Summary
Anthem Blue Cross and Blue Shield Medicare Advantage plans in Ohio will now reject claims exceeding 449 service lines (excluding the total charge line) as a single claim submission. Billing teams must implement immediate changes to combine service lines, split claims by date of service, or submit inpatient claims as interim bills to comply with this CMS alignment requirement.
Action Required
Immediately: Billing team must implement the following changes to all Medicare Advantage claim submissions for Ohio Anthem members: (1) Review current billing practices to identify claims with more than 449 service lines; (2) Update billing software to enforce the 449 service line limit per encounter; (3) Implement one or more of the following strategies for claims exceeding the limit: combine service lines where clinically appropriate, split outpatient claims by date of service, or submit inpatient claims as interim bills; (4) Train billing staff on the new 449 service line threshold and approved reduction strategies; (5) Contact Anthem provider representative if questions arise during implementation. Failure to comply will result in claim denials and rejections from Anthem Blue Cross and Blue Shield for Ohio Medicare Advantage members.
