5 Key Takeaways
-
1
Category III CPT codes, or T codes, are temporary codes for emerging technologies, services, procedures, and service paradigms.
-
2
T codes support specific data collection on utilization and outcomes, unlike unlisted codes.
-
3
A Category III code may become a Category I code, be revised or extended, or be archived, generally 5 years after publication or extension.
-
4
T codes lack nationally assigned relative value units, so reimbursement is payer-driven and can vary significantly.
-
5
Practices should regularly review current CPT guidance and payer policies because codes, descriptors, instructions, effective dates, coverage, and reimbursement can change.
