Billing tips
Document all three complexity factors: clinical presentation with evolving symptoms, clinical decision-making affecting 3+ variables, and multiple treatment options considered
Impact: Proper documentation prevents $23-31 downcoding to 97161 and supports the full $98.01 reimbursement
Include objective measures and standardized tests (e.g., Berg Balance Scale, Timed Up and Go, gait speed) to demonstrate moderate complexity
Impact: Objective outcome measures strengthen medical necessity and reduce audit risk by 40-60% according to OIG reports
Bill 97162 only once per discipline per episode of care; subsequent re-evaluations should use 97164
Impact: Incorrect repeat billing of 97162 triggers automatic denials; 97164 pays $64.27, and proper coding avoids $33.74 recoupment
Ensure the evaluation takes approximately 30 minutes face-to-face; document start and end times to support time-based intensity
Impact: Significant time variance (under 20 or over 40 minutes) may trigger audits or downcoding requests
Never bill 97162 on the same day as 97161 or 97163; only one evaluation code per discipline per day is reimbursable
Impact: Duplicate evaluation billing results in 100% denial of the second code and potential fraud investigation
Use the GP modifier consistently on all Medicare PT claims; verify payer-specific modifier requirements for commercial insurers
Impact: Missing GP modifier causes immediate Medicare denial of the entire $98.01; some MAC contractors auto-deny without manual review opportunity
