Billing tips

Document high complexity medical decision-making by addressing at least two of three elements: extensive diagnosis/management options, extensive data review, or high risk of complications
Impact: Proper MDM documentation justifies 99223 vs 99222 (saves $46+ per encounter) or 99221 (saves $88+ per encounter)
Bill 99223 only once per admission per physician; subsequent days require 99231-99233
Impact: Billing 99223 twice during same admission results in 100% denial of second claim ($167.23 loss)
When time-based documentation is used (50%+ counseling/coordination), document total floor time and time spent in counseling with content summary
Impact: Time-based coding requires 75+ minutes; insufficient documentation may force downcoding to 99222, reducing payment by approximately $46
Verify admission status (inpatient vs observation) before claim submission as this affects hospital facility billing but not professional fee
Impact: Professional payment remains $167.23 for both settings, but incorrect POS code causes claim routing delays
Do not bill 99223 with critical care codes 99291/99292 on same date unless services are clearly separate and modifier 25 is appended
Impact: Unbundling violations result in denial of 99223 ($167.23 loss) as critical care is higher valued
For split/shared visits with NPPs in hospital setting, ensure physician performs substantive portion and documents accordingly per 2022 split/shared guidelines
Impact: Improper split/shared documentation may require billing under NPP at 85% rate ($142.14 vs $167.23), losing $25.09 per encounter
