What 46924 covers

This code describes extensive destruction of lesions on the anus, including lesions such as condylomata, papillomas, or molluscum contagiosum. A colorectal or general surgeon may perform the treatment in an office procedure room or an outpatient setting. The lesions are destroyed rather than removed as tissue specimens; the code is selected for extensive treatment, not simply because more than one lesion is present.

Document the lesion sites and extent, the destructive method, and why the treatment is extensive rather than simple. Related postoperative visits during the 10-day global period are included. When multiple procedures are performed in the same session, Medicare pays the highest-valued procedure in full and applies the standard reduction to the others. Modifier 50 is inappropriate for this code. Medicare does not pay for an assistant at surgery, and co-surgeon and team-surgery billing 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.

46924 billing questions

How is 46924 distinguished from 46900?

46924 is for extensive destruction; 46900 is for simple destruction. Document the extent of treatment and the method used rather than relying only on the number of lesions.

Is 46924 used for excision of anal lesions?

No. It represents destruction of lesions. Use 46922 when lesions are excised and removed as tissue.

Are postoperative visits separately reported?

Related postoperative visits during the 10-day global period are included in 46924.

Can modifier 50 be reported?

No. Bilateral adjustment is inappropriate for this code and modifier 50 should not be used.

How does Medicare handle other procedures performed in the same session?

The highest-valued procedure is paid in full, and other procedures subject to the multiple-procedure rule are reduced under the standard Medicare adjustment. Medicare does not pay for an assistant at surgery; 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.
