Coding

Coding complexities we watch closely

Modifier usage, documentation rules, and specialty-specific payer edits.

Complexity checklist
  • Lesion excision coding based on excised diameter and location.
  • Mohs surgery coding, including the surgical component and pathology services.
  • Correct use of modifiers for multiple procedures (e.g., -59, -51, -XE).
  • Distinguishing between destruction (e.g., 17000 series) and excision (e.g., 11400 series) codes.
Denial triggers

Incorrect measurement or coding of lesion size.

Missing documentation for medical necessity, especially for cosmetic-adjacent procedures.

Unbundling of Mohs surgery components.

Lack of prior authorization for specialty drugs.

Bundling issues with multiple procedures performed on the same day.
