The Centers for Medicare & Medicaid Services (CMS) published an interim final rule with comment period entitled “Medicare and Medicaid Programs; Policy and Regulatory Revisions in Response to the COVID-19 Public Health Emergency” (85 FR 19247 through 19253) in the April 6, 2020, Federal Register. Its language supports my legal position that medical assistants are permitted to perform nasopharyngeal swabbing to test for COVID-19.
Note the following excerpts from this CMS rule:
Even if the patient is confined to the home because of a suspected diagnosis of an infectious disease as part of a pandemic event … a nasal or throat culture … could be obtained by an appropriately-trained [sic] medical assistant or laboratory technician. …
… Services furnished by auxiliary personnel (such as nurses, medical assistants, or other clinical personnel acting under the supervision of the [rural health clinic] or [federally qualified health center] practitioner) are considered to be incident to the visit and are included in the per-visit payment.
