Summary
Illinois establishes billing guidelines for monkeypox testing using CPT code 87593 at a Medicaid rate of $30.79, effective July 26, 2022. Monkeypox vaccines are provided free from the federal government with no separate administration fees - only minimal office visit charges when vaccination is the sole purpose of visit.
Action Required
Immediately: Update billing system to use CPT code 87593 for monkeypox virus testing at $30.79 for Illinois Medicaid patients. Do not bill for monkeypox vaccine costs (free from federal government). For vaccination-only visits, bill minimal office visit CPT code instead of separate administration fees. Update encounter forms to reflect these billing rules.
