A CMS EHR Certification ID is a number generated by the Certified Health Information Technology (IT) Product List (CHPL) and used for reporting to CMS. It represents a single product or combination of products in the CHPL. The CMS EHR Certification ID is different from the CHPL product number. In the CHPL, this is the number generated when the hospital/clinician selects EHR Certification ID for a suite of products that make up the hospital's/clinician's EHR solution. If a product changes, then a different CMS EHR Certification ID will be generated. The CMS EHR Certification ID is only unique to the product suite. If two different hospitals/clinicians happen to use the same products, then they will both have the same CMS EHR Certification ID.

CMS requires the CMS EHR Certification ID in several of its quality reporting programs. Check with individual quality reporting programs for requirements.

CMS Help Desks listed on the eCQI Resource Center Contact Us page provide information and assistance regarding eCQMs and tools used in CMS quality reporting programs.

The CMS Measures Under Consideration Entry and/ Review Information Tool (CMS MERIT) is the web-based data collection portal that allows a measure developer to submit candidate measures to CMS for consideration.
