Referring Medicare Patients for Prosthetic Care

Download the Physician Prosthetic Assessment (PPA) Form​Improving Your Patient's Satisfaction

When you refer Medicare patients for prosthetic care, a smooth transition can improve your patient’s experience. In an effort to help reduce the risk of inconvenience, delays and unnecessary cost to your patients, we have included an outline of the five pieces of information needed to ensure the prosthetic notes are corroborated in the medical record.

Simply include the required information in the medical records, or alternatively, use the Physician Prosthetic Assessment (PPA) form. Upon completion of the PPA form, place the original in the medical records and send a copy to the prosthetic provider.

The PPA Form can be easily accessed here or by calling toll free 1-877-442-6437 option 1.

A guideline document for completing the PPA form is available for download here.
