Summary
Blue Cross Blue Shield of Mississippi has established comprehensive anesthesia billing requirements, mandating that general anesthesia services must use CPT codes 00100-01999 only, not surgical codes with anesthesia modifiers. The policy details specific claim filing procedures for different practitioner types and requires proper HCPCS Level II modifiers for all anesthesia services.
Action Required
Immediately: Billing team must verify all anesthesia claims use only CPT codes 00100-01999 for general anesthesia services, never surgical codes with anesthesia modifiers. Update billing system to require appropriate HCPCS Level II modifiers (AA, AD, QK, QY for anesthesiologists; QX, QZ for CRNAs). Configure claims filing to use CMS-1500 forms for independent practitioners and appropriate forms based on hospital participation in BCBSMS APC program. Incorrect claims will be rejected or returned and must be refiled.
