Step-by-step technical breakdown of bidirectional claim execution — from HIS request transformation via HAPI FHIR to Keycloak-secured NHA network transmission and instant response callbacks.
Step 01
Connect your Hospital Information System via pre-built connectors or REST API. Keycloak handles authentication automatically. The configuration wizard completes in under 30 minutes.
Step 02
Register NHCXoperator credentials and select target payers/insurers. Multi-payer routing, failover, and retry policies are completely automatic.
Step 03
Provider HIS → Nexa Adapter → NHCX Network → Payer/Insurer. Handles FHIR R4 transformation via HAPI FHIR, NHA profile validation, and NHA-spec digital signing automatically.
Step 04
Payer/Insurer → NHCX Network → Nexa Adapter → Provider HIS. Adjudication results, pre-auth approvals, and payment confirmations are pushed back in real time via webhooks.
Step 05
Track every claim through its full lifecycle. AI pre-screening catches likely rejections prior to submission, paired with automated compliance reports for NHA and regulators.
Automatic validation, payload encryption, multi-tenant routing, and webhook delivery happen seamlessly behind the scenes.
Every request to and from the NHCX network is secured with mutual TLS and NHA OIDC tokens.
Incoming and outgoing claims are validated against NHA FHIR profiles prior to transmission.
Redis-backed event processing pushes claim updates back to provider HIS in real time.
