Overview

Medical charges feel like a black box to the people paying them. I built a model that not only predicts cost but explains it — because in healthcare, a number without a reason isn't trustworthy.

I engineered features from demographic and clinical factors, then trained interpretable regression models, prioritizing transparency over a marginal accuracy gain. Every prediction comes with the top drivers pushing it up or down.

Packaged behind a simple interface, this is the engine a quoting, budgeting, or planning tool would run on — giving payers and patients a defensible estimate instead of a surprise bill.

At a glance

OPPORTUNITY

Payers and patients struggle to anticipate medical charges, making budgeting and pricing opaque.

WHAT I BUILT

An interpretable regression model that quantifies how demographics and clinical factors drive cost.

IMPACT

A transparent cost estimator that surfaces the top drivers — directly usable in a quoting or planning tool.

Highlights

  • Feature engineering across demographic and clinical signals
  • Interpretable regression with per-prediction driver breakdowns
  • Validated for transparency, not just headline accuracy
  • Designed to plug into a quoting or planning product
