Workers' compensation
Most employers are required by law to provide workers' compensation insurance through a state system operated by the Department of Labor & Industries. Worker comp pays an employee's medical expenses and provides some income replacement when a worker is injured on the job.

Automobile
If you own and operate commercial vehicles, you should make sure that your fleet is appropriately insured. If business use of a vehicle is minimal and limited to your personal vehicle, the necessary coverage can probably be included in your personal policy. Best bet: Check with your agent to be sure.

Stand-Alone Dental
This plan type provides dental coverage but does not include any other coverage.

Professional liability
Often called “malpractice insurance” or “errors and omissions coverage,” these policies protect professionals such as accountants, lawyers, doctors, dentists, pharmacists, insurance brokers and agents, and consultants, for negligence that injures their clients.

Indemnity
Indemnity plans are also referred to as “fee-for-service.” Unlike managed-care plans, indemnity plans allow absolute freedom in selecting physicians or medical facilities and permit self-referral to a specialist.

Basic Hospital
Basic-hospital plans cover only in-hospital (inpatient) care, not other services. This benefit also may be limited to an approved or network facility. Hospitalization in a different facility may qualify for less coverage or none at all.

Business interruption
If you're unable to run your business due to a covered peril (fire, storm damage, vandalism and so on), business interruption insurance will replace lost income, pay ongoing expenses and pay costs involved in getting you set up in a temporary facility.

Stand-Alone Prescription
This plan type provides prescription-drug coverage, which generally means the insured person can obtain prescription drugs at a set price of a few dollars, but does not include any other coverage.

Fleet coverage
This is multi-vehicle coverage that applies to businesses that rely on a number of vehicles and need to insure them collectively.

Health Maintenance Organization (HMO)
Managed-care insurers — known generally as HMOs — use a primary care physician as a gatekeeper to screen patients and see that appropriate treatment takes place at the lowest level possible. In order to see a specialist or receive specialized care, patients must see the gatekeeper physician first and be referred on.
