    Definition

    Category III CPT codes (T codes) allow data collection on emerging procedures and devices. They sunset after five years unless converted to Category I, but can be extended.

    What this means in practice

    Category III codes do not guarantee payment but enable claims tracking and serve as evidence for future Category I applications and coverage decisions.
