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.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

58110 billing questions
When should 58110 be reported instead of 58100?
Report 58110 when endometrial sampling is performed in conjunction with a colposcopy. Use 58100 for endometrial sampling performed without colposcopy.
Does a cervical biopsy or endocervical curettage support 58110?
No. The add-on represents sampling of the uterine lining; cervical biopsy and endocervical curettage sample different sites.
Which primary procedure is reported with 58110?
Report it with the appropriate primary colposcopy procedure. The add-on is paid within that primary procedure's global period.
What documentation supports 58110?
Document the colposcopy and the separate endometrial sampling, including the indication, sampling method, and uterine lining specimen.
Can 58110 be reported for a stand-alone endometrial biopsy?
No. This is an add-on for endometrial sampling performed with colposcopy; 58100 is the relevant code for sampling without colposcopy.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
