Folic Acid Deficiency (VA Diagnostic Code 7721)

Understanding Your VA Disability Rating

Folic acid deficiency is a condition rated under VA Diagnostic Code 7721, found in § 4.117 of the VA's rating schedule. It falls within the Hemic and Lymphatic Systems body system — the part of the rating schedule that addresses conditions affecting the blood and related systems.


Available Rating Levels

The VA assigns a disability rating based on how the condition presents and what type of treatment it requires. For folic acid deficiency, there are two rating levels:

10% Rating

Assigned when the condition requires continuous treatment with high-dose oral supplementation.

0% Rating

Assigned when the condition is asymptomatic or requires treatment only by dietary modification.


What the VA Looks For

When rating folic acid deficiency, the VA focuses on the level of treatment your condition requires:

  • Whether continuous, high-dose oral supplementation is needed — this supports the 10% rating level.
  • Whether the condition is asymptomatic, or can be managed through dietary modification alone — this corresponds to the 0% rating level.

These distinctions come directly from the rating criteria under § 4.117 for Diagnostic Code 7721. Your specific rating depends on how your condition and treatment needs align with the criteria above.

These criteria are a rendering of § 4.117, diagnostic code 7721. The official version is the one that governs your rating.
