It is not NCQA's policy to dictate an organization's claims submission process. Claims may be corrected or updated as necessary before the HEDIS reporting process begins. However, once the HEDIS reporting process has begun (i.e., the measures' eligible populations are identified and samples are drawn for hybrid reporting), the requirements specified in Volume 2 General Guidelines and Technical Specifications must be followed.
For administrative-only measures, members who meet the eligible population criteria for the measure should remain in the measure. If an organization refreshes data for administrative-only measures, the most accurate and current information must be used for reporting. Additionally, the organization must apply the refresh to all applicable measures.
For hybrid measures, members who are in the denominator due to inaccurate claims data may meet criteria for a valid data error. Valid data errors are identified only for hybrid measures during medical record review and may not be identified using supplemental data. In order to categorize a member as a valid data error (and replace the member with another member from the sample), the chart must show no evidence of the diagnosis and must include evidence to explain or substantiate the data error. As described in General Guideline 40, organizations that elect to refresh data for the sample may not use the refreshed data to change the hybrid sample after it has been selected. The auditor reviews all valid data error exclusions during Medical Record Review Validation.
