Key legal question
Whether the three-year time limit for occupational therapy in KSME No. 404.11 has a legal basis
Extracted holding
The circular’s three-year time limit lacks a sufficient legal basis; entitlement cannot be denied solely for that reason.
Extracted reasoning
Administrative instructions may concretize the law but cannot add restrictive substantive requirements not found in the statute or ordinance. The relevant criteria remain medical indication, simplicity, appropriateness, and reasonable cost-effectiveness under Art. 2(3) GgV.
