Price Transparency Data Lake

2018–present

A data lake and automated pipelines ingesting machine-readable pricing files from 80+ healthcare payers under the federal Transparency in Coverage Act — externally-published data at volume, with automated quality monitoring replacing manual review.

Problem

Under the federal Transparency in Coverage Act, healthcare payers are required to publish machine-readable files of their negotiated rates. “Machine-readable” doesn’t mean uniform: 80+ payer organizations means 80+ different file structures, update cadences, and quirks, published externally with no coordination between sources. Manually tracking whether each one was current, complete, and usable didn’t scale past a handful of payers, let alone the full set.

Approach

Architected a data lake and automated pipelines to discover, acquire, and ingest these files at volume — treating large, messy, externally-published data as the normal case rather than a one-off integration to special-case around. Layered automated data quality metric reporting on top, across every source, so the question stopped being “did someone remember to check source #47 this week” and became a monitored pipeline that surfaces which sources are stale, incomplete, or malformed on its own.

Outcome

Replaced source-by-source manual review — which never actually scaled to 80+ payers in practice — with a monitored pipeline that surfaces data quality problems instead of hiding them until someone stumbles onto a bad file downstream.
