Z149 – Single lesion - Other areas - General anaesthetic
OHIP Psychiatric Code — INTEGUMENTARY SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Surgical procedure listed in the Schedule of Benefits, typically under the Musculoskeletal System section. The specific anatomical location and procedural details for `Z149` are not specified in the provided context. The service is subject to general rules for surgical procedures, including specific rules for admission assessments when a 'Z' prefix code is used as detailed in . Suffix 'A' is used for the surgeon, 'B' for the surgical assistant, and 'C' for the anaesthetist.
When to Use
- Use Z149 for the excision or treatment of a single musculoskeletal lesion when the procedure is performed under general anaesthesia.
- Select Z149 when the specific anatomical site does not have a more specific procedural code defined in the Schedule of Benefits, serving as a catch-all for 'other areas' under general anaesthetic.
Common Pitfalls
- Billing Z149 for procedures performed under local anaesthesia; this code specifically requires general anaesthesia to be eligible for the fee.
- Failing to account for the 'Z' prefix rules regarding admission assessments; per GP23, an admission assessment by the surgical specialist is considered a re-assessment if they previously assessed the patient for the same condition.
Billing Tips
- Ensure the operative report explicitly documents the use of general anaesthesia to support the Z149 claim in the event of an audit.
- If the procedure is non-elective and occurs after hours, ensure you append the appropriate E409 or E410 premium to the Z149 base fee to maximize reimbursement.
