What to do
Action · 8 steps
01REQUIREMENTS:
- By June 3, 2024 (already effective): Billing and clinical staff must update prior authorization and claims submission processes for CPT 19318 (breast reduction) to implement the revised medical necessity criteria.
02- Update clinical documentation requirements to ensure providers document that adolescent patients have maintained stable cup size for at least 6 months prior to surgery.
03Add this as a required field on pre-authorization forms.
04- For all reduction mammoplasty claims, ensure diagnosis code N65.1 (Disproportion of reconstructed breast) is submitted as PRIMARY DIAGNOSIS when applicable (previously may have been coded as clinical symptom).
05Update billing software coding rules and encoder logic to reflect this change.
06- Billing team must verify that all pending and newly submitted claims for reduction mammoplasty include documentation of the "reasonable likelihood that symptoms are primarily due to size or weight of breasts" as required by updated criteria.
07- If claims have been recently denied or are under review with previous coding for N65.1, consider re-submission with corrected diagnosis code hierarchy.
08- Failure to implement the adolescent cup size stability requirement will result in pre-authorization denials; failure to use N65.1 as primary diagnosis may cause claim rejections or payment delays.
