Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 58555 covers

A gynecologist passes a hysteroscope through the cervix to inspect the endometrial cavity, for example when evaluating abnormal uterine bleeding or a suspected intracavitary abnormality. The procedure may be performed in an office or outpatient surgical setting. This code represents diagnostic visualization, not hysteroscopic sampling or treatment of a finding.

Report it when diagnostic inspection is the hysteroscopic service performed; document the indication, findings, and whether any operative work was done. Because it is a separate procedure, diagnostic inspection is generally not separately reported when it is part of a hysteroscopic biopsy or treatment. The 0-day global period includes same-day preoperative and postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are reduced by 50%. Bilateral adjustment is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons are permitted, while team surgery is not permitted.
