Healthcare Software Development Services

Healthcare software development is different from other software work. The data is protected health information, the users are busy clinicians and anxious patients, and every feature touches a workflow that already exists on paper or inside an EHR. PS3G builds patient and provider apps, portals, telehealth, scheduling and intake tools, remote-monitoring dashboards, EHR integrations and analytics for organizations of every size: a solo practice that needs a digital intake form, a health-tech founder with a first version to ship, a medical-device company that needs a companion app, or an IT department inside a hospital group or payer that needs a tool that will pass security review. We also build and run our own regulated product, so the controls you need are habits for us, not a checklist.

Built by a team that runs its own HIPAA-regulated platform

Most software companies that offer healthcare work have built something for a covered entity. Fewer have operated as a business associate for years with their own product. We built and run our HIPAA-compliant EHR and telehealth platform, DocVilla, which is used by medical practices across multiple states. We hold the PHI, sign the business associate agreements, answer the customer security reviews, keep the audit logs and take the support call when a clinician cannot find a chart before the first appointment of the day.

That experience changes how we build for you. The PHI-handling decisions have been made once and documented. We have a reference architecture for encryption, access control and logging that has survived real customer scrutiny. We know that a visit is a chain of events (a schedule slot, an intake, a note, an order, a result, a claim) and that software which breaks one link gets abandoned by the front desk within a week.

The rest of the firm backs that up: more than ten years in business, a US headquarters in Wilmington, Delaware with an India delivery center, Microsoft and open-source certified engineers, a testing center of excellence, and connected-device work such as our IoT fall-detection footwear for seniors.

Who we work with

The engineering is the same for every client. The engagement is scoped to your size and your regulatory position.

• Clinics and medical groups. A single-location practice replacing paper intake, or a multi-site group that needs a patient portal, online scheduling and a reporting layer across locations.
• Health-tech founders. A first version that has to be HIPAA-ready on day one, built on a stack that a future engineering team can take over, with the documentation an investor or a hospital procurement team will ask for.
• Medical-device and digital-health companies. Companion apps, clinician dashboards and cloud back ends for connected devices. Where the software is itself a medical device, we work inside your design-control process and produce the lifecycle documentation your regulatory consultant needs.
• Payers and benefits administrators. Member portals, eligibility and claims integrations, care-management tools and analytics that join clinical and financial data.
• Labs and imaging centers. Order and result interfaces with referring practices, result portals for patients, and integration with the EHRs your clients already use.
• Departments inside large health systems. A department-level application that must integrate with the enterprise EHR and pass the central IT security and procurement review. We work inside those rules.

What we build

Patient and provider apps

Native iOS and Android apps, or cross-platform apps in React Native or Flutter when one codebase makes sense. Healthcare mobile app development adds requirements of its own: encrypted on-device storage, biometric sign-in with short session timeouts, push notifications that carry no PHI, and app-store health-data disclosures. See our mobile app development services for the platform choices.

Patient portals and provider portals

Patient portal development covers appointment requests, secure messaging, results release with provider control, forms, statements and payments, and proxy access for parents and caregivers. Referral portals give outside clinicians a controlled view of shared patients.

Telehealth and telemedicine software

Video visits with a virtual waiting room, consent capture, screen sharing, asynchronous messaging and visit notes that land in the chart. Telemedicine app development also means choosing a video provider that will sign a BAA and designing for poor connections. Our telemedicine app development guide walks through the feature list and the compliance questions.

Scheduling and digital intake

Online booking with provider-specific rules, reminders by text and email, insurance capture, and intake forms that write structured data (allergies, medications, history, screening scores) into the chart instead of a PDF.

Remote patient monitoring dashboards

Ingestion from Bluetooth devices, Apple HealthKit, Android Health Connect or cellular hubs; threshold rules and alert queues for care teams; time and activity logs for care programs; and patient-facing views that show trends without diagnosing.

EHR integrations via HL7 v2 and FHIR

Interfaces that exchange patient demographics, appointments, orders, results, documents and charges with the EHRs your clients run, using HL7 v2 messaging, FHIR R4 APIs and SMART on FHIR apps. Our API development and integration services cover the non-clinical systems around them.

