Medicare Credit Balance Report

What is it?

A Medicare credit balance is an amount determined to be refundable to the Medicare program for an improper or excess payment made to a provider because of patient billing or claims processing errors. Examples of Medicare credit balances include instances where a provider is:

  • Paid twice for the same service either by Medicare or by Medicare and another insurer;

  • Paid for services planned but not performed, or for non-covered services;

  • Overpaid because of errors made in calculating beneficiary deductible and/or coinsurance amounts.

Why do you have to do it?

Medicare requires agencies to submit this report regardless of whether or not there is a balance to be refunded.  You may not have a credit balance due, but it is a necessary requirement that Medicare takes very seriously.  If you fail to submit a Credit Balance (CMS-838) Certification Page and/or identify all provider numbers, your Medicare payments will be suspended as stated in 42 CFR 413.20(e) and 405.370.

Where are the forms located?

Use the following link to obtain the Medicare Credit Balance Report.  If there are no credit balances to report, you’ll only need to complete the Certification page and submit a copy to your MAC.  Subsequent pages include instructions and a Detail Page that you will need to complete if you DO have a credit balance to report.
