CMS Pub. 100-08, ch. 3, § 3.3.1.1
Medical Record Review
This section applies to MACs, CERT, RACs, SMRC, and UPICs, as indicated.
A. Definition
Medical record review involves requesting, receiving, and reviewing medical
documentation associated with a claim.
Medical record review, for the purpose of determining medical necessity, requires a
licensed medical professional to use clinical review judgment to evaluate medical record
documentation.
B. Clinical Review Judgment
Clinical review judgment involves two steps:
1. The synthesis of all submitted medical record information (e.g. progress notes,
diagnostic findings, medications, nursing notes, etc.) to create a longitudinal clinical
picture of the patient; and
2. The application of this clinical picture to the review criteria is to make a reviewer
determination on whether the clinical requirements in the relevant policy have been met.
MAC, CERT, RAC, SMRC, and UPIC clinical review staff shall use clinical review
judgment when making medical record review determinations about a claim.
Clinical review judgment does not replace poor or inadequate medical records.
Clinical review judgment by definition is not a process that MACs, CERT, RACs,
SMRC, and UPICs can use to override, supersede or disregard a policy requirement.
Policies include laws, regulations, the CMS’ rulings, manual instructions, MAC
policy articles attached to an LCD or listed in the Medicare Coverage Database,
national coverage decisions, and local coverage determinations.
C. Credentials of Reviewers
The MACs, MRAC, and CERT shall ensure that medical record reviews for the purpose
of making coverage determinations are performed by licensed nurses (RNs), therapists or
physicians. Current LPNs may be grandfathered in and can continue to perform medical
record review. The MACs, MRAC, and CERT shall not hire any new LPNs to perform
medical record review. UPICs, RACs and the SMRC shall ensure that the credentials of
their reviewers are consistent with the requirements in their respective SOWs.
During a medical record review, nurse and physician reviewers may call upon other
health care professionals (e.g., dieticians or physician specialists) for advice. The MACs,
MRAC, and CERT, shall ensure that services reviewed by other licensed health care
professionals are within their scope of practice and that their MR strategy supports the
need for their specialized expertise in the adjudication of particular claim type (i.e.,
speech therapy claim, physical therapy). RACs and the SMRC shall follow guidance
related to calling upon other healthcare professionals as outlined in their respective
SOWs.
RACs shall ensure that a licensed medical professional will perform medical record
reviews for the purpose of determining medical necessity, using their clinical review
judgment to evaluate medical record documentation. Certified coders will perform coding
determinations. CERT and MACs are encouraged to make coding determinations by
using certified coders. UPICs have the discretion to make coding determinations using
certified coders.
SMRC shall follow guidance related to certified coders as outlined in their
SOW.
D. Credential Files
The MACs, MRAC, CERT, RACs, and UPICs shall maintain a credentials file for each
reviewer (including consultants, contract staff, subcontractors, and temporary staff) who
performs medical record reviews. The credentials file shall contain at least a copy of the
reviewer’s active professional license.
E. Quality Improvement (QI) Process
The MACs, CERT, RACs, and SMRC shall establish a Quality Improvement (QI)
process that verifies the accuracy of MR decisions made by licensed health care
professionals. The MACs, CERT, RACs, and SMRC shall attend the annual medical
review training conference as directed by the CMS and/or their SOW. The MACs, CERT,
RACs, and SMRC shall include inter-rater reliability assessments in their QI process and
shall report these results as directed by CMS.
F. Advanced Beneficiary Notice (ABN)
The MACs, CERT, RACs, UPICs, and SMRC shall request as part of the ADR, during a
medical record review, a copy of any mandatory ABNs, as defined in Pub. 100- 04,
Medicare Claims Processing Manual Chapter 30 section 50.3.1. If the claim is
determined not to be reasonable and necessary, the contractor will perform a face validity
assessment of the ABN in accordance with the instructions stated in Pub. 100-04
Medicare Claims Processing Manual chapter 30 section 50.6.3.
The Face Validity assessments do not include contacting beneficiaries or providers to
ensure the accuracy or authenticity of the information. Face Validity assessments will
assist in ensuring that liability is assigned in accordance with the Limitations of Liability
Provisions of section 1879 of the Social Security Act.
G. MAC Funding Issues
The MAC-medical record review work performed by medical review staff for purposes
other than MR (e.g., appeals) shall be charged, for expenditure reporting purposes, to the
area requiring medical review services.
