1.0 DESCRIPTION
Category
III codes are a set of temporary codes for emerging technology,
services, and procedures. These codes are used to track new and
emerging technology to determine applicability to clinical practice.
When a Category III code receives a Category I code from the American
Medical Association (AMA) it does not automatically become a benefit
under TRICARE. However, the codes that may have moved from unproven
to proven must be forwarded to the Office of Medical Benefits and Reimbursement Section (MB&RS)
for coverage determination/policy clarification.
2.0 POLICY
2.1 Category III codes are to be used instead of
unlisted codes to allow the collection of specific data. TRICARE
has not opted to track Category III codes at this time.
2.2 Category III codes are excluded from coverage
since clinical safety and efficacy or applicability to clinical
practice has not been established.
3.0 EXCEPTIONS
3.1 U.S. Food and Drug Administration (FDA) Investigational
Device Exemption (IDE) (Category B) clinical trial. See
Chapter 8, Section 5.1.
