Foot surgery

About 28052: Open metatarsophalangeal joint lining biopsy

Report this service when a surgeon opens a metatarsophalangeal joint to obtain synovial tissue for diagnostic evaluation.

A foot and ankle surgeon, orthopedic surgeon, or podiatric surgeon opens a metatarsophalangeal joint and takes a sample of its synovial lining. The tissue may be sent for evaluation when the cause of joint inflammation or another abnormal process remains uncertain. This is an open joint procedure, not simply a needle sample or inspection of the joint. The code is specific to the metatarsophalangeal joint; the operative report should identify the joint and document the tissue sampled.

Report the service for the joint actually biopsied, supported by the operative note and specimen documentation. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. For bilateral reporting with modifier 50, CMS pays at 150%. Medicare does not pay an assistant at surgery for this code. Co-surgeon payment requires supporting documentation, and team surgery is not permitted.

For 28052 in Vallejo, the physician’s office rate is $458.53 and the facility-setting rate is $275.83: a difference of $182.70.

28052 billing questions

How is this code distinguished from 28050?

This code is for biopsy of a metatarsophalangeal joint lining. Code 28050 is for a different foot-joint site, so the operative report must identify the joint entered.

How is this code distinguished from 28054?

Use this code for a metatarsophalangeal joint biopsy and 28054 for an interphalangeal toe-joint biopsy. The documented joint site determines the choice.

Can the biopsy be reported separately from the joint procedure?

The joint exposure and synovial sampling are represented by this service; do not separately report another biopsy procedure for the same tissue collection.

What documentation supports reporting this code?

Document the metatarsophalangeal joint entered, the open approach, the synovial tissue obtained, and the reason for diagnostic sampling.

How does Medicare handle bilateral reporting and other procedures in the session?

CMS pays bilateral reporting with modifier 50 at 150%. For multiple procedures in one session, the highest-valued procedure is paid in full and others are subject to the standard 50% reduction.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
