What 68525 covers

An ophthalmologist, often an oculoplastic surgeon, samples tissue from the lacrimal sac for diagnostic evaluation. The sac is part of the tear-drainage system near the inner corner of the eye. Biopsy may be considered when abnormal tissue or a suspected lesion requires examination; the specimen is submitted for pathologic evaluation. The operative note should identify the sac as the tissue sampled and explain the clinical reason for biopsy.

Report this service for tissue sampling, rather than removal of the sac. Document the operative findings, biopsy site, and specimen obtained. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard multiple procedure reduction. For bilateral procedures, modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons require supporting documentation, and team surgery is not permitted.

68525 billing questions

How is a sac biopsy different from removal of the tear sac?

Report 68525 when tissue is sampled for diagnosis. When the tear sac itself is removed, consider 68520 instead.

Can tear-sac biopsy be reported with a pathology service?

The biopsy reports the surgical tissue sampling. Any separately reported pathology service represents examination of the specimen, not the act of obtaining it.

What documentation supports 68525?

The operative note should identify the lacrimal sac as the sampled tissue, describe the reason for biopsy and the tissue obtained, and document relevant findings.

How does Medicare treat bilateral reporting?

CMS lists the procedure as bilateral; when both sides are treated, modifier 50 is paid at 150%.

What happens when another procedure is performed in the same session?

Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the other procedures are paid at 50%.
