Billing tips

Time-based billing available: If total time on date of encounter exceeds 55 minutes (up to 84 minutes), use 99222. Beyond 84 minutes, upgrade to 99223 for $186.19 reimbursement
Impact: $60.69 additional reimbursement when upgrading to 99223 based on time documentation
Document MDM elements precisely: Ensure documentation includes number/complexity of problems addressed, amount/complexity of data reviewed, and risk of complications. Two of three MDM elements must meet moderate level
Impact: Prevents downgrades to 99221 ($89.34), which would lose $36.16 per encounter
Bill only once per admission: 99222 is for initial hospital/observation care. Subsequent days require 99231-99233 codes. Billing 99222 twice in same admission results in denial
Impact: Prevents 100% denial and potential audit flags for duplicate billing
Separate observation from inpatient admission: If patient status changes from observation to inpatient on same calendar day, bill only one initial service code (99222). Do not bill both observation and inpatient admission codes
Impact: Avoids duplicate billing denials and recoupment of $125.50
Document face-to-face time when using time: If using time as basis for code selection, document start/stop times and total time spent on date of encounter, including non-face-to-face coordination
Impact: Supports code selection on appeal and prevents downgrades during audits
Verify place of service code: Use POS 21 for inpatient hospital or POS 22 for outpatient hospital/observation. Incorrect POS can trigger automatic denials
Prevents administrative denials requiring resubmission and payment delays of 30-60 days
