Prevent Interruptions in Physical Therapy Act of 2014 - Amends part B (Supplementary Medical Insurance) of title XVIII (Medicare) of the Social Security Act to require physical therapists furnishing outpatient physical therapy services to use specified locum tenens arrangements for payment purposes in the same manner as such arrangements are used to apply to physicians furnishing substitute physicians services for other physicians.
(Locum tenens [place holder], or substitute, physicians usually assume professional practices in the absence of a regular physician for reasons such as illness, pregnancy, vacation, or continuing medical education.)
