What 28072 covers

This service removes abnormal synovial tissue from a metatarsophalangeal (MTP) joint in the foot. An orthopedic foot-and-ankle surgeon or podiatric surgeon typically performs it in an operating room, opening the joint to address persistent, symptomatic synovial inflammation or proliferation. The operative focus is the joint lining, not a toe tendon sheath or a diagnostic tissue sample alone.

Report the code when the surgeon performs therapeutic synovial tissue removal at an MTP joint. The operative report should identify the joint, describe the synovial findings and removal, and support why treatment went beyond biopsy. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For procedures in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate for this code. Assistant-at-surgery payment is barred, and co-surgeon and team-surgery reporting 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.

28072 billing questions

How does this differ from 28070?

Code 28072 is for synovectomy at a foot metatarsophalangeal joint. Code 28070 is for synovectomy at a tarsal joint.

When would 28052 be more appropriate?

Use the applicable joint-biopsy code when the surgeon opens the joint to obtain a diagnostic sample rather than therapeutically removing abnormal synovial tissue.

Can modifier 50 be used for bilateral MTP synovectomy?

No. CMS identifies bilateral adjustment as inappropriate for this code, so do not use modifier 50 for a bilateral adjustment.

What postoperative care is included in the global period?

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

Can an assistant or co-surgeon be paid for this service?

CMS bars assistant-at-surgery payment for this code and does not permit co-surgeon or team-surgery reporting.

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.
