Healthcare Software Development Services

HIPAA-compliant custom software for medical practices, specialty groups, and health tech firms. Patient portals, clinical workflows, billing systems, EHR integration. Full code and data ownership.

Healthcare practices arrive at the same custom-software conversation by a familiar path. The EHR handles the clinical record, but every operational system around it has gaps. Patient intake still happens on paper. The patient portal bundled with the EHR sees minimal use because the UX is dated and clients can't see what they actually want. Billing teams catch missed revenue by hand. Referrals are tracked in spreadsheets. Telehealth runs on a generic third-party tool that doesn't integrate with anything. Practice-management workflow lives in someone's head and a half-dozen sticky notes on a monitor.

The major EHRs (Epic, Cerner, Athena, NextGen, Allscripts, eClinicalWorks) are good at the clinical core — they handle the certification requirements, the clinical content libraries, the regulatory submissions that would be expensive to rebuild from scratch. They are not as good at the operational and patient-experience layer that surrounds the core. And the patient-portal and engagement modules they offer, where they exist, are typically generic, weakly branded, and limited.

Aslan builds custom HIPAA-compliant software that sits alongside your EHR — better patient communication, custom intake workflows, specialty-specific tools, automated billing-code analysis, telehealth platforms that actually integrate with your systems. We don't replace what works. We build the operational layer that should have been there, and we deliver the source code and database to your practice when we're done.

Six kinds of healthcare systems we build

Most engagements land in one or two of these patterns. About half of the practices we work with combine two or more into a single platform.

Custom patient portals

Branded patient portals that surface what patients actually want — appointment scheduling, secure messaging, lab results, bill payment, document upload — on your domain, integrated with your EHR or PM system. Pairs naturally with our customer portal development work.

Clinical workflow automation

Custom intake forms, referral tracking, care coordination across multiple providers, treatment protocol checklists, prior-authorization workflows. Replaces the paper-and-spreadsheet systems most practices still run in parallel to their EHR.

Medical billing & coding tools

AI-assisted coding analysis, claims management dashboards, denial tracking, revenue cycle dashboards. The AI proposal analysis pattern adapted for healthcare — find unbilled consultations, flag undercoded encounters, surface reimbursement-cycle outliers.

EHR integration & extensions

Custom modules that plug into Epic, Cerner, Athena, NextGen, eClinicalWorks via HL7 v2, FHIR R4, or EHR-specific APIs. Bridges between the EHR and PM, between PM and accounting, between EHR and patient-facing tools. Often supported by our API development work.

Telehealth platforms

Custom telemedicine where off-the-shelf tools fall short — embedded video, EHR-integrated visit data, specialty-specific workflows (behavioral health intake, dermatology image review), and asynchronous store-and-forward consultations.

Population health & analytics

Practice-level analytics dashboards, quality metrics tracking for MIPS/MACRA, care-gap identification, and operational performance reporting. The reporting layer the EHR can produce in theory but rarely in a usable form.

Custom or Epic / Cerner / Athena / Kareo / DrChrono?

For most practices, the answer is "both, in different layers." Here's the framework.

Keep the EHR / PM for the clinical core when…

  • ONC certification, MIPS/MACRA reporting, and clinical content libraries are handled by the EHR
  • Carrier and payer claim filing flows through the PM system
  • The clinical workflow inside the EHR — chart, orders, e-prescribing — works for your providers
  • Replacing the EHR would cost more than wrapping it for the next 5 years

Build custom for the operational layer when…

  • The patient portal bundled with the EHR is unused or unbranded
  • Patient intake still happens on paper or in a generic form tool
  • Billing leaves consistent revenue on the table due to coding gaps
  • Referral tracking lives in spreadsheets or sticky notes
  • Telehealth runs on a separate tool that doesn't integrate with the EHR
  • Specialty workflows aren't modeled cleanly by the generic EHR
  • You want full code and data ownership for a sale, merger, or buy-up scenario

HIPAA compliance built in, not bolted on

Every healthcare engagement includes these from day one. We sign a Business Associate Agreement before any PHI is shared.

Data encryption

AES-256 encryption at rest and TLS 1.3 in transit for all PHI. Database-level encryption supplemented with field-level encryption for the most sensitive PHI categories.

Access controls

Role-based access with minimum-necessary principles. SSO and MFA for administrative roles. Patient-facing access uses verified-identity flows appropriate to the data sensitivity.

Audit logging

Every PHI access, modification, and disclosure is logged with user identity, timestamp, IP, and action. Logs are retained for the standard HIPAA window and surfaced in audit-ready reports.

BAA-covered infrastructure

Hosting on BAA-covered AWS, Azure, or specialized healthcare clouds. The BAA chain — Aslan to subcontractor to vendor — is intact and documented for your compliance audits.

How we build for healthcare

Every engagement runs through the same five phases. HIPAA testing and BAA setup add a couple of weeks compared to non-healthcare projects.

1. Discovery

Three weeks of mapping your EHR/PM, clinical workflows, billing patterns, and the manual processes that surround them. Interviews with providers, billing staff, and administrators. Compliance posture is decided here. See our discovery phase guide.

