Billing

This specification defines implementation guidance for billing and financial management within the BioMaxis Billing module. This specification is built on FHIR Version 4.0.1 and primarily utilizes the Account, ChargeItem, and Invoice resources.

Financial Integration Workflow

Overview

​This section defines the interaction between clinical orders (BioMaxis ServiceRequest) and the financial tracking system. This implementation uses the Invoice as the formal transition point between clinical activity and financial liability. The BioMaxis Account serves as a ledger for a Patient and for each Encounter.

The Accounting Logic

• Accrual: ChargeItems track the value of services performed.
• Finalization: When an Invoice is issued, it aggregates ChargeItems. At this moment the Account.balance reflects the formal debt.
• Settlement: An Invoice is balanced when a payment (TODO: Payment resource) is linked to it, subsequently updating the BioMaxis Account net balance.
