Initial Inpatient Consultation - High Complexity
Code Level: High complexity initial inpatient/observation consultation
Typical Time: 80 minutes (or more, if using time-based method)
2025 Medicare Reimbursement: Payer-dependent (Medicare no longer pays consult codes; use 99221-99223 for Medicare)
Requirement Method: Time-based OR High-Complexity MDM (choose one)
⚠️ CRITICAL QUALIFICATION REQUIREMENTS
Setting & Timing Requirements

NOTE (Payer Policy):
- Many commercial payers still recognize 99255 and other consult codes
- Medicare (and some commercial payers) require you to report initial hospital/OBS codes 99221-99223 instead of 99255
