Previa

○ Overview

Setting the scene

Previa is a healthcare web platform built to eliminate one of the most persistent operational bottlenecks in modern clinical practice: the prior authorization process. Before a patient can receive certain treatments, medications, scans, or surgical procedures, their insurance company must formally approve the request.

In most healthcare organizations today, that process is still managed through phone calls, faxes, manual paperwork, and disconnected systems, creating delays that affect both staff productivity and patient outcomes.

Previa replaces that fragmented process with a single, structured digital workflow. It brings together patient records, insurance information, diagnosis and procedure codes, AI-generated clinical justification, and direct payer API integration into one connected platform. Clinicians and administrative staff can create, review, submit, and track prior authorization requests without switching between tools, re-entering data, or waiting on hold.

○ The Problem

Prior authorization is breaking clinical operations

Prior authorization was designed as a cost-control mechanism for insurers. In practice, it has become one of the most time-consuming, error-prone, and clinically disruptive processes that healthcare teams deal with every day. Physicians and their staff spend several hours per week on prior authorization tasks alone, most of which add no clinical value.

○ The Goal

Five objectives that shaped the product

Previa was created to make prior authorization faster, more accurate, and significantly less labor-intensive for the healthcare teams that deal with it every day.

○ The Solution

A complete digital workflow for prior authorization

Previa was designed as a full-stack web application with a modern React frontend and a Firebase-powered backend. Rather than improving one part of the process, it covers the entire workflow end to end: patient data, clinical coding, justification generation, payer submission, and status tracking within a single connected product.

○ Product Flow

How a request moves through Previa

The user journey was designed to be intuitive for both clinicians and administrative staff. A staff member logs in, begins a new request, and the system guides them through every required step.

○ Core Features

What we built

• Patient record management: Demographics, insurance details, policy numbers, coverage history, and diagnosis history in one place.
• ICD-10 and CPT code support: Structured search, selection, and validation of diagnosis and procedure codes within the submission workflow.
• FHIR R4 payer integration: Direct API-level electronic submission to major payers including Humana and UnitedHealthcare.
• AI-generated clinical justification: Complete, editable draft letters based on diagnosis, procedure, and clinical parameters.
• Five-step guided submission wizard: Sequential validation of every required element before payer submission.
• Real-time request dashboard: Live status view of all active, pending, approved, and denied requests with filtering and drill-down.
• Notifications and status alerts: Immediate alerts for approvals, denials, or requests for additional information.
• Clinical document storage: Secure upload and attachment of clinical notes, lab results, imaging reports, and referral letters.

○ Technology Stack

Built on a practical, modern foundation

Previa was built on a scalable technology stack designed for healthcare-grade reliability and real-time performance.

Execution constraints we had to solve

○ Why This Matters

Delayed authorization means delayed care

Prior authorization is not just an administrative inconvenience. It is a direct barrier between patients and the care their clinicians have determined they need. Delays in authorization mean delays in treatment. Denied requests, particularly those denied for administrative rather than clinical reasons, add cost and friction to an already complex system.

Previa addresses this problem at the workflow level, automating the parts of the process that should never have required manual effort in the first place: data re-entry, document drafting, status follow-up. By doing so, it returns time to clinical staff, reduces administrative overhead, and most importantly helps get patients to treatment faster.

○ Outcome

From fragmented manual process to guided digital workflow

For teams handling high volumes of authorization requests, the cumulative impact of even modest efficiency gains per request adds up quickly. Fewer hours spent on administration, fewer avoidable denials, and faster turnaround from submission to decision represent meaningful improvements to how a healthcare organization operates.

○ Conclusion

A faster, cleaner, more reliable way to get patients the care they need

Previa is a focused, practical solution to a problem that costs the healthcare industry enormous amounts of time, money, and clinical attention every year. By turning prior authorization from a fragmented, manual process into a guided digital workflow, one that combines patient data management, intelligent code support, AI-assisted documentation, direct payer integration, and real-time tracking, it addresses the problem at every stage rather than just one.

The platform demonstrates how modern web technology and AI can be applied meaningfully to healthcare operations: not to replace clinical judgment, but to eliminate the administrative work that surrounds it and slows it down.

For the healthcare teams that deal with prior authorization daily, Previa offers something straightforward and valuable: a faster, cleaner, and more reliable way to get patients the care they need.
