Affordability and cost concerns
However, health insurance costs across the industry have been rising faster than inflation for years, and UnitedHealthcare is no exception. The average health insurance premium for families in 2024 was $25,572 per year, while single workers paid an average of $8,951. UnitedHealthcare's premiums can be on the high side, so it is important to compare costs when shopping for a plan.
UnitedHealthcare offers a range of individual and family plan options, including ACA Marketplace plans, Medicare, Medicaid, short-term, and dental plans, as well as employer-sponsored plans.

However, UnitedHealthcare has received criticism for its customer service and denial of coverage. Some customers have reported difficulties in finding a primary care doctor who accepts their plan, and the company has been accused of denying coverage for necessary medical procedures.
