Aetna 2024 Coding Updates
Key changes affecting independently credentialed IBCLCs regarding E/M 99202–99215. As of September 2024, Aetna updated its reimbursement policy to remove certain codes.
Standard E/M codes 99202–99215 and the prolonged services code 99417 are no longer payable for independently credentialed IBCLCs. Providers must shift documentation and billing to counseling codes and S9443 only when services are performed in the office setting to avoid formal denials and ensure claim accuracy.
What This Means for Your Practice
REIMBURSEMENT IMPACT
The shift away from E/M 99202–99215 codes represents a significant change in how Aetna values lactation services from independently credentialed IBCLCs. For many practices, this means a new reliance on counseling codes 99404-99401 for reimbursement. Success in 2024 requires a deep dive into payer-specific rules and a strategic adjustment to your documentation and coding workflow to ensure full compensation for the expert care you provide. Visit lengths that were previously billable are not longer. Reimbursement is decreased as well.
