What 46050 covers

This service drains a superficial collection in the perianal tissues through an incision, allowing the abscess contents to escape. It is typically performed by a surgeon or other qualified clinician in an office or outpatient setting. The key distinction is the abscess location and depth: a collection confined to superficial perianal tissue differs from a deeper ischiorectal or perirectal abscess, or one drained through a transanal approach under anesthesia.

Report the code when the operative or procedure note identifies a superficial perianal abscess and documents incision and drainage. Related postoperative visits are included in the 10-day global period. If another procedure subject to the standard multiple procedure reduction is performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service; 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.

46050 billing questions

How does this differ from drainage of an ischiorectal abscess?

Use 46050 for a superficial perianal collection. A deeper ischiorectal or perirectal abscess points to a different drainage code, such as 46040 or 46060, depending on the documented site and procedure.

When is 46045 a better fit?

46045 describes transanal drainage of an abscess under anesthesia. Code 46050 is for incision and drainage of a superficial perianal abscess, not the transanal approach.

Are postoperative visits included?

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

Can modifier 50 be used for bilateral abscesses?

No. The CMS bilateral adjustment does not apply to 46050, and modifier 50 is inappropriate for this code.

How are other procedures in the same session paid?

Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other affected procedures are paid at 50%. Medicare does not pay an assistant at surgery for 46050, and 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.
