Billing tips
Choose between time-based (40-54 minutes total time) or MDM-based billing for 99215; time-based is often easier to document and defend in audits
Impact: Proper time documentation can increase revenue 89% compared to undercoding to 99214 ($175.64 vs $93.20 difference of $82.44 per encounter)
Document total time on date of encounter including face-to-face and non-face-to-face activities (reviewing records, ordering tests, care coordination, documentation) performed by the billing provider
Impact: Capturing all eligible time activities can push 35-minute encounters into 99215 territory, worth $44.97 more than 99214
For MDM-based billing, ensure documentation clearly shows high complexity: extensive number/complexity of problems (1 chronic illness with severe exacerbation or 2+ chronic with exacerbation) AND extensive data review AND high risk management
Impact: Meeting 2 of 3 MDM elements at high level supports 99215; incomplete MDM documentation causes an estimated 40% of 99215 downgrades to 99214
Use modifier 25 appropriately when performing same-day procedures; document that E&M was significant and separately identifiable from procedure
Impact: Proper modifier 25 use can preserve the full $175.64 payment that would otherwise be bundled and lost
Review non-facility vs facility rates when billing for hospital-based clinic visits; ensure place of service code matches actual location
Impact: Incorrect POS coding can result in $36.87 overpayment (non-facility $175.64 vs facility $138.77) triggering recoupment
Establish consistent templated documentation that captures all 2021 E&M guideline elements including total time spent, MDM components, and clear statement of complexity level
