PECOS Enrollment

The Provider Enrollment, Chain and Ownership System (PECOS) is an online method for providers to enroll with Medicare. Since January 6, 2014, the Patient Protection and Affordable Care Act requires that physicians and non-physician practitioners enroll in Medicare in order to order and refer services, including clinical laboratory tests, for Medicare beneficiaries. Medicare will not pay for clinical laboratory services unless the physician or non-physician practitioner that ordered the testing is enrolled in PECOS.

As you know, lab testing is vital to patient care. Enroll in PECOS today so you can continue to provide your Medicare patients with quality services from DLO. You can enroll online on the PECOS website at
