In simple words: This code is used for billing a single dose of a vitamin, mineral, or trace element taken by mouth, when there isn't a more specific code.

This code represents a single vitamin, mineral, or trace element taken orally, per dose, when not otherwise specified by another HCPCS code.

Example 1: A patient takes a single oral dose of vitamin D3 supplement, and no other specific HCPCS code exists for this supplement., A patient receives a single oral dose of an iron supplement in the form of ferrous sulfate, and there is no other specific HCPCS code for this form of iron., A patient is administered a single oral dose of zinc supplement during a clinic visit, and a specific HCPCS code for this supplement is unavailable.

Documentation should specify the specific vitamin, mineral, or trace element administered, the dosage, the route of administration (oral), and the medical necessity for the single dose.
