What 65800 covers

Code 65800 describes entry into the eye’s anterior chamber to withdraw aqueous humor. Ophthalmologists may perform it to lower elevated pressure, including in an acute pressure crisis, or to collect aqueous for diagnostic analysis. The procedure may be done in an office or facility setting and is distinct from removing vitreous or performing a more extensive glaucoma operation.

Report the code when the documented service is anterior chamber paracentesis with aqueous removal. Record the treated eye, clinical reason, procedure performed, and whether a specimen was collected. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and the others are subject to the standard multiple procedure reduction. For bilateral services, modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; 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.

65800 billing questions

How is 65800 distinguished from 65810?

65800 is for anterior chamber paracentesis with aqueous removal. Compare the documented work with 65810 when medication injection is also performed or the service otherwise fits that code’s expanded description.

Can 65800 be reported with another eye procedure on the same date?

The code identifies a separate procedure, so report it when the paracentesis is a distinct service rather than an integral part of a more extensive procedure. Apply the multiple procedure reduction when separate procedures are performed in the same session.

What documentation supports 65800?

Document anterior chamber entry and aqueous removal, the eye treated, and the indication, such as elevated pressure or diagnostic sampling. If fluid is collected, note the specimen and its disposition.

How is bilateral 65800 reported?

For procedures on both eyes, report modifier 50; CMS pays the bilateral procedure at 150%.

Can an assistant or co-surgeon be reported for this procedure?

CMS does not pay an assistant at surgery for 65800. Co-surgeons and team surgery are not permitted.

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.