E-prescribing integrations

Connections to certified e-prescribing networks for new prescriptions, refills and medication history, including the identity-proofing and two-factor authentication steps that electronic prescribing of controlled substances requires. Check the current DEA requirements for your workflow; we build to them.

Billing and claims integrations

Eligibility checks (270/271), claim submission (837P and 837I), remittance posting (835) and claim status (276/277) through clearinghouses, plus patient statements and payment processing that keeps card data out of your application through tokenization.

Analytics and reporting

Operational dashboards, quality-measure reporting, population views and de-identified data sets for research or product analytics, built on a data governance foundation so that definitions, ownership and access rules are agreed before the first chart is drawn.

HIPAA by design

HIPAA compliant software development is not a final review. It is a set of decisions made during design and verified during testing. Our baseline for every healthcare build:

• PHI mapping. A data-flow diagram and a field-level inventory of where PHI is created, stored, transmitted and deleted, including every third-party service that touches it.
• Access control. Unique user identities, role-based permissions, emergency (“break-glass”) access with review, automatic logoff, multi-factor authentication for staff, and the minimum-necessary principle applied to each screen and API.
• Encryption. TLS for every connection, encryption at rest for databases, files and backups, managed keys with rotation, and encrypted on-device storage in mobile apps.
• Audit logs. Who viewed, created, changed or exported which record and when, written to tamper-evident storage, retained according to your policy, and reviewable by your privacy officer without a developer.
• BAAs. A business associate agreement between us and you, and one with every subprocessor (cloud, email, SMS, video, analytics, support tooling). No PHI goes to a vendor that will not sign.
• Risk assessment. A documented Security Rule risk analysis for the system, repeated when the architecture changes, with findings tracked to closure. Our HIPAA compliance consulting team can run this for your whole organization, not only the software we build.
• Secure development. Threat modeling, dependency and container scanning, penetration testing before launch, synthetic data in every non-production environment, and no PHI in logs, crash reports or analytics events.

The HHS Security Rule guidance and NIST’s implementation guide for the Security Rule are the references we design against; check the current official text, because the rules and their guidance are updated. This is general information, not legal advice.

Interoperability: HL7, FHIR, HIE and consumer health platforms

Healthcare software that cannot exchange data with the systems around it becomes a silo that staff work around. We build EHR integration services on the standards EHRs actually support.

Standard	What it carries	Typical use in a project
HL7 v2	Pipe-delimited messages: ADT (admissions, discharges, transfers and demographic updates), SIU (scheduling), ORM (orders), ORU (results), DFT (charges), MDM (documents), over MLLP connections	Real-time feeds from a hospital or practice EHR into your application, usually through an interface engine such as Mirth Connect
FHIR R4	RESTful JSON resources: Patient, Practitioner, Encounter, Appointment, Observation, Condition, MedicationRequest, AllergyIntolerance, Immunization, DiagnosticReport, DocumentReference	Reading and writing data through the standardized API that certified EHRs expose; SMART on FHIR apps that launch inside the EHR; bulk export for analytics
C-CDA and Direct	Structured clinical summary documents and secure point-to-point messaging between provider organizations	Transitions of care, referrals, document exchange with practices that have no API program
HIE networks	Patient discovery and document query across organizations through regional HIEs and national frameworks such as Carequality, CommonWell, eHealth Exchange and TEFCA	Pulling outside records for a new patient; contributing encounter data back to the community record
X12 EDI	Eligibility (270/271), claims (837), remittance (835), claim status (276/277)	Billing and payer integrations through clearinghouses
Apple HealthKit and Android Health Connect	Device and app health data on the patient’s phone, with patient-granted permissions	Remote monitoring, wellness and chronic-care apps

HL7 integration and FHIR integration services both need the same preparation from you: a named contact at the EHR vendor, a test environment, sample messages or API access, and a decision on patient matching. Our EHR integration guide explains the differences, the common data flows and what to prepare.

AI in healthcare software, governed

Healthcare AI solutions that reach production share a pattern: a narrow, well-defined task, a model that never sees PHI outside a BAA, and a clinician who stays in control. Use cases we build include visit and chart summaries, document classification for inbound faxes and scans, drafting replies to routine patient messages, intake triage assistants, and anomaly flags on remote-monitoring data.

