§ 4.117 Schedule of ratings—hemic and lymphatic systems.

Folic acid deficiency

A condition where the body lacks sufficient folic acid, a vitamin needed to produce healthy red blood cells.

What the rating means

VA rates folic acid deficiency under diagnostic code 7721 in the hemic and lymphatic systems schedule. There are two possible ratings: 10% and 0%.

You receive a 10% rating when your condition requires continuous treatment with high-dose oral supplementation. You receive a 0% rating when you have no symptoms or when your condition is managed only by changing what you eat, without medication.

The key difference between the two levels is whether your treatment goes beyond diet alone. If your provider has prescribed ongoing high-dose folic acid supplements, that points toward the 10% level. If your folic acid deficiency produces no symptoms and requires only dietary adjustments, the 0% level applies.

Evidence that helps

To support a 10% rating, evidence should show that you are on a continuous regimen of high-dose oral folic acid supplementation prescribed by a medical provider. Treatment records, pharmacy records, or prescription printouts that document the dose and the ongoing nature of that treatment are directly relevant. A provider's notes explaining why dietary changes alone are not enough to manage your condition can also help show this level of need.

To reflect the 0% level, records would show either that you have no current symptoms or that your condition is controlled through diet alone, with no prescription supplementation required. If you believe your symptoms or treatment requirements affect your work or daily life in ways your records do not fully capture, a personal statement or a statement from someone who knows you can help give VA a fuller picture of your day-to-day situation.
