Documentation requirements
What must appear in the operative or office note to support the claim.
Source · Editorial brief grounded in 5 cited references ↓
- Operative note must specify the level of humeral resection with measured bone length remaining post-procedure
- Indications for re-amputation documented: non-healing wound, infection, prosthetic incompatibility, or other specific clinical rationale
- Description of soft-tissue management — primary closure, flap technique, or planned open wound — with suture layers identified
- Prior amputation history including original procedure date, level, and reason the existing stump is inadequate
- If modifier 22 is appended, document operative time and the specific factors that made the procedure significantly more complex than typical

What this code covers
Source · Editorial summary grounded in 5 cited references ↓
CPT 24930 covers surgical re-amputation through the humerus when an existing above-elbow amputation stump requires revision — typically because of non-healing wounds, infection, inadequate bone length, or soft-tissue geometry that prevents prosthetic fitting. The surgeon resects additional humeral length and reshapes or closes the soft-tissue envelope to create a functional, prosthesis-ready residual limb. This is a distinct revisional procedure, not routine stump care, and carries a 90-day global period.
Do not confuse 24930 with adjacent codes in the amputation family. 24925 is scar revision or secondary closure of a prior amputation stump — no bone resection. 24931 is re-amputation with implant placement. 24935 is stump elongation, the opposite intent. If the re-amputation is complicated by significant additional work — extensive debridement, flap reconstruction, or unusually difficult anatomy — modifier 22 applies, but requires supporting documentation of the increased operative time and complexity.
The 90-day global includes the day-before preoperative visit, the procedure day, and all routine post-op stump management through day 90. Prosthetic fitting consultations and unrelated E/M visits in that window need modifier 24. A staged or planned second procedure on the same stump within the global requires modifier 58; an unplanned return to the OR for a related complication uses modifier 78.

Common denial reasons
The recurring reasons claims for CPT 24930 get rejected.
Source · Editorial brief grounded in CMS NCCI edits, AAOS coding appeals, and cited references ↓
- Missing or vague clinical indication — notes that say 'stump revision' without specifying why the existing amputation is inadequate
- Upcoded as 24931 (with implant) without documentation of implant placement, or downcoded to 24925 when bone resection was actually performed
- Global period conflict — routine post-op stump care billed separately within the 90-day window without modifier 24 or 79
- Modifier 22 appended without documentation of increased operative time or specific complexity factors to support the upward adjustment
- ICD-10 diagnosis mismatch — using a primary amputation diagnosis code rather than a complication or late-effect code appropriate for a revision procedure

Mira AI Scribe
Mira's AI scribe captures the specific clinical indication for re-amputation (wound breakdown, infection, bone prominence, prosthetic incompatibility), the measured humeral length remaining after resection, the soft-tissue closure technique, and operative time. That documentation prevents the two most common audit flags: a vague indication that reads like routine stump care rather than a distinct surgical re-amputation, and an unsupported modifier 22 claim lacking operative complexity detail.
