Key legal question
Whether unused psychotherapy sessions from one period may be carried forward to the next reimbursement period under OPAS Article 3.
Extracted holding
No. The progressive reduction scheme does not permit carrying over sessions that were not used during the relevant period.
Extracted reasoning
The court held that the OPAS regime fixes the reimbursable number of sessions by period and provides for a gradual reduction over several years; allowing carryover would contradict that staged limitation.
