The payment deadline date for a primary insurance policy holder. Used to track temporal information related to subscriber due date. This field is commonly used in electronic health records (EHR), healthcare information systems (HIS), and clinical data warehouses for subscriber management and reporting.

CREATE TABLE healthcare_data (
  record_id   VARCHAR(50)   NOT NULL,
  subscriber_due_date DATE,  -- subscriber due date (date only, no time)

Column names follow the ISO-11179 naming convention: lowercase, underscore-separated, using the standard abbreviation as a prefix where applicable.

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.

• Epic ADT feed parsing for real-time member eligibility updates
• Snowflake member dimension table with SCD Type 2 for full enrollment history
• Databricks streaming enrollment reconciliation pipeline for CMS capitation reporting

• Member ID formats vary significantly across payers and source systems — standardize to a consistent composite key (payer_id + member_id) in your Snowflake member master to support cross-payer analytics.
• Enrollment gaps (periods with no active coverage) must be distinguished from true terminations — model using effective_start_dt and effective_end_dt with explicit gap-detection logic rather than a single status flag.
• Duplicate member records are common when members re-enroll after coverage gaps — implement probabilistic matching on (last_name + dob + gender + zip) to link records to a single master member ID in your MDM layer.
