Aggregate lifetime limit means a dollar limitation on the total amount of specified benefits that may be paid under a health plan (or health insurance coverage offered in connection with a plan) for any coverage unit.

Annual dollar limit means a dollar limitation on the total amount of specified benefits that may be paid in a twelve-month period under a health plan (or health insurance coverage offered in connection with a plan) for any coverage unit.

Approved treatment program means a discrete program of chemical dependency treatment provided by a treatment program certified by the department of social and health services as meeting standards adopted under chapter 70.96A RCW.

Chemical dependency professional means a person certified as a chemical dependency professional by the Washington state department of health under chapter 18.205 RCW.

Classification of benefits means a group into which all medical/surgical benefits and mental health or substance use disorder benefits offered by a health plan must fall. For the purposes of this rule, the only classifications that may be used are: Inpatient, in-network; inpatient, out-of-network; outpatient, in-network; outpatient, out-of-network; emergency care; and prescription drugs.

Coverage unit means the way in which a health plan or issuer groups individuals for purposes of determining benefits, or premiums or contributions. For example, different coverage units include self-only, family, and employee-plus-spouse.

Cumulative financial requirements means financial requirements that determine whether or to what extent benefits are provided based on accumulated amounts and include deductibles and out-of-pocket maximums. Financial requirements do not include aggregate lifetime or annual dollar limits.

Cumulative quantitative treatment limitations means treatment limitations that determine whether or to what extent benefits are provided based on accumulated amounts, such as annual or lifetime day or visit limits.

Emergency condition, for the purpose of this subchapter, means a condition manifesting itself by acute symptoms of sufficient severity, including severe emotional or physical distress or a combination of severe emotional and physical distress, that a prudent layperson, who possesses an average knowledge of health and medicine, could reasonably expect the absence of immediate medical or mental health attention to result in a condition placing the health of the individual, or with respect to a pregnant woman, the health of the woman or her unborn child, in serious jeopardy.

Essential health benefits (EHBs). EHBs have the same definition as found in WAC 284-43-5600 or 284-43-5602, as appropriate. The definition of EHBs includes mental health and substance use disorder services, including behavioral health treatment. For EHBs, including mental health and substance use disorder benefits, federal and state law prohibit limitations or age, condition, lifetime and annual dollar amounts.

Financial requirements means cost sharing measures such as deductibles, copayments, coinsurance, and out-of-pocket maximums. Financial requirements do not include aggregate lifetime or annual dollar limits.

Health carrier or issuer has the same meaning as RCW 48.43.005(25).

Health plan has the same meaning as RCW 48.43.005(26).

Medical/surgical benefits means benefits with respect to items or services for medical conditions or surgical procedures, as defined under the terms of the plan or health insurance coverage and in accordance with applicable federal and state law, but does not include mental health or substance use disorder benefits. Any condition defined by the plan or coverage as being or as not being a medical/surgical condition must be defined to be consistent with generally recognized independent standards of current medical practice (for example, the most current version of the International Classification of Diseases (ICD) or state guidelines).

(a) With regard to chemical dependency and substance use disorder is defined by the most recent version of The ASAM Criteria, Treatment Criteria for Addictive, Substance Related, and Co-Occurring Conditions as published by the American Society of Addiction Medicine (ASAM).

(b) With regard to mental health services, pharmacy services, and any substance use disorder benefits not governed by ASAM, is a carrier determination as to whether a health service is a covered benefit because the service is consistent with generally recognized standards within a relevant health profession.

Mental health benefits means benefits with respect to items or services for mental health conditions, as defined under the terms of the plan or health insurance coverage and in accordance with applicable federal and state law. Any condition defined by the plan or coverage as being or as not being a mental health condition must be defined to be consistent with generally recognized independent standards of current medical practice (for example, the most current version of the Diagnostic and Statistical Manual of Mental Disorders (DSM), the most current version of the International Classification of Diseases (ICD), or state guidelines.

Nonquantitative treatment limitations (NQTL) means processes, strategies, or evidentiary standards, or other factors that are not expressed numerically, but otherwise limit the scope or duration of benefits for treatment. NQTLs include, but are not limited to:

(a) Medical management standards limiting or excluding benefits based on medical necessity or medical appropriateness, or based on whether the treatment is experimental or investigative;

(b) Formulary design for prescription drugs;

(c) For plans with multiple network tiers (such as preferred providers and participating providers), network tier design;

(d) Standards for provider admission to participate in a network, including reimbursement rates;

(e) Plan methods for determining usual, customary, and reasonable charges;

(f) Refusal to pay for higher-cost therapies until it can be shown that a lower-cost therapy is not effective (also known as fail-first policies or step therapy protocols);

(g) Exclusions based on failure to complete a course of treatment; and

(h) Restrictions based on geographic location, facility type, provider specialty, and other criteria that limit the scope or duration of benefits for services provided under the plan or coverage.

Predominant level: If a type of financial requirement or quantitative treatment limitation applies to substantially all medical surgical benefits in a classification, the predominant level is the level that applies to more than one-half of the medical/surgical benefits in that classification subject to the financial requirement or quantitative treatment limitation.

Quantitative parity analysis means a mathematical test by which plans and issuers determine what level of a financial requirement or quantitative treatment limitation, if any, is the most restrictive level that could be imposed on mental health or substance use disorder benefits within a classification.

Quantitative treatment limitations means types of objectively quantifiable treatment limitations such as frequency of treatments, number of visits, days of coverage, days in a waiting period or other similar limits on the scope or duration of treatment.

Substance use disorder includes illness characterized by a physiological or psychological dependency, or both, on a controlled substance regulated under chapter 69.50 RCW and/or alcoholic beverages. It is further characterized by a frequent or intense pattern of pathological use to the extent the user exhibits a loss of self-control over the amount and circumstances of use; develops symptoms of tolerance or physiological and/or psychological withdrawal if use of the controlled substance or alcoholic beverage is reduced or discontinued; and the user's health is substantially impaired or endangered or his or her social or economic function is substantially disrupted. Any disorder defined by the plan as being or as not being a substance use disorder must be defined to be consistent with generally recognized independent standards of current medical practice (for example, the most current version of the DSM, the most current version of the ICD, or state guidelines).

Substance use disorder benefits means benefits with respect to items or services for substance use disorders, as defined under the terms of the plan or health insurance coverage and in accordance with applicable federal and state law. Substance use disorder benefits must include payment for reasonable charges for medically necessary treatment and supporting service rendered to an enrollee either within an approved treatment program or by a health care professional that meets the requirements of RCW 18.205.040(2), as part of the approved treatment plan.

Substantially all: A type of financial requirement or quantitative treatment limitation considered to apply to substantially all medical/surgical benefits in a classification of benefits if it applies to at least two-thirds of all medical/surgical benefits in that classification as determined by WAC 284-43-7040 (2)(a).

Treatment limitations means limits on benefits based on the frequency of treatment, number of visits, days of coverage, days in a waiting period, or other similar limits on the scope or duration of treatment. Treatment limitations include both quantitative treatment limitations, which are expressed numerically (such as fifty outpatient visits per year), and nonquantitative treatment limitations, which otherwise limit the scope or duration of benefits for treatment under a plan or coverage. A permanent exclusion of all benefits for a particular condition or disorder, however, is not a treatment limitation for purposes of this section.
