How to Read the Code Sheet in Your VA Rating Decision

What the code sheet is

A VA rating decision usually has two parts: the narrative letter that explains the outcome in prose, and the code sheet — a compact technical page listing each service-connected condition, the diagnostic code assigned to it, the evaluation percentage, the effective date, and any special notations such as static evaluations or scheduled future examinations.

The narrative tells you what VA decided. The code sheet tells you how it was recorded. Most of the errors that matter — wrong diagnostic code, missing bilateral factor, an effective date that costs months of back pay — appear on the code sheet in plain form.

Line by line

Diagnostic code

Each condition is assigned a four-digit code from the rating schedule in 38 CFR Part 4. A hyphenated code such as 5299-5237 means the condition is not separately listed in the schedule and is being rated by analogy under 38 CFR § 4.20. The first four digits identify the body system, the second four identify the criteria actually applied.

If the criteria being applied do not match the way the condition actually limits you, that is a rating-by-analogy issue worth reviewing.

Evaluation percentage

The percentage reflects the criteria in the diagnostic code, not the severity a treating provider might describe in general terms. For orthopedic conditions the percentage is driven by measured range of motion; for mental health conditions it reflects occupational and social impairment under 38 CFR § 4.130.

Effective date

This is the single most valuable line on the sheet. The effective date controls how far back compensation is paid. Common problems include a date set to the claim receipt date when an Intent to File was on record, or a date that ignores evidence showing entitlement arose earlier under 38 CFR § 3.400.

Combined evaluation

The combined figure is not the sum of the individual percentages. It is calculated under the table in 38 CFR § 4.25 and then rounded to the nearest ten. The bilateral factor in 38 CFR § 4.26 adds ten percent of the combined value of disabilities affecting both arms or both legs before the rest of the calculation.

What to check first

• Is every claimed condition listed, or was one deferred and never decided?
• Does each diagnostic code match the condition and its actual functional limits?
• Are effective dates consistent with any Intent to File or earlier claim in the record?
• Was radiculopathy or another neurological component rated separately, or folded into the spine rating?
• Does the bilateral factor appear where both limbs are involved?
• Is a future examination scheduled on a condition that should be static?

Getting a copy

The code sheet is not always mailed with the narrative decision. It can be requested from VA or found in the claims file, which is obtained by requesting the C-file. Reviewing the code sheet and the evidence VA actually cited is the first step in deciding whether a decision belongs in a Higher-Level Review lane (a legal or record error) or a Supplemental Claim lane (missing evidence).

Why this matters

Nothing on the code sheet is a promise about any particular case. Whether an error exists, and what VA does about it, is decided by VA under the applicable regulations. What the code sheet gives you is a factual, verifiable place to start — instead of guessing at why a decision came out the way it did.
