What 28070 covers

The surgeon removes abnormal synovial tissue from a tarsometatarsal joint, where the metatarsal bases meet the midfoot bones. This may be performed for persistent synovitis with inflamed or proliferative joint lining, including inflammatory disease affecting the midfoot. A foot and ankle or orthopedic surgeon typically performs the operation in an operating room.

Report 28070 when the operative work removes synovium from a tarsometatarsal joint; a limited diagnostic tissue sample is not the same service. The operative note should identify the joint and document the synovial tissue removed. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When other procedures subject to multiple-procedure reduction are 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 for an assistant at surgery, co-surgeons, or team surgery for this code.

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.

How is 28070 distinguished from 28072?

28070 is for synovectomy of a tarsometatarsal joint. 28072 applies to a metatarsophalangeal joint, so use the joint documented in the operative report.

Can 28070 be reported for a synovial biopsy?

Use 28070 when the surgeon removes synovial tissue as a synovectomy. A procedure limited to obtaining tissue for diagnosis is a biopsy service instead.

Should modifier 50 be appended for bilateral procedures?

No. CMS identifies bilateral adjustment as inappropriate for this code's descriptor or anatomy.

What postoperative care is included?

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

How are other procedures in the same session paid?

Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and the other procedures are paid at 50%. Medicare does not pay an assistant at surgery, co-surgeons, or team surgery for 28070.

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.
