I don't have any good news to report. We have billed single applications: One to Medicare (Palmetto, S. Calif.), and one to UHC. Both have been denied. Neither was pre-authorized, which was a mistake. What about using CPT codes from the section, "Destruction, Benign or Pre-Malignant Lesions” to describe the chemical peel process for AK procedures? For instance, look at CPT 17000, as this category includes chemosurgery, the destruction of tissue by chemical means for therapeutic purposes.
