Anthem Medicare Advantage reimbursement policy for professional anesthesia services aligns its reimbursement formula and time increments with CMS guidelines and requires use of industry-standard CPT/HCPCS/revenue codes and appropriate modifiers. Policies apply to participating providers and facilities; non‑contracting providers who accept Medicare assignment are reimbursed according to original Medicare rates. Key topics covered include time reporting in minutes (with 15‑minute time units), proper modifier usage and reimbursement impacts (AA, AD, QK, QX, QY, QZ, 23, 47), multiple‑procedure reimbursement rules (highest base unit + total time), obstetrical neuraxial/epidural limits (reimbursable up to 300 minutes with documentation required for excess), separately reimbursable ancillary procedures (e.g., Swan‑Ganz catheter, CVP lines, intra‑arterial lines, emergency intubation, critical care visits, transesophageal echocardiography), and nonreimbursable items (e.g., patient status modifiers for complexity, anesthesia consultations on the day of surgery when part of preop assessment, services for noncovered procedures, anesthesia by the operating provider except for delivering physician epidurals, and local anesthesia incidental to the procedure).
