What 58110 covers
This add-on represents a sample of the uterine lining obtained while the clinician performs a colposcopy. An OB-GYN or other qualified clinician may use an office endometrial sampler to investigate a uterine concern, such as abnormal bleeding, during a visit that also evaluates an abnormal cervical screening result. The endometrial specimen is distinct from tissue taken from the cervix or endocervical canal during colposcopy.
Report 58110 only with the primary colposcopy procedure; use 58100 for endometrial sampling performed without colposcopy. The record should identify the colposcopy and separately document endometrial sampling, its indication, method, and specimen. Cervical biopsy or endocervical curettage alone does not represent sampling of the uterine lining. CMS pays this add-on within the primary procedure's global period, so payment is associated with that primary service's global period.
