Billing tips
Document the exact start and stop times for all care management activities to substantiate the required 30 minutes; include dates, durations, and specific activities performed by each team member
Impact: Prevents denials worth $80.87 per claim; time-tracking errors are the #1 audit finding for PrCM codes
Bill only once per calendar month and ensure patient has provided written consent before initiating services; maintain signed consent forms documenting patient agreement to cost-sharing
Impact: Avoids 100% claim denial and potential recoupment; Medicare requires documented consent prior to first billing
Do not bill 99424 in the same month as CCM codes (99490, 99491, 99439), transitional care management (99495-99496), or other care management services that bundle similar activities
Impact: Prevents bundling denials and recoupment of $80.87-$160+ per month in duplicate service payments
Clearly identify and document the single serious chronic condition being managed as the principal focus; the condition must meet criteria for high risk of morbidity/mortality
Impact: Strengthens medical necessity documentation; reduces audit risk estimated at 15-20% for vaguely documented PrCM claims
Use 99425 for each additional 30 minutes beyond the first 30 minutes in the same month to capture all compensable time
Impact: Captures additional $72.13 per 30-minute increment; practices often lose $200-500/month by not billing add-on code
Verify the patient has not been billed for PrCM by another provider in the same month; only one practitioner can bill per calendar month
Impact: Prevents claim denials and compliance issues; duplicate billing can trigger $80.87 recoupment plus potential fraud investigation
Common denials
Insufficient time documented - fewer than 30 minutes of qualifying care management activities recorded in the calendar month
How to appeal: Submit detailed time logs showing date, duration, staff member, and specific activity for each care management task; ensure total exceeds 30 minutes of qualifying non-face-to-face time excluding activities on same day as E/M visits
Missing or inadequate patient consent documentation for cost-sharing responsibilities
How to appeal: Provide signed and dated consent form showing patient was informed of PrCM services, cost-sharing obligations, and right to decline; consent must be obtained before first billing and documented in medical record
Service billed in same month as conflicting care management code (CCM, TCM, RPM, or another provider's PrCM)
How to appeal: Review billing records to confirm no overlapping services; if services are truly distinct and non-duplicative, provide detailed explanation of why both codes are medically necessary with supporting documentation; often requires withdrawal of one claim
Medical necessity not established - documentation fails to support single serious chronic condition requiring principal care management level of service
How to appeal: Submit comprehensive clinical documentation demonstrating severity of chronic condition, risk of exacerbation/hospitalization, complexity of medication regimen, and necessity of intensive care coordination; include care plan showing comprehensive management approach for the principal condition
