SNP HEDIS 2008 (Summary) Documentation for Reporting Year 2007
General Information
This documentation presents (1) a description of each of the Special Needs Plan (SNP) HEDIS measures that CMS collected for 340 SNP plan benefit packages (PBPs) for health care provided in calendar year 2007 to Medicare SNP beneficiaries and (2) the location of the rates associated with each SNP HEDIS measure within the HEDIS workbook (HEDIS2008_SNP.XLS). CMS took the description and additional information for each measure from HEDIS 2008 Volume 2: Technical Specifications. This release contains only those rates, percentages, or averages for each measure and not the numerator or denominator used to create those measures.
CMS requires that all managed care organizations undergo an audit on all HEDIS measures. The summary data file includes all submitted data following the audit.
The HEDIS measure descriptions reprinted here are done so with the permission of the National Committee for Quality Assurance (NCQA).

Medicare SNP HEDIS Reporting 
The reporting unit for SNP HEDIS is the PBP. Each Medicare Advantage contract must have at least one PBP; many contracts offer more than one. SNP PBPs limit enrollment to special needs individuals, i.e., those who are dual-eligible, institutionalized, or have one or more severe or disabling chronic conditions. In 2008, CMS collected data from 206 Medicare Advantage contracts for health care delivered by 340 SNP PBPs in 2007. 
The "Service_Area" sheet in the SNP HEDIS workbook identifies the state(s) and counties where services are offered for that PBP.
HEDIS Technical Specifications
The description and related information provided for each measure in this documentation are taken from the HEDIS 2008 Technical Specifications, which are the specific instructions for calculating HEDIS measures that NCQA provides to Medicare managed care plans. For each measure, the Technical Specifications detail the precise method for sampling (when appropriate), identification of the numerator and denominator, measure calculation, and any other important considerations specific to that measure. The Technical Specifications also contain general guidelines that apply to all measures, such as the use of medical records and when a plan should not report a measure because its eligible membership is too small. Some measures require more detailed specifications than others. 
Missing Values
The HEDIS guidelines distinguish between three different types of missing values in the rate field: Not Applicable (NA), No Benefit (NB) and Not Reportable (NR). Health plans report NA when they: do not have a large enough population to calculate a representative rate (e.g., many measures require that rates be based on at least 30 members) or are not eligible for a measure (e.g., a health plan cannot calculate outpatient drug utilization if it does not offer an outpatient drug benefit; a health plan cannot calculate a measure requiring a year of continuous enrollment if its first enrollment began mid-way through the reporting year.) A value of NB is recorded when the health plan did not offer the health benefit required by the measure (e.g., Mental Health/Chemical Dependency). Health plans report NR when: they choose not to calculate and report a rate, or the health plans HEDIS Compliance Auditor determines that a rate is materially biased (applicable only to audited measures). 
For measures reported as a percentage, material bias is defined as a deviation of more than five percentage points from the true rate. For other measures (e.g., procedures per 1,000 member years), material bias exists if the number of counted procedures deviates by more than ten percent from the true number of procedures.

Suppression for Small Number
Under the Privacy Act, CMS cannot publish or otherwise disclose the data in a form raising unacceptable possibilities that an individual could be identified (i.e., the data must not be beneficiary-specific and must be aggregated to a level where no data cells have 10 or fewer beneficiaries). To ensure that no beneficiary can be identified, CMS has chosen not to report certain measures, specifically enrollment by age category, and has suppressed an extremely small number of rates. CMS has replaced suppressed rates with an NA.' Please see the section on missing values above for an explanation of missing value designations.
Additional Variables
CMS includes our record of enrollment as of December of the measurement year in the "GENERAL" sheet in the HEDIS workbook. The HEDIS reported value is adjusted for individuals with partial-year enrollment and reflects the entire contract's enrollment as well as the PBP enrollment.
We have included the Post Balanced Budget Amendment Naming of plan types as well as indicators if the contract offered a Special Needs benefit package or a Part D drug benefit in 2007. These values and others can be found on the sheet named "GENERAL". The full list of fields included on this sheet is described later in this document.
There is a separate sheet called "Service Area" in the SNP HEDIS workbook which contains the contract, state(s) and counties served by the PBPs reporting HEDIS. There is an additional field "EGHP" which indicates if the county is available only to beneficiaries in Employer Groups.
National Enrollment Weighted Average Score
CMS has calculated and included a weighted national average for all of the Effectiveness of Care (EOC) measures. These rates are reported on a separate sheet called "National Rates" in the SNP HEDIS workbook. The rate for each of the EOC measures was calculated using the following formula:
((En1/TotE)*Sn1)+((En2/TotE)*Sn2)++((Enx/TotE)*Snx)=National Enrollment Weighted Average Score
Where:	TotE = Total enrollment for all PBPs with a valid numeric rate in the measure
En1 = Enrollment in the first PBP with a valid numeric rate
Sn1 = Reported rate for the first PBP with a valid numeric rate
Enx = Enrollment in the last PBP with a valid numeric rate
Snx = Reported rate for the last PBP with a valid numeric rate
