T645 – T645
OHIP Other Code · Schedule of Benefits
When to Use
- Use T645 for the removal of a simple, superficial skin tag or small lesion that does not require formal excision or suturing.
- Apply this code for the removal of a single pedunculated lesion where the procedure is limited to a simple snip or cautery.
Common Pitfalls
- Billing T645 in addition to a minor surgery code like Z001 or Z002 for the same lesion is considered double-billing and will be rejected.
- Using T645 for lesions requiring excision with closure (e.g., Z003 or Z004) is an audit risk as it misrepresents the complexity of the procedure performed.
Billing Tips
- If removing multiple lesions, ensure you are billing the appropriate multiple lesion codes rather than attempting to stack T645 units, as the Schedule of Benefits specifies the allowed billing structure for multiple procedures.
