(1) A health carrier that imposes different prior authorization standards and criteria for a covered service among tiers of contracting providers of the same licensed profession in the same health plan shall inform an enrollee which tier an individual provider or group of providers is in by posting the information on its web site in a manner accessible to both enrollees and providers.

No carrier may deny or limit coverage for such initial six visits on the basis of medical necessity or appropriateness if the patient's treating provider has determined that such visits are medically necessary. Notwithstanding RCW 48.43.515(5) this section may not be interpreted to limit the ability of a health plan to require a referral or prescription for the therapies listed in this section.

(5) A health carrier may not require a provider to provide a discount from usual and customary rates for health care services not covered under a health plan, policy, or other agreement, to which the provider is a party.