Every AI feature we ship comes with its governance: a model and vendor inventory, data-handling rules (no training on your data, no PHI sent to vendors without a BAA), human review before anything reaches a patient or a chart, logging of inputs and outputs, bias and performance checks, and alignment with the NIST AI Risk Management Framework. Our AI governance services set that up; our AI development services build the feature. We have shipped AI inside DocVilla ourselves, including patient summaries generated from encounters the provider selects and reviews, so we know where the sharp edges are.

Our process

1. Discovery. We map the workflow with the people who do it (front desk, clinicians, billing, patients), inventory the PHI and the integrations, and confirm regulatory scope: covered entity, business associate, device software, or a consumer wellness app outside HIPAA but inside the FTC’s rules.
2. Design. Clickable prototypes tested with real users, an architecture document with the PHI data-flow map, and accessibility built in from the first screen.
3. Build. Short iterations with a working demo at the end of each, a secure development lifecycle, and code you own from the first commit.
4. Test. Our testing center of excellence runs functional, automated, performance and security testing, plus interface testing with synthetic HL7 messages and FHIR test servers.
5. Launch. A go-live plan with staff training, BAAs confirmed, monitoring and alerting switched on, and a rollback path.
6. Run. Maintenance, patching, monitoring and support under defined SLAs, by the same team or yours.

Engagement models

• Fixed-scope project. A defined deliverable and price: a patient app, a portal, an integration, a telehealth module.
• Dedicated team or staff augmentation. Healthcare-experienced engineers, testers and integration specialists who join your team monthly and scale up or down.
• Managed services. We run and support the application under an SLA, including the interfaces and the vendor relationships.
• Advisory. Healthcare IT consulting: architecture review, HIPAA readiness, integration strategy, build-versus-buy decisions, or a fractional CTO for a health-tech founder.

How we start: a first conversation, a short assessment, a written proposal.

Case study: DocVilla

DocVilla is the product we built and operate for US medical practices: cloud EHR charting, telehealth video visits, scheduling, a patient portal, e-prescribing, eFax and billing tools, with patient-facing mobile apps. It runs on a Microsoft and open-source stack that we operate ourselves. Building it taught us what clinicians will and will not tolerate in a user interface, how EHR software development has to handle audit, consent and release-of-information rules, and how to keep a regulated SaaS platform running day after day.

Frequently asked questions

What does a healthcare software development company do differently from a general software firm?

The engineering disciplines are the same, but the constraints are stricter. A healthcare team maps PHI before writing code, designs access control and audit logging as core features, signs a business associate agreement, tests with synthetic data, and knows the integration standards (HL7 v2, FHIR, X12) that connect a new application to an EHR or a payer. It also knows clinical workflow well enough not to add clicks to a clinician’s day.

Do you sign a business associate agreement?

Yes. When our work involves access to protected health information, we sign a BAA with you before any PHI is shared, and we require one from every subprocessor we bring into the architecture. We operate as a business associate for the practices that use DocVilla, so the agreement and the controls behind it are part of how we already run.

Can you integrate a new application with the EHR we already use?

In most cases, yes. The method depends on what the EHR exposes: an HL7 v2 interface through an interface engine, a FHIR R4 API, a SMART on FHIR app launch, a C-CDA document exchange, or a vendor-specific API. We start by confirming with the vendor what is available in a test environment, then design the data flows and the patient-matching rules around it.

Is HIPAA compliant app development more expensive than a standard app?

It adds work in specific places: encrypted storage, authentication and session handling, audit logging, a PHI data-flow review, security testing and the vendor agreements for every third-party service. Those items are scoped and priced in the proposal rather than discovered late. We do not publish rates; a first conversation and a short assessment produce a fixed-scope quote.

Can you build a telehealth app that connects to our scheduling and charting?

Yes. Telehealth software is most useful when the visit starts from the schedule, the consent is recorded, the note and any orders land in the chart, and the charge reaches billing without re-entry. We build the video and messaging layer with a provider that signs a BAA and connect it to your EHR through its interfaces or, if you use DocVilla, directly within the platform.

Do you offer healthcare IT consulting without a development project?

Yes. Advisory engagements include architecture and security reviews of an existing application, HIPAA readiness assessments, integration strategy for a product entering the US market, build-versus-buy analysis, and fractional CTO support for health-tech founders. Many consulting engagements end with a roadmap you can execute with your own team.
