Z704
Z704 – Testis biopsy - single
OHIP Psychiatric Code — MALE GENITAL SURGICAL PROCEDURES · Schedule of Benefits
A surgical procedure involving the removal of a tissue sample from a single testis for pathological examination.
When to Use
- Use Z704 for a diagnostic biopsy of a single testis when the procedure is performed as a standalone surgical intervention.
- Use Z704 when performing a biopsy for infertility workup or suspected malignancy where only one side is sampled.
Common Pitfalls
- Do not bill Z704 if a bilateral biopsy is performed; use Z705 for bilateral testis biopsy instead to avoid claim rejection for duplicate service.
- Avoid billing Z704 in conjunction with more extensive procedures like an orchiectomy (e.g., Z706) on the same side, as the biopsy is considered an inherent part of the more definitive surgical procedure.
- Ensure the diagnosis code supports the medical necessity of the biopsy to prevent audit flags regarding unnecessary surgical tissue sampling.
Billing Tips
- If the procedure is performed in an after-hours setting, ensure you append the appropriate non-elective surgical premium (E409A or E410A) to the Z704 claim to capture the 50% or 75% fee increase.
