How to appeal a Skin Biopsy & Pathology (TC/26 Split) denial
These denials cluster around the technical/professional (TC/26) split and biopsy add-on units, when the payer pays the global or one component and denies the other, or caps the number of biopsies.
Common code: CPT 11102-11107 (biopsy), 88305 (path, with modifier TC or 26 when split)Why it gets denied
- The professional (26) or technical (TC) component was billed to a payer that only recognizes the global service
- Additional biopsy units (11103/11105/11107) exceed frequency or MUE limits
- Two entities billed overlapping components and one was denied as duplicate
- The biopsy is bundled with a same-day destruction or excision of the same lesion
What overturns it
- Confirm whether the payer wants global or split billing and rebill the correct component with TC or 26
- Document each biopsy site and technique so add-on units are supported
- Reference the other entity's claim to separate professional from technical and clear the duplicate flag
- Show the biopsy was a distinct diagnostic service, not a component of the same-day procedure
Worth appealing? The path professional read is small per unit but high-volume, and TC/26 confusion silently underpays it. Reconciling billed against paid components surfaces recoverable dollars that never look like a denial.
