Z772 – Thymus transplant
OHIP Psychiatric Code — ENDOCRINE SURGICAL PROCEDURES · Schedule of Benefits
Thymus transplant is a surgical procedure for the implantation of a thymus gland. The fee for this service covers the surgical component. Anaesthesia services are billed separately based on a unit system.
When to Use
- Use Z772 specifically for the surgical implantation of a thymus gland.
- Use this code when the procedure is performed as a primary surgical intervention, ensuring the surgical component is distinct from anaesthesia units.
Common Pitfalls
- Failing to include the Injury Severity Score (ISS) in the medical record when attempting to claim the E420 trauma premium, which leads to automatic rejection.
- Attempting to bill for a surgical assistant without prior authorization; you must use M400B and provide a supporting letter from the surgeon to justify the assistance.
- Incorrectly applying age-based premiums by failing to verify the patient's exact age in days or years against the specific thresholds defined in the Schedule of Benefits.
Billing Tips
- When an assistant is required, ensure the claim for M400B includes the basic units equivalent to the anaesthesia units for Z772 and is accompanied by the required justification letter.
- Always verify the patient's age at the time of the procedure to correctly apply the appropriate percentage increase (10% to 30%) as outlined in the age-based premium criteria.
