G037 – Sperm antibodies – titre
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
The G037 service is for the measurement of the titre of sperm antibodies. As with all insured services, this procedure includes the common elements outlined in the General Preamble on pages to , such as obtaining history, maintaining records, and conferring with other professionals.
When to Use
- Use G037 when a specific quantitative titre measurement is required for sperm antibodies following a positive screening result from G036.
- Use this code for patients undergoing fertility investigations where immunological infertility is suspected as a cause for failed fertilization.
Common Pitfalls
- Billing G037 without a preceding G036 or clinical justification for the titre measurement often triggers manual review or rejection.
- Submitting G037 for routine semen analysis or general fertility screening without specific clinical indication for antibody testing is a common audit trigger.
Billing Tips
- Ensure the laboratory requisition clearly specifies the need for a titre measurement to support the medical necessity of G037 over the screening code G036.
