Defining Common Terminologies

Regular Chronic Dialysis Began (RCDB) – also known as First Date of Dialysis Ever (FDODE) The first date a person is dialyzed after being diagnosed with ESRD. It is often a date in the hospital and could have occurred in another country. Name has been updated to mirror terminology in the End Stage Renal Disease Medical Evidence Report (CMS2728). When determining if a training will waive a patient’s waiting period, the count starts the first day of the month the patient starts dialysis. It is not a 90-day count from the first day of dialysis, but a 3-month count . PD/ Home Hemo/ Self Care Training in the First Three Months of Treatment Coordination of Benefits Period (COB) Specific set of rules applied by either CMS when Medicare is involved or the individual insurance carriers that determines which insurer is primary, secondary and tertiary: a specific time frame may be included. Acute Kidney Injury (AKI) Previously called Acute Renal Failure (ARF), and is an abrupt or rapid decline in renal function or kidney damage that happened suddenly. Our facilities are chronic-based. Because of this, we are unable to bill Medicare. If an AKI patient is treating in our facility and has Medicare, we may need to bill the hospital where the patient was discharged from, and may require a SPA (Single Patient Agreement).
