Specialty billing

Dermatology billing

We code dermatology to your payer rules, not a generic template, handling lesion procedures, Mohs staging, biopsies, and the medical-versus-cosmetic line the way each plan expects.

Where claims slip

Billing considerations for dermatology

Common places dermatology revenue leaks. We code each of these to your payer rules, not a one-size-fits-all template.

01

Lesion procedures are counted by units and size, so unit and modifier errors directly change reimbursement.

02

Mohs surgery is staged, and each stage and the margin documentation must be coded correctly.

03

Biopsy, shave, and excision are distinct services that are easy to confuse.

04

Phototherapy units are calculated by treatment and body area.

05

The medical-versus-cosmetic distinction creates compliance risk when a cosmetic service is coded as medical.

Common questions

Dermatology billing, answered.

How do you handle lesion unit counting?

We code lesion destruction and excision by the documented count and size, with the correct units and modifiers, since those details drive the reimbursement.

Do you bill Mohs surgery by stage?

Yes. We code each Mohs stage and the associated documentation, so the staged work is captured accurately rather than under one flat code.

How do you handle cosmetic versus medical procedures?

We code medical procedures to payer rules and keep cosmetic services separate, which reduces compliance risk and avoids billing a cosmetic service as covered care.
