What 17314 covers
During Mohs surgery, the surgeon removes another thin layer from the mapped surgical site after microscopic review shows residual tumor at a margin. The tissue is oriented and mapped, processed for immediate microscopic examination, and assessed so the surgeon can target further removal while preserving uninvolved tissue. Dermatologic surgeons and other physicians trained in Mohs technique commonly perform this service in office-based skin cancer surgery settings.
Use 17314 after the initial Mohs stage code 17313 for a lesion on the trunk, an arm, or a leg. It represents an additional stage, not another lesion or simply another tissue block. Documentation should identify the operative site and stage and support further excision through the mapping and microscopic findings. Report 17313 for the initial stage and 17314 for each additional stage; qualifying blocks beyond the stage allowance are reported separately with 17315. CMS classifies 17314 as an add-on: it must be billed with a primary procedure and is paid within that procedure’s global period.

17314 billing questions
When should 17314 be used instead of 17313?
Use 17313 for the initial Mohs stage on the trunk, an arm, or a leg. Use 17314 for each additional stage required after that initial stage.
Can 17314 be billed by itself?
No. It is an add-on code and must be reported with the primary Mohs procedure, typically 17313 for these body sites.
Is 17314 reported for each tissue block?
No. It represents an additional stage, not a count of blocks. Code 17315 addresses additional blocks beyond the applicable stage allowance.
What documentation supports an additional stage?
Document the Mohs site and stage, the mapped tissue and microscopic margin findings, and why further tissue removal was needed.
Does 17314 have a separate global period?
No separate global period is assigned in the CMS facts for this code. CMS identifies it as an add-on paid within the primary procedure’s global period.
