Summary
Effective August 1, 2026, Anthem Blue Cross and Blue Shield (Georgia) will deny inpatient facility claims that list an unacceptable primary diagnosis code as defined by CMS guidelines. Claims with incorrect primary diagnosis sequencing will not be reimbursed and must be resubmitted with corrected coding. Billing teams must review all inpatient PDX selections before submission to ensure they reflect the primary reason for admission, not secondary diagnoses.
Action Required
By August 1, 2026: Billing team must implement a pre-submission review process for all inpatient facility claims to verify primary diagnosis (PDX) coding is acceptable per CMS guidelines and reflects the true primary reason for admission. Review ICD-10-CM coding guidelines to identify unacceptable PDX codes that must be sequenced as secondary diagnoses only. Update billing workflows to flag claims with potentially inappropriate primary diagnosis codes before submission. Providers must ensure accurate PDX selection on all inpatient encounter documentation. Train all coding and billing staff on CMS PDX guidelines. Establish a process to track and resubmit denied claims with corrected PDX coding via Availity (https://Availity.com → Help & Training → search 'correct a claim'). Failure to correct inappropriate PDX coding will result in claim denials and lost reimbursement.
