Utilization of REMIS for A/B MAC (B) Claims Adjudication
Renal Management Information System (REMIS) determines the Medicare coverage
periods for ESRD patients and serves as the primary mechanism to store and access
information in the ESRD Program Management and Medical Information System
Database. REMIS is used by CMS and the renal community to monitor the Medicare
status, transplant activities, dialysis activities, and Medicare utilization of ESRD patients
and their Medicare provider.
The following fields are contained in the (Dialysis) auxiliary file:
• ESRD Coverage Start Date (The date on which the beneficiary is entitled to
Medicare, in some part, because of a diagnosis of End Stage Renal Disease.)
• ESRD Coverage Source Code (The source of the information that establishes
Medicare-based End-Stage Renal Disease Coverage; A= Part A and Dialysis
Training, B= Part A and Dialyzing (No 3 month wait), C= Part A and 3 months
after Dialysis, D= Part A and Functioning Transplant, E= Part A and Month of
Pre-Transplant Stay, F= Part A and ESRD (Verified Source), Blank= No ESRD
Involvement.)
• ESRD Coverage Termination Date (The date on which the beneficiary is no
longer entitled to Medicare under ESRD Provisions.)
• ESRD Coverage Termination Reason (A code that indicates the reason
Medicare-based End-Stage Renal Disease Coverage was terminated; codes: A=
Month of transplant plus 36 months, B=Last month of chronic dialysis, C= Part A
termination, D=Death, E=ESRD ended: other verified source.)
• ESRD Dialysis Start Date (A date that indicates when ESRD dialysis started.)
• ESRD Dialysis Stop Date (A date that indicates when ESRD dialysis ended.)
• ESRD Transplant Start Date (A date that indicates when a kidney transplant
operation occurred.)
• ESRD Transplant Stop Date (A date that indicates when a kidney transplant
failed.)
The above data elements are in CWF and stored in the dialysis auxiliary file, which can
be used to identify a beneficiary’s ESRD eligibility. This data source will assist carriers
in reviewing overpayment determination and accurately processing claims.
