Medinexa: React Lab-Order Marketplace with EHR Integration

Medinexa connects doctors with diagnostic labs: doctors post lab orders, labs bid on them, and patient data comes straight from the EHR. 99WebSol built it in React with a Node.js API.

About the client

Medinexa is a lab-order platform that brings doctors, diagnostic labs, and insurance payers together. Doctors get competitive pricing on lab tests, and labs get a steady stream of orders.

What we delivered

Separate dashboards for three user roles:

  • Doctor dashboard: patient list, case overview, and a create-case flow with diagnosis (ICD-10), clinical notes, insurance details, priority (routine, urgent, or same-day STAT), and CPT-coded tests
  • Lab dashboard: browse open orders, place bids, and manage accepted work through in progress to completed
  • Bidding: bids calculated from each lab’s pricing against CPT base prices; the doctor compares bids and accepts one
  • Payer dashboard: an insurance view of cases and coverage
  • EHR connection: SMART on FHIR login to import patients from Epic, Cerner, and athenahealth
  • Reference data: searchable CPT codes and medical conditions by category
