G490 – Saralasin test
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
The Saralasin test is a diagnostic procedure listed under the Endocrinology and Metabolism section of Diagnostic and Therapeutic Procedures. It is used to assess certain endocrine functions. As with all insured services, it includes all common elements as described in the Schedule of Benefits (, ).
When to Use
- Use G490 specifically when performing a Saralasin infusion test for the investigation of renin-dependent hypertension.
- Select G490 when documenting the diagnostic assessment of endocrine-mediated blood pressure regulation in a clinical setting.
Common Pitfalls
- Billing G490 as a standard office visit (A007) is a common error; G490 is a procedure code and should not be billed concurrently with an assessment code unless a separate, distinct clinical issue is addressed.
- Failure to document the specific diagnostic indication for the Saralasin test often leads to audit scrutiny regarding the medical necessity of the procedure.
Billing Tips
- Since G490 is a diagnostic procedure, ensure it is billed with the appropriate diagnostic code for hypertension or endocrine dysfunction to avoid rejection.
- You may append eligible Special Visit Premiums (Tables I-IX) to G490 if the procedure is performed on an urgent or emergency basis outside of standard office hours.
