October 2025 monthly summary focusing on delivering standardized CMS terminology and provider attribution data, cross-database compatibility, and documentation clarity across the tuva-health/tuva and tuva-health/docs repositories. Key outcomes include the consolidation of loading and seeding for CMS terminology and provider attribution data, with new CSVs and YAML configurations for CMS provider specialty codes, hospital lists, and attribution data; enhanced terminology seeds with richer descriptions; ensured schema consistency for cms_provider_attribution; and robust management of HCPCS data. Also included a documentation fix that clarifies the mapping of source patient identifiers to person_id for claims and clinical data.

July 2025 monthly summary for the tuva-health/tuva project. Focused on core data model and configuration corrections to enhance data integrity and downstream billing/claims accuracy. Delivered two targeted fixes that address data quality and configuration reliability in the core data pipeline: - Fixed data type inconsistency by changing service_unit_quantity from integer to number in core models configuration. - Corrected a typographical alias in dqi_models.yml for claim_coinsurance_amount. These changes reduce runtime validation errors, prevent misconfigurations, and improve data quality across core processes. Business impact: more accurate claim calculations, reduced risk of data-related defects, and smoother deployment cycles. Technical impact: cleaner data schemas, safer configuration, and improved maintainability.
