For SNF billing for PEN, a SNF includes the charges for PEN items it supplies beneficiaries under Part A on its Part A bill. The services of SNF personnel who administer the PEN therapy are considered routine and are included in the basic Part A payment for a covered stay. SNF personnel costs to administer PEN therapy are not covered under the Part B prosthetic device benefit.

If TPN supplies, equipment and nutrients qualify as a prosthetic device and the stay is not covered by Part A, they are covered by Part B. Part B coverage applies regardless of whether the TPN items were furnished by the SNF or an outside supplier. The Part B TPN bill must be sent to the DME Medicare Administrative Contractor regardless of whether supplied by the SNF or an outside supplier.

Enteral nutrients provided during a stay that is covered by Part A are classified as food and included in the routine Part A payment sent to the SNF. (See the Medicare Provider Reimbursement Manual, §2203.1E.) Parenteral nutrient solutions provided during a covered Part A SNF stay are classified as intravenous drugs. The SNF must bill these services as ancillary charges. (
