What is this test?
The Back up NPI Dialysis facility test retrieves the backup National Provider Identifier (NPI) information for dialysis facilities that treat patients with End-Stage Renal Disease (ESRD). The NPI is a unique 10-digit identification number issued to healthcare providers, including dialysis facilities, by the Centers for Medicare & Medicaid Services (CMS). This test specifically retrieves the backup identifier used for administrative, billing, and reporting purposes.
Why is this test important for ESRD patients?
For patients with ESRD who require regular dialysis treatment, proper identification of the dialysis facility is essential for insurance claims, medical records, and care coordination. The backup NPI ensures that even if the primary identifier is unavailable, the facility can still be properly identified in healthcare systems. This is particularly important for patients who may receive treatment at different facilities or during travel.
How is the test performed?
This is not a blood test or physical examination. Instead, it is an electronic lookup in healthcare databases to retrieve the backup NPI number associated with a specific dialysis facility. Healthcare administrators or billing personnel typically order this test when they need to verify or update provider information in medical records or insurance systems.
Reference range
Adult males: 22-198 U/L; Females: 22-198 U/LN/A
No patient preparation required - this is a facility identification code used for ESRD dialysis facility reporting and quality measurement purposes
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This test is primarily important for administrative and billing purposes rather than clinical diagnosis. It ensures that dialysis treatments provided to ESRD patients are correctly attributed to the appropriate facility, which is essential for insurance reimbursement, quality reporting, and patient care coordination. Accurate NPI identification helps prevent billing errors and ensures continuity of care for patients who may receive treatment at multiple locations.
