Mean allowed charge estimate $103 per case for anesthesiologist involvement
16,268 (total number of procedures in our sample) multiplied by 20 (our cohort was derived from 5% sample of Medicare beneficiaries) divided by 0.28 (SEER data represents only 28% of US population)
1,162,000 (total number of procedures in US Medicare) × $575.20 (average cost of procedure without anesthesiologist involvement)
1,162,000 (total number of procedures in US Medicare) × $575.20 (average cost of procedure without anesthesiologist involvement) × 0.828 (percentage without anesthesiologist involvement) + 1,162,000 (total number of procedures in US Medicare) × $678.20 (average cost of procedure with anesthesiologist involvement) × 0.172 (percentage with anesthesiologist involvement)
1,162,000 (total number of procedures in US Medicare) × $678.20 (average cost of procedure with anesthesiologist involvement)
