UCR 304: Prior Authorization Codes, Billing for DME Supplies, and Can You Trust AI?

September 11, 2026

 In this episode, Scott and Mark Painter are joined by Dr. John Lin to tackle several practical coding and reimbursement questions from the urology community. They discuss whether there is a right number of CPT codes to include on a prior authorization, when catheter and other DME supply A-codes can—or cannot—be separately billed, and how those rules apply to Foley catheter changes and BCG instillations. The conversation also explores the growing use of AI for coding research and why an answer that sounds authoritative may still be wrong. The key takeaway: use AI as a tool, but understand the fundamentals, ask the right follow-up questions, and always verify important coding answers against primary sources.
