Medicare Managed Care Manual (Pub. 100-16), Ch. 5 § 30.1
HEDIS® Reporting Requirements
30.1 - HEDIS® Reporting Requirements
(Rev. 117, Issued: 08-08-14, Effective: 08-08-14, Implementation: 08-08-14)
HEDIS® is a trademark product of NCQA. All Medicare Advantage plans must submit
audited summary-level HEDIS® data to NCQA, and this includes cost contracts with
closed enrollment. Patient-level data must be reported to the CMS designated patient-
level data contractor. Information about HEDIS® reporting requirements is posted in
HPMS. During the contract year, if an HPMS contract status is listed as a consolidation,
a merger, or a novation, the surviving contract must report HEDIS® data for all members
of the contracts involved. If a contract status is listed as a conversion in the data year, the
contract must report if the new organization type is required to report.
CMS collects audited data from all benefit packages designated as SNPs and contracts
with ESRD Demonstration Plans that had 30 or more members enrolled as reported in the
SNP Comprehensive Report (which can be found at
http://www.cms.hhs.gov/MCRAdvPartDEnrolData/SNP/list.asp#TopOfPage).
The data collection methodologies for HEDIS® are either the administrative or hybrid
types. The administrative method is from transactional data for the eligible populations
and the hybrid method is from medical record or electronic medical record and
transactional data for the sample.
MAOs new to HEDIS® must become familiar with the requirements for data
submissions to NCQA, and make the necessary arrangements as soon as possible. The
organization should work with an NCQA Licensed Organization
(www.ncqa.org/audit.aspx), to arrange for a HEDIS® Audit and is responsible for
determining fees and entering into contracts. HEDIS® Compliance Audits result in
audited rates or calculations at the measure level and indicate if the HEDIS® measures
can be publicly reported. All HEDIS® measures selected for public reporting must have
a final, audited result. The auditor approves the rate or report status of each HEDIS®
measure and survey included in the audit. For HEDIS® measures, the auditor approves
the rate of report status of each measure and survey included in the audit as follows:
• A rate or numeric result. The organization followed the specifications and
produced a reportable rate or result for the measure.
• Small Denominator (NA). The organization followed the specifications but the
denominator was too small (<30) to report a valid rate.
• Benefit Not Offered (NB). The organization did not offer the health benefit
required by the measure (e.g., mental health, chemical dependency).
• Not Reportable (NR). The organization calculated the measure but the rate was
materially biased, or the organization chose not to report the measure or was not
required to report the measure.
Following are requirements for MAOs with special circumstances:
1. MAOs with Multiple Contract Types - An MAO cannot combine small contracts
of different types, e.g., risk and cost, into a larger reporting unit.
2. MAOs with contract conversions: For HEDIS® measures with a continuous
enrollment requirement and for enrollees who converted from one type of contract
to another (within the same organization), enrollment time under the prior
contract will not be counted.
3. MAOs with New Members “Aging-in” from their Commercial Product Line –
These MAOs must consider “aging in” members eligible for performance
measure calculations assuming that they meet any continuous enrollment
requirements. That is, plan members who switch from an MAO’s commercial
product line to the MAO’s Medicare product line are considered continuously
enrolled. Please read the General Guidelines of HEDIS® Volume 2: Technical
Specifications for a discussion of “age-ins” (see “Members who switch product
lines”) and continuous enrollment requirements.
4. MAOs with Changes in Service Areas - MAOs that received approval for a
service area expansion during the previous year and those that will be reducing
their service area effective January 1 of the next contract and reporting year must
include information regarding those beneficiaries in the expanded or reduced
areas based on the continuous enrollment requirement and Utilization of the
particular measure being reported.
5. HMOs with Home and Host Plans - The home plan must report the data related to
services received by its members when out of the plan’s service area. As part of
the Visitor Program/Affiliate Option (portability), the host plan is treated as
another health care provider under the home plan’s contract with CMS. The home
plan is responsible for assuring that the host plan fulfills the home plan’s
obligations. Plan members that alternate between an MAO’s visitor plan and the
home plan are considered continuously enrolled in the plan.
6. New Contracts - MAOs whose effective date is January 1st of the measurement
year will not report HEDIS® performance measures for the corresponding
reporting year.
7. Non-renewing/Terminating MAOs - Entities that meet the HEDIS® reporting
requirements but which have terminated contracts effective January 1st of the
reporting year will not be required to submit a HEDIS® report or participate in
the Medicare CAHPS® or Medicare HOS surveys.
8. MAOs with Continuing Section 1876 Cost Contracts - For cost contracts, CMS
has modified the list of HEDIS® measures to be reported. Cost contractors will
not report the inpatient Utilization measures. The measures to be reported are
listed on Exhibit I.A. CMS does not require cost contractors to report inpatient
(e.g., hospitals, skilled nursing facilities (SNFs)) measures because MAOs with
cost-based contracts are not always responsible for coverage of the inpatient stays
of their members. Cost members can choose to obtain care outside of the plan
without authorization from the MAO. Thus, CMS and the public would not know
to what degree the data for these measures are complete.
10. Section 1876 Cost Contracts: Cost contracts will provide patient-level data for all
the HEDIS® Effectiveness of Care and the Utilization measures for which they
submit summary level data.
