What type of plan is Ken most likely enrolled in based on his employer's benefits?

The Basic Surgical Expense Plan is a limited type of health insurance coverage that provides benefits specifically for surgical procedures. This plan covers a range of surgical expenses but does not typically cover hospital stays, routine doctor visits, or other medical services outside of surgery. Employers who offer a Basic Surgical Expense Plan are likely prioritizing cost control for surgical procedures, as it's a more basic, less comprehensive health insurance option.

In contrast to this, a Point of Service Plan combines elements of both HMO and PPO plans, offering flexibility with higher costs when using out-of-network services, which isn't aligned with Ken's situation if he's specifically covered under a surgical plan. A PPO Plan offers more flexibility and a wider network but would not be categorized as a Basic Surgical Expense Plan, which is more limited in scope. An HMO Plan requires members to select a primary care physician and generally covers more comprehensive healthcare services than just surgical expenses.

Therefore, based on the context provided, Ken is most likely enrolled in the Basic Surgical Expense Plan, as it directly addresses surgical needs with specified limits rather than the broader coverage offered by other types of health insurance plans.
