· Substantive Update to System Availability Requirements. The weekly system availability requirement was updated across the CAQH CORE Infrastructure Rules including CAQH CORE Health Care Claim (837) Infrastructure Rule from 86% per calendar week to requiring systems to be available 90% per calendar week. Additionally, a new quarterly system availability requirement was added allowing systems 24 additional downtime hours per calendar quarter, in excess of the allowable weekly system downtime or 17 hours (10% system downtime per calendar week).
· Non-Substantive Update to CAQH CORE Connectivity. Per CAQH CORE Certification Policy, CORE-certified entities are required to comply with the most recent published version of the CAQH CORE Connectivity Rule within two years of publication. Therefore, by January 1, 2023, CAQH CORE Connectivity vC4.0.0 will be required for all CAQH CORE Infrastructure Operating Rules. To align the rule requirements with this policy, the connectivity requirement language in the CAQH CORE X Infrastructure Rule was updated to require “most recent published and CAQH CORE adopted version of the CAQH CORE Connectivity Rule.”
· Non-Substantive Update to CAQH CORE Master Companion Guide Template. Past versions of the CAQH CORE Master Companion Guide referenced a specific version of the ASC X12N Implementation Guides, e.g., v5010. However, with the creation of new operating rules such as CAQH CORE Attachments Operating Rules which use a different X12 version, not all operating rules use the same X12 version. To align with the need to address multiple X12 versions and enable greater flexibility, references to a specific X12 version were adjusted to be modifiable in the CAQH CORE Master Companion Guide.
