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.
