Dermatology Bill Explained

What this document usually means

A dermatology bill covers your visit to a skin doctor and any procedures performed. A routine skin exam is billed as an E/M office visit, but if the dermatologist performed a biopsy, removed a lesion, or administered a treatment during the visit, those procedures generate separate charges. A biopsy also triggers a pathology charge from the lab that analyzes the tissue sample.

Common dermatology procedure codes include shave biopsies, punch biopsies, destruction of lesions (using liquid nitrogen), and excisions. Each has its own CPT code and price point.

The first things to check

Confirm the date and provider name. Count the number of procedures listed and compare them to what you remember happening during the visit. If the dermatologist biopsied two spots, you should see two biopsy charges. Check whether you also received a separate bill from a pathology lab.

Verify whether the visit was coded as a preventive skin screening or a diagnostic visit, as some plans cover preventive screenings at no cost but apply cost-sharing to diagnostic visits.

Common reasons this letter feels confusing

A visit that felt like one appointment can generate multiple charges because the exam, biopsy, and pathology are each billed separately. It is also confusing when a preventive skin screening turns into a diagnostic visit because the dermatologist found something that needed evaluation.

Insurance classification of cosmetic versus medical procedures creates additional confusion. Removal of a suspicious mole is medical, but removal of a benign skin tag may be considered cosmetic and not covered.

What to do before you pay or respond

Compare the bill to your EOB. If the visit was supposed to be preventive but was billed as diagnostic, ask the dermatologist's office whether the coding can be corrected. If a biopsy result came back benign, the initial biopsy is still a covered medical service.

If you received a pathology bill from an out-of-network lab, ask the dermatologist's office why that lab was chosen and whether the claim can be sent to an in-network lab for reprocessing. You did not have the ability to choose the lab yourself.
