ESRD Facilities: CMS Flexibilities to Fight Covid-19 (3/28/20)

Dialysis Patient Care Technician Certification: CMS is modifying the requirement at 494.140(e)(4) for patient care dialysis technicians which requires certification under a State certification program or a national commercially available certification program within 18 months of being hired as a dialysis patient care for newly employed dialysis patient care technicians. We are aware of the challenges that technicians are facing with the limited availability and closures of testing sites during the time of this crisis. CMS will allow patient care technicians to continue working even if they have not achieved certification within 18 months of hire or have not met on time renewals. Click for the full report.

ESRD Federal Regulations

The new ESRD Rules & Regulations approved by the Centers for Medicare & Medicaid Services (CMS) have been submitted to the Office of the Federal Register for publication and have recently been published with comments in the Federal Register (4-15-08). It is currently a 116-page document (see CMS ESRD Final Rules). The rules that apply to certification start on page 20425.

Policy & Timeline
Here is the exact wording related to the timeline for Dialysis Technicians to have certification:

Patient care dialysis technicians (must) be certified under a state certification program or a national commercially available certification program as follows:

  1. For newly-employed patient care technicians(certified) within 18 months of being hired as a dialysis patient care technician.If a newly hired PCT stops working before they have 18 months of experience, they can start working at another facility but the experience from their first job will be added to their new job. For example: A PCT works in Facility “A” for 7 months. Then, he/she has to move to another state. Once Facility “B” hires this person, he/she will have 11 months to become certified.
  2. For patient care technicians employed on or before October 14, 2008 — (certified) within 18 months after such date.” (This means that you will have until April 14, 2010 to be certified.)
    BONENT Certified Members:

    • NOTE: If you are a patient care technician currently employed in dialysis and have a current BONENT certification, you will NOT need to re-take the exam. But, BONENT will not be able to verify your certification to employers or state boards unless your annual certification fees are up-to-date.

State Mandates for Certification

In several states, BONENT certification or state certification is required for technologists/technicians who perform certain patient care procedures. It is incumbent upon all applicants to familiarize themselves with any state licensure requirements for the state in which they intend to be certified. For instance, Ohio certification requires that all applicants have completed one year of patient care prior to the administration of the examination. Other states may have similar requirements.
