Summary
Pennsylvania Medicaid is replacing local procedure code W0500 with national procedure codes for provider mileage billing effective December 1, 2005. This change is required for HIPAA compliance and affects all providers who bill for mileage related to service provision.
Action Required
By December 1, 2005: Billing team must stop using local procedure code W0500 for provider mileage claims. Reference the attached crosswalk spreadsheet to identify the correct national procedure code replacement. Update billing system to use national codes for all services rendered on or after December 1, 2005. Continue using W0500 only for services rendered on or before November 30, 2005. Failure to use appropriate national procedure codes will result in inappropriate claim payment or claim denial.
