Denial patterns, documentation standards, and appeal workflows built for how each specialty actually gets paid. Every guide grounded in primary sources: CMS, AMA, CARC/RARC master lists, and current federal regulations.
Denial rates run 15-25%, roughly triple general medicine. Learn the 2026 parity landscape, top denial codes, and how to win 80%+ of external appeals.
Modifier strategy (25, 59, X modifiers), cosmetic vs medical necessity documentation, and the bundling rules that drive denials in dermatology practices.
The 8-minute rule mapped to timed CPT codes, plan of care documentation that survives NCCI edits, and Medicare therapy threshold strategy.
Implant billing (pass-through vs packaged), multiple procedure reductions, POS 24 vs POS 22 coding, and the CARC 45 problem that drains ASC revenue.
Generalist billing treats denials as clerical errors to rework and resubmit. Specialty billing treats them as signals. A denied 90837 is not a coding error, it is a clinical necessity dispute. A denied ASC implant is not a missing modifier, it is a pass-through classification gap. The specialty determines the playbook.
