About OB/GYN billing
OB/GYN delivery codes are 'global' — they include prenatal care, delivery, and postpartum care. Separate billing for included services is improper unbundling.
Request the itemized bill. Prenatal visits billed separately from the global delivery code (59400/59510) are improper.
How to dispute a CPT 58300 overcharge
- Request the itemized bill. You are entitled to a detailed line-by-line bill showing every CPT code billed. Ask in writing.
- Compare to Medicare allowable. If the charge exceeds 150% of Medicare ($162), you have grounds to dispute.
- 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.
- Send a formal dispute letter. Cite the specific discrepancy between the documentation and the code. Reference Medicare rates and NCCI edits where applicable.
- Follow up in writing. Give the provider 30 days to respond. If they don't, escalate to the state attorney general and insurance commissioner.
