Client
DAK-Gesundheit is not only one of the five largest statutory health insurance companies in Germany — it is also a company steeped in tradition. DAK-Gesundheit is a self-governing public corporation. It is subject to the principle of solidarity and has 5.5 million insured members and around 300 offices nationwide.
Challenge
DAK Gesundheit already offers its members many digital services via its app and website, such as submitting documents, filing applications, secure communication, barrier-free use, collecting bonus points, and contacting the company via chat and telephone.
The goal is to continuously expand this offering in order to remain attractive, especially to digitally savvy customers. Growing user numbers and digital topics place high demands on security, stable systems, and well-designed processes. A key challenge is to design internal processes efficiently (e.g., through dark processing) while simultaneously developing new digital offerings for insured persons — both of which must be balanced.
Objective
The focus is on the further development of digital health services – for example, new e-prescriptions such as DIGA, eAU, or Digitalpost. The e-prescription for medical aids is also being redeveloped in the “eGesundheit Deutschland” project.
This includes improving the digital mailbox for insured persons, introducing digital registrations in selective contracts, and connecting existing systems such as 21c|ng via BitGo and GeCo.
The technical implementation comprises modern backend development, the use of Spring Boot microservices (Java 17), and the development of new REST interfaces according to the API-first principle with OpenAPI 3. Security is a high priority – based on the OWASP Top 10 standards.
The goal is to make digital processes in healthcare secure, user-friendly, and future-proof.
Solution and benefits
The optimization of backend systems ensures smooth processes and compliance with technical requirements. Innovative e-health solutions strengthen competitiveness and increase attractiveness for insured persons.
The legally compliant implementation of new digital offerings creates trust and improves service. A modern digital mailbox enables secure and efficient communication of sensitive health data.
Simplified digital processes — such as when registering for selective contracts — reduce administrative effort. A high level of protection safeguards against data misuse. Carefully developed microservices and interfaces ensure reliability, quality, and customer satisfaction.
Client: DAK
Project name: Backend development for the DAK app
Challenge
With the DAK app and website, DAK Gesundheit already offers its members many exciting and useful ways to manage their health insurance needs digitally.
- Simply scan and submit documents (e.g., invoices)
- Request certificates and submit applications
- Securely access messages from DAK-Gesundheit
- Use the app barrier-free (e.g., through a high-contrast appearance)
- Collect bonus points and apply for subsidies
- Contact DAK-Gesundheit via chat, telephone, and contact form, or find the nearest service center
The goal is to further expand these offerings for insured persons in order to remain and become even more attractive on the market, especially for customers interested in digital services.
With the increasing number of e-topics and users, security, stable and error-free software, scalable systems, and cleanly designed processes play a particularly important role here.
Care must always be taken to strike a balance between improving internal processes (e.g., with dark processing) and new topics for end customers.
