Summary
Maryland Medicaid transitioned from state-specific procedure codes to national HCPCS codes for oxygen and respiratory equipment billing to comply with HIPAA requirements. The change also allows direct billing for certain low-cost items without prior authorization.
Action Required
By October 1, 2003: Billing teams must update all oxygen and respiratory equipment claims to use the new HCPCS codes listed in the fee schedule instead of previous state-specific codes. Update billing system with new maximum allowable costs for purchase and rental charges. Review which low-cost items no longer require prior authorization before billing Maryland Medicaid.
