OASISFlow — OASIS Data Entry and Validation SaaS for Home Health Agencies That Are Still on Paper
Home health agencies submit OASIS assessments monthly through a nightmare of paper forms, manual data entry, and legacy software that looks like Windows XP. OASISFlow gives clinicians a structured digital intake that validates fields in real time, catches submission errors before Medicare rejects them, and exports clean OASIS-D1 files. Your billing coordinator will cry tears of actual joy.

— sourced from real community discussions
OASIS Workflow Coordinator is a dedicated job role at home health agencies because manual form entry into legacy software is time-consuming and error-prone, with Medicare rejections costing agencies real money per incorrect submission.
What is it?
OASIS Workflow Coordinators are a real full-time job because the forms are complex, the validation rules are strict, and legacy agency software makes everything worse. OASISFlow provides a clean web form mapped to every OASIS-D1 field, validates entries against CMS business rules in real time, flags errors before submission, and exports a compliant grouper-ready file. It also tracks submission deadlines per patient and sends reminder alerts so no assessment goes late. Buildable now because the CMS OASIS-D1 field spec is public, validation logic is deterministic (no AI needed), and a Next.js form with Supabase behind it ships in under 3 weeks.
Why now?
CMS updated OASIS-D1 specs in 2023 and most small agencies are still using legacy software that has not kept up, creating a direct pain point that a modern web app can solve with no custom infrastructure.
- ▸OASIS-D1 digital form with real-time CMS validation rules enforced on every field
- ▸Submission deadline tracker per patient with automated reminder emails
- ▸One-click export of completed assessments as grouper-ready text files
- ▸Audit trail showing who entered and modified each assessment with timestamps
Target Audience
Home health agency administrators and billing coordinators at small independent agencies (10-100 patients), roughly 12,000 independent home health agencies in the US.
Example Use Case
Sandra, billing coordinator at a 40-patient home health agency, enters OASIS data for 8 new admissions this week, catches 3 validation errors before submission, and exports clean files to their grouper software — saving 6 hours and one Medicare rejection per month.
User Stories
- ▸As a clinician, I want real-time validation feedback as I fill the OASIS form, so that I fix errors before submission instead of after Medicare rejects the claim.
- ▸As a billing coordinator, I want a deadline tracker for all open assessments, so that I never miss a submission window and face payment delays.
- ▸As an agency admin, I want an audit trail showing who entered each assessment, so that I can meet CMS documentation requirements during audits.
Done When
- ✓Validation: done when entering an invalid OASIS field shows an inline error message and blocks form progression.
- ✓Export: done when clicking export produces a downloadable text file that passes a grouper software import without errors.
- ✓Deadline tracker: done when dashboard shows each patient with a color-coded days-until-due badge updated daily.
- ✓Reminder email: done when coordinator receives an email listing assessments due in 3 days with a direct link to each form.

