WELLESLEY, Mass., May 21, 2026 /PRNewswire/ -- Sun Life U.S. has released its annual High-Cost Claims and Injectable Drug Trends report, which analyzed over 70,000 high-dollar medical claims from more than 3,300 self-funded employers across the country. This year's report shows that secondary (comorbid) conditions, long inpatient hospitalizations and injectable drugs are the biggest drivers of claims above $3 million. Other contributing factors include conditions existing from birth (congenital anomalies), complicated surgeries and gene therapies.
Sun Life spotlights the costliest medical conditions and injectable drugs driving million-dollar medical claims
Some of the most common conditions resulting in claims above $3 million include orthopedic/musculoskeletal (MSK) conditions, newborn/infant care (premature birth) and cancer. While cancer and premature births have been top drivers of million-dollar and multimillion-dollar claims for several years, orthopedic/MSK conditions have only recently reached this level, suggesting increases in severity as well as developments in therapies and treatments. Orthopedic/MSK conditions and cancer are also two of the most frequent diagnoses for short-term disability claims.
"We have a real opportunity to help people achieve meaningful, improved health outcomes by prioritizing whole-person care," said Jennifer Collier, president, Health and Risk Solutions, Sun Life U.S. "Several of these high-cost health conditions occur as comorbidities, such as orthopedic/MSK and cancer. We tend to think about diagnoses and treatments individually, but care is more effective when we recognize the interconnectedness of health conditions. By getting people the right care, we can improve both health and cost outcomes, benefitting both members and employers."
Comorbidities have long been a major contributor to high-cost and multimillion-dollar claims. Multiple conditions can complicate treatment plans, exacerbate the primary diagnosis and prolong recovery. Sun Life's claims data analysis in the report identifies strong connections among cancer, cardiovascular and chronic kidney diseases, and orthopedic/MSK conditions. These conditions share several risk factors, including age, obesity, diabetes and inflammation.
Rising cost of care
Healthcare costs continue to increase as specialty treatments and gene therapies become more prevalent. Supporting these life-saving treatments is crucial, as Sun Life continues to explore ways to improve outcomes and manage risk.
- Million-dollar+ claims increased in frequency by 46% from 2022 - 2026.
- Spending on treating liver disease grew 43% in 2025 from the previous year, with an average cost per patient of $230,000.
- The most expensive drug treatment, at an average cost of $3.6 million, was Elevidys, a gene therapy that slows the progression of Duchenne muscular dystrophy.
- The highest multimillion-dollar claims were for blood cancers (leukemia/lymphoma/myeloma), with an average of $5.45 million in 2025; the highest claim for a single leukemia patient in 2025 was nearly $8 million.
Impact of GLP-1s
Many high-dollar conditions are associated with obesity and diabetes. Employers have an opportunity to broaden coverage of GLP-1s and proactively reduce the risk of major health conditions that can result in high-dollar claims.
- While the cost of GLP-1s per person is still relatively low, high-dollar claims that include GLP-1s increased by 24% over the past year.
- GLP-1s have broader patient eligibility than many of the higher-cost specialty drugs in Sun Life's report, and can significantly reduce the risk of costlier conditions associated with obesity.
- Several of the highest-cost conditions (kidney disease, cardiovascular disease and orthopedic/MSK conditions), are often associated with obesity and related health issues.
Why health services matter
Programs that provide health support services can have substantial impact on health outcomes and reduce medical costs, particularly if they target the more frequently seen conditions like cancer and MSK - also both common conditions for disability leave.
- Osteoarthritis (OA), a common MSK condition, is more prevalent (54%) in patients on dialysis for chronic kidney disease (CKD). Research cited in the report suggests that OA may even be considered a predictor for CKD.
- The most prevalent and frequent diagnosis among people aged 20-59 (i.e. those in the workforce) were solid cancers (malignant neoplasm).
