Billing tips
Verify exact age at time of service - patient must be 29 days through 23 months; use 99468 for neonates ≤28 days and 99291/99292 for children ≥24 months
Impact: Age documentation errors account for 30-40% of denials; wrong code selection can mean $200-400 reimbursement difference
Bill only once per calendar day regardless of time spent; 99471 is a per-day service covering all critical care on initial day, not time-based like 99291
Impact: Prevents duplicate billing denials and potential fraud flags; protects full $738.47 payment
Document that patient meets critical care criteria with specific vital sign instability, need for life-sustaining interventions, and high probability of imminent deterioration
Impact: Missing critical care justification is the #1 cause of downcoding to lower-level hospital codes (99221-99223), resulting in $400-500 payment loss
Do not separately bill procedures bundled into 99471 including vascular access, ventilator management, chest tube placement, invasive monitoring, gastric intubation, and temporary pacing
Impact: Unbundling triggers audits and recoupment; integrated procedures already account for 5.75 PE RVUs in the payment
Use 99472 for each subsequent day of critical care for the same patient; 99471 is strictly for the initial day only
Impact: Billing 99471 on subsequent days will be denied; proper sequential coding ensures continued payment at $738.47 per day
Ensure physician personally documents critical care time spent, interventions performed, patient status assessments, and management decisions - cannot rely solely on nursing notes
