level describes a concrete threshold. Under DC 5260, which covers limited knee flexion, flexion limited to 60 degrees earns 0%, limited to 45 degrees earns 10%, limited to 30 degrees earns 20%, and limited to 15 degrees earns 30%. The examiner measures the joint. The number dictates the rating.
Not every code turns on a physical measurement. Some count the number of incapacitating episodes per year. Some look at frequency of flare-ups. Mental health codes describe occupational and social impairment at each level rather than any physical test. Whatever the code, the evidence is compared directly against the benchmarks it lists.
The Higher-of-Two-Evaluations Rule
When your symptoms fall between two rating levels, the VA is supposed to assign the higher one if the overall disability picture is closer to that level’s criteria.4eCFR. 38 CFR 4.7 – Higher of Two Evaluations Symptoms rarely line up perfectly with one tier. If your knee flexion measures 35 degrees, you sit between the 10% level (45 degrees) and the 20% level (30 degrees). If pain on movement or flare-ups push the picture closer to the higher criteria, the VA should assign 20%.
How Medication Affects the Rating
A 2026 amendment clarified that the VA evaluates disability based on your actual level of functioning under ordinary daily conditions.5Federal Register. Evaluative Rating – Impact of Medication If medication reduces your symptoms, the rating reflects that reduced level. Examiners are not supposed to estimate what the disability would look like without treatment. The practical result: a veteran whose condition is well-controlled on medication may receive a lower rating than someone with the same condition that does not respond to treatment.6eCFR. 38 CFR 4.10 – Functional Impairment
Analogous Codes for Unlisted Conditions
Medical science moves faster than federal regulations. When your condition is not specifically listed in the schedule, the VA rates it by analogy, choosing a listed code whose symptoms and affected body functions most closely match.
The coding format tells you an analogous rating is in play. The VA builds an “unlisted” code by taking the first two digits of the relevant body-system section and ending with 99. That unlisted code goes first, followed by a hyphen and the code whose criteria are actually being used. A code like 6299-6204 means an unlisted condition in the ear/nose system (62XX) is being evaluated using the criteria for DC 6204.7eCFR. 38 CFR 4.27 – Use of Diagnostic Code Numbers The same format works for listed diseases rated by their residual effects. Rheumatoid arthritis rated as ankylosis of the lumbar spine would be coded 5002-5240, with the disease code first and the residual condition code after the hyphen.
The analog choice matters because it controls which criteria apply. If two listed conditions could reasonably serve as analogs, you can argue for the one whose criteria better capture your actual impairment.
One Symptom, One Code: The Pyramiding Rule
The VA cannot rate the same symptom under two different codes. This prohibition, called pyramiding, prevents double-counting.8eCFR. 38 CFR 4.14 – Avoidance of Pyramiding A knee injury that causes both limited motion and instability can support separate ratings under two codes, because those are distinct symptoms. But if pain is already built into the range-of-motion rating, it can’t also justify a separate rating under a different code. The line between legitimate separate ratings and pyramiding is where a lot of claims get complicated, and where errors happen on both sides.
What Each Rating Level Pays in 2026
VA disability compensation is paid monthly and is entirely tax-free.9Internal Revenue Service. Veterans Tax Information and Services For a veteran with no dependents, the 2026 rates are:1U.S. Department of Veterans Affairs. Veterans Disability Compensation Rates
- 10%: $180.42 per month
- 20%: $356.66
- 30%: $552.47
- 40%: $795.84
- 50%: $1,132.90
- 60%: $1,435.02
- 70%: $1,808.45
- 80%: $2,102.15
- 90%: $2,362.30
- 100%: $3,938.58
Veterans rated 30% or higher receive additional compensation for dependents. A veteran rated at 100% with a spouse receives $4,158.16 per month. The jumps between levels are uneven. The difference between 50% and 60% is about $302; the difference between 90% and 100% is over $1,576. That makes higher ratings disproportionately valuable.
A 0% rating still matters. It means the VA has accepted that the condition is service-connected but that current symptoms fall short of the threshold for compensation. That acknowledgment carries 10-point preference in federal hiring, no-cost VA healthcare for the service-connected condition, travel reimbursement for scheduled VA appointments, and commissary and exchange privileges.10Veterans Benefits Administration. VA Benefit Eligibility Matrix It also keeps the door open. If the condition worsens later, you only need to show the increase, not fight the service-connection question again.
Combining More Than One Rating (VA Math)
Veterans with more than one service-connected disability don’t get their percentages added. The VA uses a combined ratings table that applies each successive disability to the remaining non-disabled portion of your capacity.11eCFR. 38 CFR 4.25 – Combined Ratings Table
An example. A veteran with a 60% disability and a 40% disability does not have 100%. Start with the highest rating (60%), then apply the 40% only to the remaining 40% of capacity. Forty percent of 40 is 16, so the combined value is 76%. Add a third disability at 20%, applied to the remaining 24%, and you get another 4.8 points, for 80.8%. Round to the nearest multiple of 10. Final combined rating: 80%.
Rounding happens only once, at the end, after every disability has been combined. Combined values ending in 5 round up.
The Bilateral Factor
When disabilities affect both paired extremities, such as both knees, both shoulders, or one arm and one leg on the same side, the VA applies a bilateral factor. It combines the ratings for the paired extremities, then adds 10% of that combined value before folding the result into the overall combined rating.12eCFR. 38 CFR 4.26 – Bilateral Factor The bilateral factor recognizes that paired disabilities interfere with daily life more than isolated ones.
If the Code or Rating Looks Wrong
If you think the VA assigned the wrong code, applied the criteria incorrectly, or missed a condition, you have three options under the Appeals Modernization Act. Each carries a one-year deadline from the date on the decision letter.13eCFR. 38 CFR Part 20 – Board of Veterans Appeals Rules of Practice
- Supplemental claim. Submit new and relevant evidence the VA didn’t have before. The regional office reviews the whole file again with the new evidence included. This is usually the fastest path when you have additional medical records or a private medical opinion.14eCFR. 38 CFR 3.156 – New and Relevant Evidence
- Higher-level review. A more senior reviewer looks at the same evidence the VA already had. No new evidence allowed. This works best when you believe the original rater misapplied the criteria or made a clear error, including a wrong code.
- Board of Veterans’ Appeals. A Veterans Law Judge reviews the case. You choose one of three tracks: direct review with no new evidence and no hearing, evidence submission with 90 days to add records, or a hearing before the judge.13eCFR. 38 CFR Part 20 – Board of Veterans Appeals Rules of Practice
The one-year clock runs from the date on the decision letter, not the date you read it. Missing the deadline doesn’t end the fight; a supplemental claim with new evidence can still be filed later. But it can affect your effective date and cost months or years of back pay.
