Definition

ISO-11179 Definition

The two-character USPS state abbreviation representing the state of a health plan member primary residential address. Member state code is used in geographic analytics, state-level Medicaid eligibility determination, CMS county-level capitation rate assignments for Medicare Advantage, and state-mandated benefit compliance reporting. Standard values follow USPS two-letter state codes such as CA, TX, FL, and NY plus US territory codes including PR, GU, and VI.

Healthcare data teams use mbr_state_cd as a geographic partition key in Snowflake and BigQuery to improve query performance on large member tables and support state-level population health reporting.

Why This Term Matters

Member and enrollment data governs who receives care and who pays for it — making it foundational to every downstream healthcare analytics workflow. Data engineers who understand member terminology build eligibility pipelines that prevent coverage gaps, correctly identify dual-eligible members, and support accurate risk adjustment submissions to CMS. Enrollment errors directly affect capitation payments and can trigger CMS corrective action plans.