11. Mergers and Acquisitions – An entity that acquires and is novating an existing
Medicare contract must file a HEDIS® report since the membership; benefits and
medical delivery system are essentially unchanged. Therefore, during
negotiations for the acquisition it is essential that parties agree on a method of
data exchange that will permit the acquiring organization to file a HEDIS® report
covering the measurement year in which the transaction occurred. If the Health
Plan Management System (HPMS) contract status is listed as a consolidation, a
merger, or a novation during the measurement year, the surviving contract must
report HEDIS® data for all members of the contracts involved. If a contract
status is listed as a conversion in the measurement year, the contract must report if
their new organization type is required to report.
CMS annually provides guidance in the month of August for the upcoming reporting
year. This information is in an annually-issued HPMS memorandum from CMS, entitled
“Updated Requirements for Reporting of HEDIS®, HOS, and CAHPS® Measures.” All
MA contracts by their specific organization type, are listed, that are required to report
HEDIS®. There is no minimum enrollment requirement for submitting MA HEDIS®.
The HPMS Memorandum provides information about required HEDIS® measures for
reporting, changes in the data specifications, data submission schedule and deadlines, and
instructions about data submission. All MA contracts shall use the annual guidance in
the CMS HPMS Memorandum issued annually in August regarding the HEDIS®
requirements for the upcoming reporting year.
Refer to the annual HEDIS®, Volume 2: Technical Specifications for Health Plans for
measure specifications and general guidelines for calculations and sampling.
Medicare Advantage contracts that are required to report HEDIS® summary-level data
must also provide the patient-level data used to calculate the summary-level data for each
MA contract. Submission of the patient-level HEDIS® data is not required for the SNP-
specific HEDIS® measures.
Reporting HEDIS® for Medicare
All members covered under the contracts listed below are included in Medicare HEDIS®
reporting. CMS communicates directly with all contracted organizations and benefit
plans on HEDIS® reporting requirements (e.g., plan type, enrollment criteria). HEDIS®
reporting is required for:
• Medicare Advantage (MA contracts);
• Section 1876 cost contracts with active enrollment;
• Medical Savings Account (MSA) contracts;
• Private Fee-for-Service (PFFS) contracts;
• Employer/Union Only Direct Contract PFFS contracts;
• Special Need Plans (SNPs) offered by MA contracts;
• Certain demonstration projects.
Exclusions:
The Medicare Hospice benefit is considered a gap in enrollment, and contracts shall
exclude MA members electing the hospice benefit through Traditional Medicare or FFS
Medicare, and choose to remain enrolled in the MA plan, beginning on the date when the
hospice benefits begin.
CMS collects patient-level data with patient-level identifiers for the numerator and the
denominator of each required HEDIS® measure because this allows CMS to match
HEDIS® data to other patient-level data for special projects of national interest and
research, such as an assessment of whether certain groups (e.g., ethnic, racial, gender,
geographic) are receiving fewer or more services than others.
CMS is committed to assuring the validity of the summary data collected before it is
released to the public, and to making the data available in a timely manner for beneficiary
information. MAOs and §1876 cost contracts must submit summary measures, after
completing the NCQA HEDIS® Compliance Audit required by Medicare, by mid-June of
each reporting year. MAOs, including PPO, PFFS, and §1876 cost contracts must submit
HEDIS® patient-level data at the same time. CMS requires the submission of the
following patient-level data on the same date as summary data to ensure that the patient-
level data match the summary data. Auditors will review patient-level data for the
numerator and denominator of audited measures when checking for algorithmic
compliance during the HEDIS® audit. The summary data are sent to NCQA and the
patient-level data are sent only through the designated CMS secure data submission
system to the CMS contractor.
1. Summary Data
a. Required Measures - MAOs that held Medicare contracts in the measurement
year and meet the criteria in the previous section of this chapter must report
summary data for all required HEDIS® measures except for the HOS
measures. The HEDIS® measures Flu Vaccination for Adults 65 and older,
Pneumococcal Vaccination Status for Older Adults, and Medical Assistance
with Smoking and Tobacco Use Cessation are collected through the CAHPS®
survey instrument. MAOs must attempt to produce every Medicare required
measure, and report a numerator and denominator even if the numbers are
small, i.e., the denominator is less than 30.
b. Data Submission - NCQA will annually post Health Organization Questionnaires
(HOQ) on the NCQA Web site in late January. MAOs must accurately complete
the HOQ in order to receive the appropriate Interactive Data Submission System
(IDSS). MAOs must submit HEDIS® results for the measurement year using this
web-based tool.
2. Patient-Level Data - Analysis of data with patient-level identifiers for the
numerator and denominator of each measure allows CMS to match HEDIS® data
to other patient-level data for special projects of national interest and research,
such as an assessment of whether certain groups (e.g., ethnic, racial, gender,
geographic) are receiving fewer or more services than others.
a. Required Measures – MAOs must provide patient-level data identifying the
contribution of each beneficiary to the denominator and numerator of every
required summary measure.
b. Data Submission – Patient-level HEDIS® data are submitted via the CMS
Enterprise FTP client system that contracts use to submit other beneficiary
specific information to CMS. Contracts use their existing system that
connects to the designated CMS secure data transmission system to upload
patient-level data files. The CMS contractor accesses the patient-level data
through the same secure system to perform data validations. Contracts must
retain the data used for reporting for six years. As specified in 42 CFR
§422.504 and §423.505, all MA contracts are required to maintain the privacy
and security of protected health information and other personally identifiable
information of Medicare enrollees. There have been questions expressed
about the provision of behavioral health measures in the patient-level data
files. Contracts are accountable for providing patient-level data, unless
prohibited by State laws. In such cases, contracts must notify CMS with
appropriate documentation of the legal prohibition for consideration.
