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 the 2026 KX modifier threshold ($2,480) strategy.
Implant billing (pass-through vs packaged), POS 24 vs 22, multiple procedure reductions, and the CY 2026 OPPS/ASC rule changes (302 new covered procedures).
Intravitreal injection laterality (67028 with J-codes), cataract global periods, premium IOL split-billing (V2632), and 2026 NCCI Chapter 8 bundling rules.
Global surgical period modifiers (24, 58, 78, 79), joint injection billing (20610, 20611), fracture care globals, and assistant surgeon payment policy indicators.
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.
