By April 15, 2003: (1) Billing team must remove prior authorization requirements from billing system for HCPCS codes L3001-L3090 and L3201-L3223 ONLY when paired with approved diagnosis codes (343.0-343.9, 707.0-707.9, 711.0-712.9, 715.0-722.9, 724.0-728.9, 730.0-737.9, 754.2-754.79, 755.0-755.39, 755.6-755.69, 756.1-756.19, 756.8-756.89, 892.0-897.7). (2) Update NJMMIS billing rules to enforce automatic utilization limits: 4 units/12 months for L3001-L3003, L3010, L3020, L3030, L3040, L3050, L3060, L3070, L3080, L3090; 2 units/12 months for L3201-L3207, L3215-L3217, L3219, L3221-L3222; 4 units/12 months for L3218, L3223, X4890-X4892. (3) Providers must validate diagnosis codes before submission—claims with inappropriate diagnosis codes will be denied with Error Code 251 and cannot be appealed through prior authorization. (4) Prepare for post-payment medical record audits. (5) Inform providers that incorrect diagnosis code reporting may trigger payment recoupment and audit actions. Failure to comply will result in automatic claim denials and potential financial penalties.
