On August 19, 2010, CMS is hosting a Special Open Door Forum conference call on the "Developing Outpatient Therapy Payment Alternatives" (DOTPA) research project.  DOTPA is designed to collect and analyze therapy-related information tied to beneficiary need and the effectiveness of therapy in order to develop alternative payment methods to the current financial cap on outpatient therapy services.  DOTPA intends to enroll providers as data collection sites through the remainder of this year.  The Special Open Door Forum is intended for all institutional and noninstitutional providers of outpatient physical therapy, occupational therapy, and speech language pathology reimbursed under Medicare Part B, along with physicians who refer beneficiaries for outpatient therapy.  The call will provide background on the DOTPA program along with information on the provider enrollment and setup process, training resources, and data collection operations.
