Dermatology Billing · Texas

Dermatology billing and revenue cycle for Texas providers.

Texas operates 659 dermatology provider organizations registered in NPPES, representing 7.4 percent of the U.S. dermatology billing footprint. Texas is a major dermatology billing market. Dermatology revenue cycle requires precision: lesion removal sizing, Mohs stage billing, cosmetic vs medical separation, modifier 25 discipline, and biologic PA management. Texas dermatology practices need RCM that handles this granularity reliably.

What good dermatology billing execution looks like for Texas providers.

The Texas dermatology billing market has its own quirks. Here is the operating discipline we install on every Texas 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). Texas 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 separationTexas 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 specimensTexas 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.
