Understanding Coronary artery angio s&i costs
Coronary artery angio s&i (CPT code 93454) is a medical procedure . Medicare reimburses this procedure at $882 in a facility setting and $99 in a non-facility (office) setting. Hospital chargemaster prices for this procedure are typically 2x to 5x above Medicare rates.
Ambulatory Surgery Centers (ASCs) offer a lower-cost alternative at $1,656 — a potential savings of $-774 compared to the hospital outpatient rate. The actual amount you owe depends on your insurance plan, deductible status, and whether the provider is in-network.

Common billing errors for Coronary artery angio s&i
Billing errors for Coronary artery angio s&i include: upcoding to a higher-complexity code, unbundling components that should be included in a single charge, duplicate charges for the same service, charging facility fees when the procedure was performed in an office setting, and billing for services not actually rendered. If you see CPT 93454 on your bill alongside related codes, verify they are not already bundled per NCCI (National Correct Coding Initiative) edits.
What to check on your bill
Request an itemized bill and verify: (1) the CPT/HCPCS code matches the procedure actually performed, (2) the date of service is correct, (3) no duplicate line items exist for the same procedure, (4) modifier codes are appropriate (e.g., bilateral, reduced services), (5) the charge is not dramatically higher than the Medicare rate of $882, and (6) any ancillary charges (anesthesia, pathology, supplies) are reasonable and not already bundled into the primary procedure code.
