What 58300 covers
This procedure reports placement of an intrauterine device (IUD) in the uterine cavity for contraception. An obstetrician-gynecologist, family physician, or other qualified clinician commonly performs the insertion in an office or outpatient clinic. The procedure code describes placement, whether the selected device is hormonal or copper-based; the product depends on the device used.
Medicare lists 58300 with physician fee schedule status N, meaning Medicare does not cover the service. Report one unit for one insertion procedure; the code does not count the device's medication dose. J7300 identifies a copper intrauterine contraceptive device, while J7298 identifies a 52 mg levonorgestrel intrauterine system.
