## 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.
