What 66830 covers

An ophthalmic surgeon uses this code for surgical removal of a discrete lesion involving the natural lens, such as a lens cyst or tumor. The operative target is the lesion itself, rather than a secondary cataract membrane or lens material removed as part of cataract surgery. The procedure is typically performed in a surgical setting, with the surgeon documenting the lesion and the removal performed.

Select the code based on the operative report’s description of a lens lesion and its removal. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. For bilateral surgery reported with modifier 50, CMS pays 150%. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Assistant-at-surgery services are not paid; co-surgeons and team surgery are not permitted.

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.

66830 billing questions

How is this code different from lens-material removal codes?

Use this code when the surgeon removes a discrete lesion involving the natural lens. Codes for lens-material removal describe procedures directed at lens material rather than a cyst or tumor.

Does the global period include postoperative care?

Yes. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.

How is bilateral surgery reported?

Report bilateral surgery with modifier 50. CMS pays 150% for the bilateral procedure.

Can an assistant surgeon be paid for this procedure?

CMS does not pay assistant-at-surgery services for this code. Co-surgeons and team surgery are also not permitted.

What documentation supports reporting this code?

The operative report should identify the discrete lens lesion, such as a cyst or tumor, and describe its surgical removal. Documentation should distinguish that target from a secondary cataract membrane or lens material.
