CMS has announced that the CY 2016 provider enrollment application fee is $554, up slightly from $553 in 2015. This application fee is required for institutional providers that are initially enrolling or revalidating enrollment in the Medicare or Medicaid program or the Children’s Health Insurance Program (CHIP) or adding a new Medicare practice location on or after January 1, 2016 and on or before December 31, 2016. Note that CMS uses a broad definition of institutional entities subject to the application fee; it applies to “[a]ny provider or supplier that submits a paper Medicare enrollment application using the CMS-855A, CMS-855B (not including physician and non-physician practitioner organizations), CMS-855S, or associated Internet-based PECOS enrollment application,” along with additional categories of Medicaid-only and CHIP-only institutional providers. CMS estimates that approximately 55,000 Medicare institutional providers and 30,000 Medicaid and CHIP institutional providers will be subject to an application fee in CY 2016.
