CMS plans to apply “Phase 2” ordering and referring denial edits to certifying physicians of Part A home health agency (HHA) services effective July 1, 2014. These edits, which currently apply only to the attending physician of an HHA, will ensure that the physician that certifies the patient’s eligibility to receive services under the Medicare home health benefit has a valid individual National Provider Identifier (NPI) and are of a specialty type eligible to order and refer the HHA items and services on the claim. The edits will deny the claim when this information is missing or invalid.
