The National Defense Authorization Act of 2017, signed on December 12, included a provision adding PTAs (and OTAs) as authorized providers under TRICARE. However, this change is not yet effective. The change to regulation will be implemented through the notice and comment rulemaking process. The proposed rule has not yet been released; it is expected in the fall of 2018 or spring of 2019. A 60-day comment period will follow the release of the proposed rule, after which the Department of Defense will review the comments and draft and publish the final rule. Until the rule is finalized and published, TRICARE does not consider a PTA as an authorized provider, and the rule will not be retroactive. APTA will keep members informed of the timeline for this changeover to the TRICARE system.
