Audit Defense & Denial Intelligence
Research-based denial patterns from OrbDoc Bill Analyzer
1. Additional complex CCM time not documented or cumulative time below 90-minute threshold
Common99489 (additional 30 minutes complex CCM) requires 99487 billed same month AND additional 30+ minutes documented beyond 99487's 60-minute requirement. Total cumulative monthly time must be 90+ minutes to bill both codes. Cannot bill 99489 standalone or without 99487 same month.
Common Causes
- • Billed 99489 without 99487 same month - denied as standalone
- • Total monthly time 75 minutes - covers 99487 (60 min) but only 15 extra, need 30 for 99489
- • Time spread across multiple months, not aggregated within single month
Resolution Strategy
Document cumulative monthly time showing 90+ minutes: time log with dates, activities, duration for entire month. Ensure 99487 billed same month before billing 99489. If total time 60-89 minutes, rebill as 99487 only (drop 99489). If time truly 90+ minutes, appeal with detailed time log showing complex CCM activities across full month.