2. Integration & compliance design

Plan the EHR integration (HL7, FHIR, or API), the data-flow architecture, the BAA chain, and the audit-logging design. Compliance is a design decision, not a retrofit.

3. Build

Phased implementation with weekly demos. First usable module — typically a patient portal core or a billing-analysis tool — is in front of stakeholders by week 5 or 6.

4. Pilot & security testing

Roll out to a small set of providers, billing staff, or pilot patients. Concurrent security testing — vulnerability scanning, penetration testing, audit-log validation — before broad release.

5. Hand off

Source code transferred to your practice's account. Documentation, including compliance documentation, written for your team. Training. Optional ongoing maintenance with the BAA in force.

What your practice keeps

Especially important for practices considering a future sale, merger, or buy-up.

Full source code

Delivered to a Git repository in your practice's account. The software is an asset on the balance sheet, not a contract that has to be re-negotiated annually.

Full patient data ownership

Your database, your BAA-covered hosting, your backups. We don't hold copies of PHI. We don't aggregate across practices. Your patient data does not become a vendor's product.

No per-user or per-patient fees

Add providers, add staff, add patients — no licensing call. The cost is the cost of HIPAA-grade hosting and optional maintenance, not a per-seat tax on practice growth.

No platform lock-in

Standard, mainstream technology. If the practice is sold or merged, the software travels with it. If you want to hand the codebase to a different developer to maintain, you can. See our software ownership guide for what this means in practice.

AI-Powered Patient Messaging Platform

We built a custom patient communication platform for a multi-provider practice. The system uses AI to classify incoming messages as clinical or administrative, route to the right staff automatically, suggest billing codes for reimbursable consultations, and flag urgent messages for immediate clinical attention.

Common healthcare software questions

How much does custom healthcare software cost?

It depends on what's being built. A focused single-purpose tool — for example, a patient intake portal or a custom referral tracking system — can run from a few thousand dollars. A full custom practice management add-on, multi-module patient portal, or telehealth platform typically starts around $30,000 and scales with scope. HIPAA-compliant infrastructure adds modest costs (encryption, audit logging, BAA-covered hosting) that we bake into every estimate. We scope every project precisely during a paid discovery phase.

How do you handle HIPAA compliance?

HIPAA compliance is built into every healthcare engagement from the start, not added at the end. The standard build includes AES-256 encryption at rest and TLS 1.3 in transit for all PHI, role-based access controls with minimum-necessary principles, comprehensive audit logging of every PHI access and modification, BAA-covered hosting (AWS, Azure, or specialized healthcare hosts), and security testing before deployment. We also sign a Business Associate Agreement as part of every healthcare engagement.

Can custom software integrate with Epic, Cerner, Athena, NextGen, or other EHRs?

Yes. EHR integration is one of the most common reasons healthcare clients hire us. We work with HL7 v2 messaging, FHIR APIs (R4 is the current standard), CDA documents, and EHR-specific APIs where they exist (Epic App Orchard, Cerner's Code/Open Developer Experience, Athena's developer portal). For practices on EHRs without modern API access, we use SFTP file exchange or scheduled exports. The integration approach is decided during discovery based on which EHR you run and what data needs to flow.

Should our practice replace our EHR with custom software?

Almost never — and we'll tell you so honestly. EHRs handle the certification requirements (ONC certification, Meaningful Use, MIPS reporting) and the clinical content libraries that are expensive to rebuild from scratch. What most practices actually need is custom software that sits alongside the EHR: better patient communication, custom intake workflows, specialty-specific tools, automated billing-code analysis, and patient portals that don't feel like the generic EHR-bundled version. We build that layer rather than replacing what works.

Can you build a telemedicine platform for our practice?

Yes. Custom telehealth platforms make sense when you've outgrown Doxy.me / Doximity-class generic tools — particularly if you need to embed video in your patient portal, route visits to specific providers based on insurance or specialty, integrate visit data into your EHR or billing system, or support asynchronous (store-and-forward) consultations. For low-volume, generic telehealth, off-the-shelf is usually cheaper than custom.

How long does a typical healthcare software project take?

Most projects ship in 8 to 18 weeks. A focused tool — a patient intake portal, a referral tracker, a custom dashboard — can be in production within 8 to 10 weeks. A multi-module patient portal, a custom billing or coding system, or a telehealth platform typically takes 14 to 18 weeks, with the first usable version visible to staff in week 5 or 6. Healthcare projects run slightly longer than other industries because HIPAA-specific testing and BAA setup add a couple of weeks.

Will you sign a Business Associate Agreement (BAA)?

Yes, on every healthcare engagement where we handle or have access to PHI. The BAA is standard and is executed before any PHI is shared. Our subcontracted hosting providers (AWS, Azure, others as applicable) also sign downstream BAAs. The BAA chain is intact and documented for your compliance audits.

Who owns the software and patient data when the project is done?

Your practice does. Full source code is delivered to a Git repository in your account. Your database (which contains patient data), your hosting (BAA-covered), your domain. No per-user fees, no per-patient fees, no platform lock-in. If the practice is sold or merged, the software and patient data travel with it. If you want to hand the codebase to a different developer to maintain, that's the design.
