# SAIF.Business.Claim.MedicalBill overview

> **Documentation context:** Packaged Component (NuGet)

This library provides the **medical bill business layer** for workers' compensation claims. Key patterns:

## Purpose

- **Standard BOF business objects** — individual and collection classes for medical bills, services, adjustments, EOB notes, and drug pricing.
- **Stored procedure retrieval** — collections use Oracle stored procedures from `pk82396_medical_bills` for retrieving audit services, EOB notes, and service adjustments.
- **Security-filtered access** — `clsMedicalBillCollection` uses `clsSecurityPrincipal.IsAuthorized()` to check exposure and health-issue access before returning data.
