Dermatology practice adds $286K by correcting Mohs and pathology coding

A busy dermatology practice suspected undercoding in Mohs stages, repairs and pathology but lacked a defensible chart-level measurement.

The situation

Repair complexity and additional Mohs stages were not consistently captured from operative documentation.

Pathology and office-visit combinations generated modifier errors and preventable payer requests for records.

What we did

  1. 01

    We audited charts by provider and procedure family, then quantified undercoding and compliance exposure separately.

  2. 02

    Coder guidance linked each correction to the operative note elements required to support it.

  3. 03

    Templates and pre-bill edits were updated so missed stages, repairs and modifier combinations surfaced before submission.

The result

  • The audit identified a $286K annualized revenue opportunity from work already documented.
  • Coding accuracy reached 98.8% on follow-up sampling.
  • Modifier-related denials and records requests fell 67% in four months.

"The audit was practical: every finding showed the chart, the code, the dollar impact and the exact correction."
