Medicare Program Integrity Manual (Pub. 100-08), Ch. 3 § 3.7.1.1
Provider Error Rate
3.7.1.1 - Provider Error Rate
(Rev. 738; Issued: 08-18-17; Effective Date: 09-19-17; Implementation Date: 09-19-
17)
This section applies to MACs.
If the MAC identifies a provider-specific problem, the provider error rate is an important
consideration in deciding how to address the problem. For instance, a provider with a low
error rate with no history of patterns of errors may require a fairly minor corrective action
plan such as education with recoupment of overpayment. Other factors such as the total
dollar value of the problem and the past history of the provider also deserve
consideration. The MAC assesses the nature of the problem as minor, moderate or major
and uses available tools such as data analysis and evaluation of other information to
validate the problem.
A. Provider Error Rate Formula
The MACs shall include claims denied due to no response to ADRs when calculating the
provider error rate.
The MACs shall use the following formula for prepayment review to calculate the
provider’s service specific error rate:
Total Dollar amount of allowable** charges for services billed in error as determined by
MR***
Total Dollar amount of allowable** charges for services subject to a medical review
documentation request
For postpayment review, the MACs shall use the following formula to calculate the
provider’s service specific error rate:
Total Dollar amount of services paid in error as determined by MR***
Total Dollar amount of services subject to a medical review documentation request
**If allowable charges are not available, submitted charges may be used until system
changes are made.
***Net out (subtract) the dollar amount of charges under billed
