2023 UMP Classic (PEBB) Certificate of Coverage 191
• The level of service, supply, intervention, prescription drug, or prescription drug dose is appropriate
considering the potential benefits and harm to the member.
• The level of service, supply, intervention, prescription drug, or prescription drug dose is known to be
effective in improving health outcomes.
• The level of service, supply, intervention, prescription drug, or prescription drug dose recommended for
this condition is cost-effective compared to alternative interventions, including no intervention.
• The service, supply, or intervention is not being recommended for reasons of convenience to the
patient or health care provider.
• For services that the HTCC has reviewed, and that UMP has implemented, medical necessity is
established only when HTCC’s coverage conditions are met.
The fact that a physician or other provider prescribes, orders, recommends, or approves a service or
supply, prescription drug, or prescription drug dose does not make it medically necessary.
The plan may require proof that services, interventions, supplies, or prescription drugs (including court-
ordered care) are medically necessary. Depending on the circumstances, such proof may be
documentation about the member’s condition or scientific evidence about the effectiveness of the
treatment.
The plan will not provide benefits if the required proof is not received, or does not adequately justify the
medical necessity of the service, supply, prescription drug, or prescription drug dose. Claims processing
may be delayed if proof of medical necessity is required but not adequately provided by the health
service provider.
The plan uses scientific evidence from peer-reviewed medical literature to determine effectiveness for
services and interventions not yet in widespread use for the medical condition and member indications
being considered.
For services that the HTCC has reviewed, and that UMP has implemented, state law requires that UMP use
the HTCC’s coverage criteria in determining whether the service is medically necessary. When the HTCC
determines that a service is not covered, then the service is not covered by the plan. If the HTCC
determines that a service is covered, then the HTCC’s criteria (if any) determine medical necessity. The
HTCC’s decisions and related documentation are available on the HCA website at
hca.wa.gov/hta.
For services, interventions, supplies, prescription drugs, or prescription drug doses not related to an HTCC
review, the plan first uses scientific evidence, then professional standards, then expert opinion to
determine coverage.
Scientific evidence consists primarily of controlled clinical trials that either directly or indirectly
demonstrate the effect of the intervention on health outcomes. If controlled clinical trials are not available,
observational studies that demonstrate a causal relationship between the intervention and health
outcomes may be used. Partially controlled observational studies and uncontrolled clinical series may be
suggestive, but do not by themselves demonstrate a causal relationship unless the magnitude of the
effect observed exceeds anything that could be explained either by the natural history of the medical
condition or potential experimental biases.
Interventions for which clinical trials have not been conducted because of epidemiological reasons (that is,
rare or new diseases or orphan populations) shall be evaluated based on professional standards of care or
expert opinion.
A level of service, supply, prescription drug, prescription drug dose, or intervention is considered cost
effective if the benefits and harms relative to the costs represent an economically efficient use of
