What InterData Praxiscomputer does
InterData Praxiscomputer GmbH is a privately held, owner-operated German software vendor headquartered in Greven, North Rhine-Westphalia, founded in 1990 and operating for over 25 years in the German healthcare IT market. The company develops and sells InterARZT, a Windows- and Linux-compatible practice management system (PVS / Praxisverwaltungssystem) for ambulatory physicians, serving approximately 800 doctors across the Kassenärztliche Vereinigungen of Westfalen-Lippe, Niedersachsen, and Nordrhein. InterARZT integrates the full suite of German telematics infrastructure (TI) applications — including ePA, ePrescription, eAU, KIM, KV-Connect, NFDM, and eMP — and holds the most gematik / KBV certifications of any regional provider in KV Westfalen-Lippe. The company also operates InterData HMS, a maritime medical software product installed across the AIDA and TUI Cruises fleets (16 ships), and bundles DGN TI hardware (Secunet Konnektor, GUSbox router, card terminals) as a DGN TI Starterpaket integrator.
The company runs an exclusively direct-to-customer go-to-market: no resellers, no distribution partners, with on-site field installation, remote-desktop support, and a Premium service tier. Revenue is generated from InterARZT license and recurring maintenance (pricing not publicly disclosed; DGN KIM priced at €6.55/month/practice), from HMS licensing to cruise line operators, and from ancillary TI hardware bundling and installation services. The company is a 50% subsidiary of DGN Deutsches Gesundheitsnetz Service GmbH and a member of the GUS independent software vendor network, with managing directors Dirk Fellenberg and Armin Flender leading a team of approximately 20 staff. InterData has consistently participated in gematik pilot projects (NFDM-Sprint, ePA, KIM field test) and ranks in the top 15 of German practice software by Net Promoter Score in the ZI survey, with a >80/100 score in the 2026 ZI performance ranking.

Revenue model
- InterARZT Practice Management Software License and Maintenance: InterData generates revenue from the sale and ongoing maintenance of its InterARZT practice management software. The software is provided with regular updates (online), support, and access to the full suite of TI-integrated modules (ePA, eAU, ePrescription, KIM, etc.). Revenue is recurring in nature via maintenance/updates. No public pricing is listed; sales are direct and likely subscription or license-based.
- HMS – Hospital Medical Software for Cruise Ships: InterData HMS (presumably 'Hospital Medical System') is deployed on cruise ships, notably all ships of the AIDA and TUI Cruises fleets. This is a separate product line generating revenue from cruise line operators.
- TI Hardware and Connectivity Services: Through the DGN TI Starterpaket partnership, InterData bundles TI hardware (Konnektor, card terminals) with its software. While the hardware is sourced from DGN partners (Secunet, Arvato Systems), this creates an ancillary revenue stream from hardware procurement and installation services for new TI connections.

InterData has participated in multiple gematik certification processes and pilot projects: ePA Schnittstelle certification (2021), NFDM Sprint (2016–2017), TI-Feldtest for NFDM and eMP (2020), PTV4 upgrade for ePA (2021). InterData has received gematik confirmation of conformity for all major TI applications.
- KV Telematik GmbHcoreInterData was the first PVS manufacturer to receive KV-Connect certification for all KV-Telematik applications (eArztbrief, DALE-UV, eDialyseDoku, eDMP, eHKS, eKoloskopieDoku) using the DGN GUSbox as the transport layer. KV-Connect is being phased out in October 2025 in favor of KIM.
