Introduction

Healthcare claims represent requests for payment for services rendered. They connect members, providers, benefits, and financial systems. Poor claims modeling leads to incorrect payments, regulatory risk, and provider dissatisfaction.

A strong logical data model provides structure, clarity, and auditability across the entire claims lifecycle.

What Is a Healthcare Claim?

A healthcare claim is a formal request submitted by a provider to a payer for reimbursement.

Claims answer:

Who received care?
Who delivered care?
What service was performed?
When did it occur?
What amount is payable?
