R225 – Sequestrectomy
OHIP Radiology Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Sequestrectomy is an operative procedure performed under the 'Incision and Drainage' sub-category for the shoulder, arm, and chest within the Musculoskeletal System surgical section. It involves the surgical removal of a piece of dead bone (sequestrum) that has become separated from healthy bone tissue. The '#' prefix indicates that when this service is performed in a hospital or an Integrated Community Health Services Centre (ICHSC), the cost of premises, equipment, supplies, and personnel is covered by the facility's budget and not billed separately. See for details.
When to Use
- Use R225 when performing the definitive surgical removal of a confirmed sequestrum in the shoulder, arm, or chest region.
- Select R225 over R222 (Incision and Drainage) when the primary clinical objective is the excision of dead bone rather than simple drainage of an abscess or soft tissue collection.
Common Pitfalls
- Billing R225 in conjunction with other musculoskeletal procedures on the same site may trigger a 'multiple procedure' reduction or rejection if the documentation does not clearly support distinct operative approaches.
- Failure to document the specific removal of a sequestrum can lead to audits reclassifying the service to a lower-valued incision or debridement code.
Billing Tips
- Ensure the operative report explicitly describes the identification and removal of the sequestrum to justify the R225 fee over simpler debridement codes.
- Since R225 is a '#' code, do not bill for facility-related overhead when performed in a hospital or ICHSC setting, as these costs are covered by the global budget.
