Transformation in Health Insurance: Shifting from Private Health Insurance to Complementary Health Insurance
From PHI to CHI: shifting needs, cost dynamics and the priorities shaping the future of the health insurance market.

Health insurance has undergone a significant transformation over time. It has evolved beyond being a product that merely provides financial protection against healthcare expenses and has become a strategic value proposition that supports quality of life for individuals and institutions alike.
The Journey of Health Insurance from the 2000s to Today
In the 2000s, Private Health Insurance (PHI) primarily stood out as a product preferred by individuals and institutions seeking access to extensive hospital networks, high coverage limits and comprehensive healthcare services.
As private hospital investments increased, access to healthcare services became easier and employee benefits gained greater importance, corporate health insurance assumed a central role in companies' employee engagement and retention policies.
In recent years, however, the health insurance market has entered a new phase of transformation, with Complementary Health Insurance (CHI) becoming a product accessible to much broader segments of the population.
PHI and CHI: Two Different Solutions for Two Different Needs
Today, health insurance is largely structured around two core product models:
- Private Health Insurance (PHI): PHI is generally preferred by individuals and institutions with higher coverage expectations, offering broader hospital networks, higher policy limits and more customizable coverage options.
- Complementary Health Insurance (CHI): CHI provides supplementary coverage for services within the scope of the Social Security Institution (SGK) at SGK-contracted private hospitals, enabling insured individuals to access private healthcare services at more affordable costs.
The rapid growth of CHI in health insurance portfolios has become particularly notable in recent years. Based on the number of insured individuals, CHI has reached an estimated share of approximately 65-70%, while PHI accounts for around 30-35%. From a premium-production perspective, however, a different distribution may emerge due to the broader and higher-limit coverage structure of PHI. Data from the first period of 2025 indicate that PHI premium production was higher than that of CHI.
Changing Cost Structures and a New Approach
Changes in healthcare costs are leading institutions to assess their health insurance plans more strategically. In particular, physician fees, hospital costs and healthcare utilization patterns require more careful analysis in policy design.
The approximately 20% periodic increase announced in the Turkish Medical Association's (TTB) second-half 2026 coefficients for private medical practice, together with an annual increase reaching approximately 40%, represents an important indicator of the changing healthcare cost environment.
For this reason, institutions are no longer focused solely on the premium level of a policy. They are increasingly prioritizing the right coverage structure, utilization analysis and sustainable healthcare solutions.
The Future of Health Insurance
In the period ahead, personalized products, preventive healthcare services, digital health applications and flexible models designed around employee needs will gain further importance in health insurance.
Success in health insurance is not simply about finding the lowest-cost policy. It depends on accurately analyzing the needs of both employees and institutions and developing solutions that create long-term value.
Today's health insurance approach is not limited to facilitating access to treatment. It represents a strategic investment model that supports healthy living, strengthens employee engagement and creates sustainable benefits for institutions.
