Private insurance typically pays 1.2–1.8x Medicare rates ($532–$797). Hospital chargemaster prices for CPT 93306 often range from $700 to $2500 — a markup of 1.6x to 5.6x over Medicare.

About Cardiology billing

Cardiology procedures are frequently overcharged through facility-fee stacking — where the same test at a hospital-owned imaging center costs 3–5x what it does at an independent cardiology practice.

How to dispute a CPT 93306 overcharge

  1. Request the itemized bill. You are entitled to a detailed line-by-line bill showing every CPT code billed. Ask in writing.
  2. Compare to Medicare allowable. If the charge exceeds 150% of Medicare ($665), you have grounds to dispute.
  3. Request documentation. For E&M codes, ask for the visit note. For procedures, ask for the operative report. The documentation must justify the code billed.
  4. Send a formal dispute letter. Cite the specific discrepancy between the documentation and the code. Reference Medicare rates and NCCI edits where applicable.
  5. Follow up in writing. Give the provider 30 days to respond. If they don't, escalate to the state attorney general and insurance commissioner.
