out of pocket maximum

The upper limit value for a patient paid amount. Used in healthcare data management and clinical workflows. This field is commonly used in electronic health records (EHR), healthcare information systems (HIS), and clinical data warehouses for out of pocket management and reporting.

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

Claims data is the financial backbone of the US healthcare system, and understanding claims terminology is essential for building accurate revenue cycle and reimbursement analytics. Data engineers who know this terminology can correctly parse 837 transactions, identify adjudication errors, and model denial patterns that represent real revenue recovery opportunities. A single misunderstood claims field can result in millions in underpayments identified only after external audits.

• Claims adjudication and remittance processing
• 837P/837I/837D claim file parsing and validation
• Revenue cycle management and denial analytics
• CMS cost report and Medicare cost reporting
• Payer contract performance and underpayment analysis
• Snowflake claims data mart design with adjudication and remittance fact tables
• Epic Resolute and Cerner Revenue Cycle claims data extraction and normalization
• Databricks Delta Lake incremental load pipelines for high-volume 837 claim processing

• Duplicate claims are endemic in raw 837 feeds — deduplicate on a composite key of (claim_id, service_date, billed_amount, provider_npi) before loading into your Snowflake or Databricks claims data warehouse.
• ICD-10-PCS procedure codes are often confused with ICD-10-CM diagnosis codes in source data — validate code format and route to the correct column based on claim loop position (loop 2300 vs. 2400).
• Adjudication and paid date sequencing errors occur due to batch processing lag — enforce a pipeline rule that adjudication_dt ≥ service_dt and paid_dt ≥ adjudication_dt as a quality check before reporting.
