Billing tips
Document exact start and stop times for all CCM activities, not just duration totals, and maintain detailed activity logs showing incremental 20-minute periods
Impact: Reduces audit risk by 70% and supports multiple units of 99437; each properly documented 20-minute increment generates $57.58
Bill 99437 only after first reporting primary CCM code (99490, 99491, or 99439) in the same calendar month; cannot be billed as standalone
Impact: Prevents automatic denial; 99437 generates zero payment if primary CCM code not on same claim or previous claim same month
Use EHR time-tracking features or dedicated CCM software to automatically aggregate clinical staff and physician time throughout the month
Impact: Captures 15-25% more billable time that would otherwise be missed; can add 1-2 additional units of 99437 per complex patient monthly
Bill 99437 for each additional 20 minutes beyond the threshold of the primary code (e.g., if 99490 covers first 20 min, bill 99437 at 40, 60, 80 minutes)
Impact: Maximum reimbursement: patients requiring 80 minutes generate $115.16-$172.74 in add-on revenue (2-3 units of 99437)
Ensure consent for CCM services is obtained and documented before the first billing month and is renewed annually per CMS requirements
Impact: Missing consent triggers immediate denial of all CCM codes including 99437; impacts entire month's revenue ($57.58+ per occurrence)
Coordinate billing among multiple providers to ensure only one practice bills CCM codes per patient per month to avoid duplicate billing edits
Impact: Prevents claim denials and recoupment; duplicate billing results in 100% payment reversal plus potential fraud investigation
Common denials
Primary CCM code (99490/99491/99439) not billed in same calendar month, causing add-on code rejection
How to appeal: Submit corrected claim with both primary CCM code and 99437 on same claim or provide documentation showing primary code was paid earlier in month. Include remittance advice showing primary code payment and detailed time logs supporting add-on service.
Insufficient documentation of 20-minute time increment, with time logs showing less than full 20 additional minutes beyond primary code threshold
How to appeal: Provide detailed time log with specific dates, times, staff members, and activities performed. Highlight cumulative time calculations showing clear 20-minute increments. Submit care plan, communication records, and medication management documentation supporting time spent.
Missing or expired patient consent for chronic care management services
How to appeal: Submit signed and dated consent form showing it was obtained before service date. If consent was verbal, provide documentation of verbal consent in medical record with date obtained. For expired consent, obtain new consent and resubmit for services after new consent date only.
Duplicate billing with another provider who already billed CCM codes for same patient in same month
How to appeal: Coordinate with other provider to determine who provided majority of CCM services. Provider who did not provide services should withdraw claim. Submit documentation showing your practice was designated primary CCM coordinator and other provider agrees to withdraw their claim.
