12VAC30-80-300. Medicare equivalent of average commercial rate.

Physician supplemental payment amounts shall be calculated using the Medicare equivalent of the average commercial rate (ACR) methodology prescribed by CMS. The following methodology describes the calculation of the supplemental payment. To compute the ACR by commercial payers, calculate the average amount reimbursed for each procedure code (e.g., CPT or HCPCS) by the top five commercial payers for a specified base period. Data from Medicare, Workers' Compensation, and other noncommercial payers and codes not reimbursed by Medicaid are excluded.

(Payer 1 + Payer 2 + Payer 3 + Payer 4 + Payer 5) / (5) = Average Commercial Reimbursement

To compute the reimbursement ceiling, multiply the average reimbursement rate as determined by the number of claims recorded in Medicaid Management Information System (MMIS) for each procedure code that was rendered to Medicaid members by eligible physicians during the base period. Add the product for all procedure codes. This total represents the total reimbursement ceiling.

(Average Commercial Reimbursement) X (Medicaid Count) = Total Reimbursement Ceiling for each Procedure Code

Sum of Total Reimbursement Ceiling for each Procedure Code = Total Reimbursement Ceiling

To determine the Medicare equivalent to the reimbursement ceiling, for each of the billing codes used to determine the reimbursement ceiling, multiply the Medicare rate by the number of claims recorded in MMIS for each procedure code that was rendered to Medicaid members during the base period. Add the product for all procedure codes. This sum represents the total Medicare reimbursement that would have been received. Divide the reimbursement ceiling (commercial payment) by Medicare reimbursement. This ratio expresses the ACR as a percentage of Medicare.

(Medicare Rate) X (Medicaid Count) = Total Medicare Reimbursement for each Procedure Code

Sum of Total Medicare Reimbursement for each Procedure Code = Total Medicare Reimbursement

(Total Reimbursement Ceiling) / (Total Medicare Reimbursement) = Medicare equivalent of the ACR

This single ratio is applied to the Medicare rates for reimbursable Medicaid practitioner services to determine the total allowable Medicaid payment, including both the regular base payment and supplemental payment.

(Medicare equivalent of the ACR) X (Medicare rate per CPT Code for all applicable CPT Codes) = Total Allowable Medicaid Payment

Total Allowable Medicaid Payment – Medicaid Base Payment = Maximum Supplemental Payment

The Medicare equivalent of the ACR demonstration shall be updated every three years. Only the professional component of radiology services and clinical laboratory services is included in the ACR calculation. Claims with a technical component are excluded from the demonstration.
