Provider data management is one of the most operationally complex data domains in healthcare because providers move, merge, and update their credentials continuously. A data engineer who understands provider terminology can build NPI validation, credentialing, and network adequacy pipelines that keep provider directories accurate and prevent claim rejections. Stale or incorrect provider data is a leading cause of prior authorization delays and CMS compliance findings.

• Provider data management and credentialing workflows
• Network adequacy analysis and directory accuracy
• NPI validation and NPPES registry reconciliation
• Provider master data management (MDM)
• Payer-provider contract and fee schedule management
• Epic SER provider master and Cerner provider registry reconciliation pipelines
• Snowflake provider dimension table design with SCD Type 2 historical tracking
• Databricks NPPES data pipeline for weekly registry refresh and provider MDM updates

• NPI numbers fail the Luhn check-digit test in approximately 1–2% of raw feeds — implement Luhn validation as a mandatory data quality gate before loading provider records into Epic or Cerner integration tables.
• Provider taxonomy codes (NUCC) are updated annually — maintain a versioned reference table with effective dates and validate incoming codes against the current NUCC taxonomy file in your Snowflake provider master.
• Provider address data degrades rapidly: CMS estimates 15–20% of NPPES addresses become outdated within 12 months — schedule quarterly NPPES reconciliation jobs in Databricks to refresh your provider master data.
