Physician or Allowed Practitioner Certification for Medical and

100 - Physician or Allowed Practitioner Certification for Medical and Other Health Services Furnished by Home Health Agency (HHA) (Rev. 10438, Issued: 11-06-20, Effective: 03-01-20, Implementation: 01- 11-21) A physician or allowed practitioner must certify that the medical and other health services covered by medical insurance, which were provided by (or under arrangements made by) the HHA, were medically required. This certification needs to be made only once where the patient may require over a period of time the furnishing of the same item or service related to one diagnosis. There is no requirement that the certification be entered on any specific form or handled in any specific way as long as the approach adopted by the HHA permits the Medicare contractor to determine that the certification requirement is, in fact, met. A written physician or allowed practitioner's order designating the services required would also be an acceptable certification.
