Billing tips
Document total time spent on the date of encounter when using time-based billing (30-39 minutes qualifies for 99214)
Impact: Time-based billing often easier to defend in audits than MDM; can increase coding level appropriateness by 15-20% compared to history/exam-based coding
Ensure medical decision making meets moderate complexity: either moderate number/complexity of problems addressed, moderate data reviewed, or moderate risk
Impact: Undercoding to 99213 costs $39.38 per visit; with 20 patients per day, this equals nearly $200,000 annually in lost revenue
Bill in non-facility settings whenever possible to capture the higher rate
Impact: Non-facility rate of $125.18 versus facility rate of $93.80 represents $31.38 (33%) higher reimbursement per encounter
When billing modifier 25 with a procedure, ensure documentation clearly shows the E&M was separately identifiable and above the usual pre/post-service work
Impact: Proper modifier 25 documentation prevents denial of the $125.18 E&M payment; improper use can trigger Recovery Audit Contractor review
For chronic care management, document all conditions addressed and medications reviewed to support moderate complexity MDM
Impact: Prescription drug management alone can support moderate MDM; documenting 3+ prescription drugs reviewed can justify 99214 over 99213
Verify patient established status (seen by same provider or group within past 3 years) to avoid new patient code confusion
Impact: Using 99214 for new patient is a coding error; correct new patient code 99204 pays $183.19, avoiding $58.01 underpayment and compliance risk
