Summary
New Jersey Medicaid and NJ KidCare fee-for-service programs established temporary billing codes (W9346 and W9347) for Rituxan (Rituximab) reimbursement effective immediately. These Level III HCPCS codes are valid until a permanent 'J' code is designated by CPT. E/M services are only reimbursable when separately identifiable and documented.
Action Required
Immediately: Billing team must update system to recognize temporary HCPCS codes W9346 (Rituxan 100 mg vial, $397.50) and W9347 (Rituxan 500 mg vial, $1,987.50) for New Jersey Medicaid and NJ KidCare fee-for-service claims. Providers must ensure separate E/M services are clearly documented in patient records if billing concurrent evaluation and management codes—claims with undocumented E/M will be denied. Monitor for CPT designation of permanent 'J' code and transition billing codes when announced. Retain this newsletter in files for reference.
