Dermatologic surgery

About 17312: Mohs surgery additional stage, specified sites

Reports an additional Mohs surgery stage for a lesion on the head, neck, hands, feet, or genitalia when microscopic examination shows tumor remains.

A Mohs surgeon, commonly a dermatologist, removes and maps another thin layer of tissue after the initial stage. The tissue is processed and examined microscopically so the surgeon can identify whether tumor remains at the margins and whether another stage is needed. Code 17312 is for an additional stage at the head, neck, hands, feet, or genitalia; the first stage is reported separately with the appropriate primary Mohs code. Mohs is commonly performed in an office surgical setting.

Report 17312 for each additional stage after the first, rather than for each tissue block within a stage. The operative record should identify the lesion and site, the stage sequence, tissue mapping and microscopic findings, and the reason another layer was taken. A stage may include up to five tissue blocks; additional blocks are addressed with 17315. As an add-on code, 17312 is billed only with a primary procedure and is paid within that procedure's global period.

17312 billing questions

When should 17312 be used instead of 17311?

Use 17311 for the first Mohs stage on the head, neck, hands, feet, or genitalia. Report 17312 for each additional stage at one of those sites.

Is 17312 billed per tissue block?

No. It represents an additional stage, which can include up to five tissue blocks. Code 17315 addresses additional blocks beyond that amount.

Can 17312 be reported by itself?

No. It is an add-on code and must be billed with the primary Mohs procedure for the lesion.

Which additional-stage code applies to a lesion on the trunk or an extremity?

Use 17314 for an additional stage on the trunk, arms, or legs. Code 17312 is for additional stages on the head, neck, hands, feet, or genitalia.

What documentation supports an additional-stage unit?

The operative record should show the lesion site, the additional stage performed, the tissue map and microscopic findings, and the reason the surgeon continued.
