What the words mean in your records

High-dose oral supplementation

Those words are the 10 percent line. The line says continuous treatment. It does not name a dose, a brand, or a laboratory cutoff.

Dietary modification is the 0 percent line

The 0 percent line is “Asymptomatic or requiring treatment only by dietary modification.” It does not end with a period.

No note on this row

Nothing after the 0 percent line is labeled as a DC 7721 note in the 2026-10-01 table.

Secondary conditions and presumptions

Section 3.309 does not contain “folic,” “folate,” or “7721.” This page does not add DC 7721 to a presumptive row.
