CMS Pub. 100-02, ch. 8, § 50.5
Drugs and Biologicals
A3-3133.5, SNF-230.5, Rev. A3-1838 dated 06/01, A3-3133.5.A, SNF-230.5.A, A3-
3133.5.B, SNF-230.5.B, A3-3133.5.C, SNF-230.5.C, A3-3133.5.D, SNF-230.5.D
Drugs and biologicals for use in the facility, which are ordinarily furnished by the facility
for the care and treatment of inpatients, are covered. Such drugs and biologicals are not
limited to those routinely stocked by the skilled nursing facility but include those
obtained for the patient from an outside source, such as a pharmacy in the community.
Drugs and biologicals are included in the SNF PPS except for those Part B drugs
specifically excluded. Since the provision of drugs and biologicals is considered an
essential part of skilled nursing care, a facility must assure their availability to inpatients
in order to be found capable of furnishing the level of care required for participation in
the program. When a facility secures drugs and biologicals from an outside source, their
availability is assured only if the facility assumes financial responsibility for the
necessary drugs and biologicals, i.e., the supplier looks to the facility, not the patient, for
payment.
Payment may not be made for particular uses of drugs that the FDA has expressly
disapproved or that are designated as not covered in the Medicare National Coverage
Determinations Manual, chapter 2.
If the A/B MAC (A) has reason to question whether the FDA has approved a drug or
biological for marketing, it will obtain satisfactory evidence of FDA’s approval.
Acceptable evidence includes a copy of the FDA’s letter to the drug’s manufacturer
approving the new drug application (NDA); or listing of the drug or biological in the
FDA’s “Approved Drug Products” or “FDA Drug and Device Product Approvals”; or a
copy of the manufacturer’s package insert, approved by the FDA as part of the labeling of
the drug, containing its recommended uses and dosage, as well as possible adverse
reactions and recommended precautions in using it. When necessary, the Medicare
regional office may be able to help in obtaining information.
See instruction in the Medicare Benefit Policy Manual, Chapter 1, “Inpatient Hospital
Services,” §30.1, “Drugs Included in the Drug Compendia,” which also apply to drugs
furnished to SNF inpatients.
However, drugs not included, or approved for inclusion, in the drug compendia are
nevertheless covered in a SNF if such drug:
1. Was furnished the patient during their prior hospitalization;
2. Was approved for use in the hospital by the hospital’s pharmacy and drug
therapeutics (or equivalent) committee;
3. Is required for the continuing treatment of the patient in the skilled nursing
facility; and
4. Is reasonable and necessary.
Under the limited circumstances mentioned in items 1 through 4 above, a combination
drug approved by a hospital pharmacy and drug therapeutics committee may also be
covered as an extended care service.
Rules for drugs and biologicals applicable to hospital inpatients found in the Medicare
Benefit Policy Manual, Chapter 1, “Inpatient Hospital Services,” §§30, 30.3, and 30.5,
also apply to inpatients of SNFs. They are:
• General information concerning drugs and biologicals furnished to inpatients;
• Combination drugs; and
• Drugs for use outside the SNF.