What's the competition?
Competition Level
Medium
Similar Products
Homecare Homebase (full EHR, $2k+/month, 6-month implementation), Brightree (enterprise-only), PointClickCare (hospital-grade, not for small agencies) — none priced for independent agencies needing just OASIS data entry.
Competitive Advantage
Priced 60% below legacy agency management platforms, requires zero IT setup, and validates against current CMS rules out of the box without a 3-month implementation project.
Regulatory Risks
HIPAA BAA required before any agency uses the product with real patient data. Use Supabase Business plan for HIPAA-eligible infrastructure. Get a standard BAA template from a healthcare attorney ($500-$1,000 one-time cost) before beta.
What's the roadmap?
Feature Roadmap
V1 (launch): OASIS form with validation, deadline tracker, export, reminder emails. V2 (month 2-3): multi-clinician accounts, audit trail. V3 (month 4+): grouper API integration, electronic signature.
Milestone Plan
Phase 1 (Week 1-2): full OASIS form with Zod validation and export live. Phase 2 (Week 3-4): patient queue, deadline tracker, reminder emails live. Phase 3 (Month 2): 3 agencies in paid beta, BAA signed.
How do you build it?
Tech Stack
Next.js, Supabase, Stripe, Resend — build with Cursor for validation logic, v0 for form components, Lovable for dashboard UI
Suggested Frameworks
Next.js App Router, Supabase JS, React Hook Form with Zod validation
Time to Ship
3 weeks
Required Skills
Complex form validation with Zod, Supabase RLS for multi-tenant data, PDF/text file export, scheduled reminder emails.
Resources
CMS OASIS-D1 data specs (public), React Hook Form docs, Supabase multi-tenant patterns, Resend scheduled email docs.
MVP Scope
app/page.tsx (landing), app/dashboard/page.tsx (patient queue + deadlines), app/assessments/[id]/page.tsx (OASIS form), app/api/export/route.ts (text file export), lib/db/schema.ts (patients, assessments, agencies), lib/validation/oasis.ts (Zod OASIS field rules), components/OASISForm.tsx (multi-step form), lib/reminders/scheduler.ts (deadline email logic), .env.example (env vars)
Core User Journey
Add patient -> fill OASIS form with real-time validation -> fix flagged errors -> export grouper file -> mark submitted.
Architecture Pattern
Clinician fills form -> Zod validates each field on change -> completed assessment stored in Supabase -> deadline tracker checks daily via cron -> reminder email sent via Resend -> export triggered -> text file generated server-side -> downloaded by user.
Data Model
Agency has many Users. Agency has many Patients. Patient has many Assessments. Assessment has one ExportRecord. Assessment has many ValidationErrors.
Integration Points
Supabase for database and auth, Resend for deadline reminder emails, Stripe for billing, Vercel Cron for daily deadline checks.
V1 Scope Boundaries
V1 excludes: direct grouper API integration, physician e-signature, scheduling, billing claims, mobile app, multi-location enterprise accounts.
Success Definition
A home health billing coordinator at an agency the founder never contacted signs up, processes 5 real patient assessments, exports clean files accepted by their grouper, and upgrades to paid.
Challenges
Selling into home health agencies requires trust — they are handling Medicare-billed patient data and will ask about HIPAA compliance before signing up. Get a standard BAA template reviewed by a healthcare attorney before your first sales call. Distribution via home health billing consultant networks is faster than SEO.
Avoid These Pitfalls
Do not launch without a signed BAA template ready — even beta agencies will ask on day one. Do not attempt direct grouper software API integration before 10 paying customers confirm they want it. Finding first 10 paying customers will take longer than building — home health agencies move slowly, budget 8 weeks of outreach before expecting a signed deal.
Security Requirements
Supabase Auth with magic link. RLS on all patient and assessment tables scoped to agency. Supabase Business plan for HIPAA eligibility. Input validation on all OASIS fields via Zod. BAA signed with all customers before data entry.
Infrastructure Plan
Vercel for Next.js, Supabase Business plan for HIPAA-eligible Postgres, Resend for email, Vercel Cron for deadline checks, Sentry for errors. Total: ~$90/month at launch.
Performance Targets
30 DAU at launch, 200 req/day. Form validation response under 100ms (client-side Zod). Export file generation under 3 seconds. Page load under 2s.

First Run Experience
On first run: a sample patient with a partially completed OASIS assessment pre-loaded in demo mode. User can immediately fill remaining fields, see real-time validation errors, and export a sample file without entering real patient data. No manual config required: demo patient loads on signup, export works without any integration setup.
How to build it, step by step
1. Map all OASIS-D1 fields to a Zod schema in lib/validation/oasis.ts using the public CMS data specs. 2. Run npx create-next-app with TypeScript and Tailwind. 3. Build Supabase schema for agencies, users, patients, assessments in lib/db/schema.ts. 4. Build multi-step OASISForm.tsx using React Hook Form with Zod validation showing real-time error messages. 5. Build patient queue dashboard in app/dashboard with deadline countdown badges using v0. 6. Create export route in app/api/export/route.ts that generates a CMS-compliant text file from assessment data. 7. Add Vercel Cron job that runs daily to find assessments due in 3 days and sends reminder emails via Resend. 8. Add Supabase Auth with magic link and RLS on all patient and assessment tables. 9. Add Stripe subscription billing in app/api/checkout/route.ts. 10. Deploy to Vercel, walk full journey from adding a patient to exporting a validated file without any manual steps.
