(i) Clinical laboratory services.
(ii) Physical therapy, occupational therapy, and outpatient speech-language pathology services.
(iii) Radiology and certain other imaging services.
(iv) Radiation therapy services and supplies.
(v) Durable medical equipment and supplies.
(vi) Parenteral and enteral nutrients, equipment, and supplies.
(vii) Prosthetics, orthotics, and prosthetic devices and supplies.

(2) Except as otherwise noted in this subpart, the term “designated health services” or DHS means only DHS payable, in whole or in part, by Medicare. DHS do not include services that are paid by Medicare as part of a composite rate (for example, SNF Part A payments or ASC services identified at § 416.164(a)), except to the extent that services listed in paragraphs (1)(i) through (1)(x) of this definition are themselves payable under a composite rate (for example, all services provided as home health services or inpatient and outpatient hospital services are DHS). For services furnished to inpatients by a hospital, a service is not a designated health service payable, in whole or in part, by Medicare if the furnishing of the service does not increase the amount of Medicare's payment to the hospital under any of the following prospective payment systems (PPS):
(i) Acute Care Hospital Inpatient (IPPS);
(ii) Inpatient Rehabilitation Facility (IRF PPS);
(iii) Inpatient Psychiatric Facility (IPF PPS); or
(iv) Long-Term Care Hospital (LTCH PPS).
