Home Health Claims Processing: Notice of Admission (NOA) Compliance

Effective November 1, 2026, Medicare home health claims submitted without a valid NOA, or outside of required timeframes, will be processed in accordance with CMS guidelines and may be subject to denial, reduction or adjustment.

As a reminder, Medicare home health claims are processed in accordance with CMS guidelines outlined in MLN Matters Article MM12256, which established the notice of admission (NOA) submission requirements.

Under these requirements:

• A one-time NOA submission is required to establish the home health period of care and must be on file prior to billing claims.
• The NOA must be submitted within five (5) calendar days of the start of care date.
• Claims are processed for payment only after a valid NOA is received and must align with the established episode of care.
• Failure to submit a timely NOA may result in payment reductions or claim impact in accordance with CMS policy.