All medical record review work performed by MACs shall:
• Involve activities defined under the Medicare Integrity Program
(MIP) at Section 1893(b)(1) of the Act;
• Be articulated in its medical review strategy; and
• Be designed in such a way as to reduce its Comprehensive Error
Rate Testing (CERT) error rate or prevent the contractor’s error
rate from increasing.
The MACs shall be mindful that edits suspending a claim for medical review to check for
issues other than inappropriate billing (i.e. completeness of claims, conditions of
participation, quality of care) are not medical review edits as defined under Section
1893(b)(1) of the Act and cannot be funded by MIP. Therefore, edits resulting in work
other than that defined in Section1893 (b) (1) shall be charged to the appropriate Program
Management activity cost center. Activities associated with claims processing edits shall
not be charged to MIP.
H. Review Timeliness Requirements
Prepayment Review Requirements for MACs
When a MAC receives requested documentation for prepayment review within 45
calendar days of the date of the ADR, the MAC shall do the following within 30 calendar
days of receiving the requested documentation: 1) make and document the review
determination and 2) enter the decision into the Fiscal Intermediary Shared System
(FISS), Multi-Carrier System (MCS), or the VIPS Medicare System (VMS). The 30
calendar day timeframe applies to prepayment non-medical record reviews and
prepayment medical record reviews. The 30 calendar day timeframe does not apply to
prepayment reviews of Third Party Liability claims. The MACs shall make and enter a
review determination for Third Party Liability claims within 60 calendar days.
Counting the 30 Calendar Day Timeframe
The MACs and RACs shall count day one as the date each new medical record is
received in the mailroom. The MACs and RACs shall give each new medical record
received an independent 30 day review time period.
Prepayment Review Requirements for UPICs
When a UPIC receives all documentation requested for prepayment review within 45
calendar days of the date of the ADR, the UPIC shall make and document the review
determination and notify the MAC of its determination within 60 calendar days of
receiving all requested documentation. Medical review for the purpose of fraud, waste, or
abuse requires 60 days to allow for the integration of information from the investigative
process. This information may be a result of recent/concurrent investigative actions such
as beneficiary/provider/supplier interviews, site visits and/or receipt of additional
internal/external information.
Post-payment Review Requirements for MACs
The MAC shall make a review determination and mail the review results notification
letter to the provider within 60 calendar days of receiving the requested documentation.
For claims associated with any referrals to the UPIC for program integrity investigation,
MACs shall stop counting the 60-day time period on the date the referral is made. The
60-day time period will be restarted on the date the MAC received requested input from
the UPIC or is notified by the UPIC that the referral has been declined.
For claims sent to MR for reopening by the contractor appeals department, in accordance
with Pub. 100-04, chapter 34, §10.3, begin counting the 60 days from the time the
medical records are received in the MR department.
Post-payment Review Requirements for RACs
When a RAC receives requested documentation for review within 45 calendar days of the
date of the ADR, the RAC shall do the following within 30 calendar days of receiving the
requested documentation: 1) make and document the review determination, and 2)
communicate the results to the provider.
State Laws that Affect Prepayment Review Timeliness Requirements
The MACs shall adhere to state laws that require an evidentiary hearing for the
beneficiary before any denials are processed. The MAC shall review the claim within 30
days, allow the time required for the evidentiary hearing, and then continue with the
processing of the claim on the next business day.
Post-payment Review Requirements for UPICs
To promote the timeliness of the investigative process, the UPICs shall complete post-payment medical review and provide the lead investigator with a final summary of the
medical review findings that includes reference to the allegations being substantiated/not
substantiated by medical review, reasons for denials, and any observations or trends
noted within 60 calendar days, unless otherwise directed by CMS. The counting for the
60-day time period begins when all of the documentation is received by the UPIC. The
UPIC shall have a HIPAA compliant process to receive this documentation that includes
the application of the date the documents are received at the UPIC’s designated mailing
address for all methods described in section 3.2.3.5 of this chapter. The medical review
unit shall communicate the medical review findings in a summary document to the
investigative lead within 60 calendar days of receiving all of the requested
documentation. Medical review for the purpose of fraud, waste, or abuse requires 60 days
to allow for the integration of information from the investigative process. This
information may be a result of recent/concurrent investigative actions such as
beneficiary/provider/supplier interviews, site visits and/or receipt of additional
internal/external information.
If the UPIC is unable to complete the post-payment medical review in 60 days, they shall
document this and the reason for the delay in the UCM and communicate this to their
COR/BFL.
