What 25375 covers

This operation corrects a deformity involving both forearm bones by cutting and removing a segment of bone so the surgeon can revise their alignment. An orthopedic or hand surgeon typically performs it in an operating room. The operative report should establish that the correction involved both the radius and ulna and included segmental resection, rather than a procedure on one bone or a shortening or lengthening osteotomy.

Report the code when the documented work matches that two-bone procedure; include the bones treated, operative levels, resection, and corrective work in the record. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is 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.

How to choose

25365Forearm osteotomy
Both codes involve the radius and ulna, but this code is distinguished by segmental resection. Choose 25365 when the documented procedure does not include that resection.
25370Forearm osteotomy
25370 is for segmental-resection osteotomy of one forearm bone; this code requires treatment of both the radius and ulna.
25392Forearm osteotomy
25392 describes shortening both forearm bones. This code is selected for the documented segmental-resection correction rather than a shortening procedure.
25393Forearm lengthening
25393 describes lengthening both forearm bones. This code is for the segmental-resection corrective procedure, not a lengthening procedure.

25375 billing questions

How does this differ from 25365?

This code is for correction involving both the radius and ulna with segmental resection. Use 25365 when the documented two-bone osteotomy does not include that resection.

Can this code be used when only one forearm bone is treated?

No. The procedure must involve both the radius and ulna. For segmental-resection osteotomy of one bone, compare 25370.

What documentation supports reporting this code?

Document the deformity addressed, both bones treated, the osteotomy and segmental resection performed, and the corrective work. The operative details should distinguish it from single-bone and shortening or lengthening procedures.

How is bilateral treatment reported?

CMS identifies this as a bilateral procedure. Modifier 50 is paid at 150% when the procedure is performed bilaterally.

Are assistant or co-surgeon services payable?

An assistant at surgery may be paid. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.

What postoperative care is included?

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