See Investigational Procedures.

Any health care goods or services that a health plan determines are not generally accepted by U.S. health care professionals as effective for treating the condition or illness for which their use is proposed. Generally, these are denied for coverage because there is a lack of scientific evidence supporting their effectiveness and/or safety.

Also called investigational or unproved procedures, this covers all health care services, supplies, treatments, or drug therapies that have been determined by the health plan to not be generally accepted by health care professionals as effective in treating the illness for which their use is proposed. Experimental procedures are said to not be proven scientifically to effectively treat the condition for which their use is prescribed.
