A Data Science Perspective:
The Broad Impact of Removing Medical
Debt from Credit Reports
While the CFPB’s approach aims to protect consumers from the adverse eects of medical
debt, its policy change has unintended consequences that extend far beyond individual credit
scores. From a data science and credit modeling perspective, the removal of medical debt
fundamentally disrupts the predictive accuracy of credit scoring models in ways that may not
have been fully considered.
Credit models, including those used by nancial institutions and lenders, are built on hun-
dreds - if not thousands - of attributes derived from consumer credit reports. These attri-
butes are interconnected, meaning that even if an individual data point seems minor, its
removal can cause signicant ripple eects across various predictive factors. While the direct
removal of medical debt from a single credit report may appear to have a negligible eect,
the aggregated impact on model performance is profound.

Alteration of Key Risk Indicators: Attributes summarizing total debt, debt-to-income
ratios, and past delinquencies are often inuenced by medical debt. With medical
debt removed, these attributes shift, sometimes in ways that make consumers
appear less risky than they actually are. This can lead to misclassication of
creditworthiness, with lenders potentially extending credit to consumers who may
have previously been considered high risk.
Compounding Eects in AI and Data Models: Credit scoring and risk assessment
models rely on historical data patterns to make accurate predictions. When a large
percentage of attributes - potentially up to one-third - are suddenly altered, the
historical basis for these models becomes unreliable. AI-driven models, which are
particularly sensitive to shifts in input data, may produce inaccurate risk assessments
as a result.
Reduced Predictive Power for Lenders: Lenders depend on credit models to make
informed decisions about extending credit, determining interest rates, and assessing
risk. With medical debt removed, many traditional risk indicators have been
weakened, potentially leading to an increase in mispriced loans and higher default
rates over time. This could result in lenders tightening credit criteria in response,
which may inadvertantly harm the very consumers the CFPB aims to protect.
The CFPB’s policy change benets some consumers in the short term, however the long-term
consequences of disrupting credit models at scale could outweigh these initial gains.
