What good dermatology billing execution looks like for Washington providers.

The Washington dermatology billing market has its own quirks. Here is the operating discipline we install on every Washington engagement.

  1. Lesion removal coding by size and methodDermatology lesion removal billing requires precise capture of lesion size, anatomic location, benign vs malignant pathology, and removal method (excision, destruction, shave). Washington derm practices need coders who can read op notes accurately.
  2. Mohs surgery billing and stage trackingMohs micrographic surgery bills per stage with specific CPT codes (17311-17315). Accurate stage tracking and same-day reconstruction coding are essential.
  3. Cosmetic vs medical service separationWashington dermatology practices often mix cosmetic (cash pay) and medical (insurance) services. Clean separation in scheduling, billing, and patient consent prevents claim disputes and audit risk.
  4. Modifier 25 discipline for E/M + procedureSame-day E/M plus procedure (biopsy, destruction, injection) is daily reality in dermatology. Modifier 25 must be defensible with clear separate E/M documentation.
  5. Path lab billing for in-house specimensWashington dermatology practices with in-house pathology need accurate 88305 / 88312 billing, professional + technical component awareness, and CLIA compliance.
  6. Specialty drug PA for biologics (Dupixent, Cosentyx, etc.)Dermatologic biologics carry significant PA burden and specialty pharmacy coordination. PA automation reduces patient access delays significantly.
