(c) In addition to the mental health benefits established pursuant to this section, any such policy shall also provide benefits on a non-discriminatory basis for children and adolescents under the age of 19 for the diagnosis and treatment of non-biologically-based mental, behavioral or emotional disorders, as described in the most recent edition of the DSM, which substantially interfere with or substantially limit the functioning and social interactions of such a child or adolescent; provided, that said interference or limitation is documented by and the referral for said diagnosis and treatment is made by the primary care provider, primary pediatrician or a licensed mental health professional of such a child or adolescent or is evidenced by conduct, including, but not limited to: (1) an inability to attend school as a result of such a disorder, (2) the need to hospitalize the child or adolescent as a result of such a disorder, or (3) a pattern of conduct or behavior caused by such a disorder which poses a serious danger to self or others. The insurer shall continue to provide such benefits to any adolescent who is engaged in an ongoing course of treatment beyond the adolescent's nineteenth birthday until said course of treatment, as specified in said adolescent's treatment plan, is completed and while the benefit contract under which such benefits first became available remains in effect, or subject to a subsequent benefits contract which is in effect.

(d) Any such policy shall be deemed to be providing such benefits on a nondiscriminatory basis if the policy does not contain any annual or lifetime dollar or unit of service limitation on coverage for the diagnosis and treatment of said mental disorders which is less than any annual or lifetime dollar or unit of service limitation imposed on coverage for the diagnosis and treatment of physical conditions.

(e) Any such policy shall also provide medically necessary benefits for the diagnosis and treatment of all other mental disorders not otherwise provided for in this section and which are described in the most recent edition of DSM during each 12 month period for a minimum of 60 days of inpatient treatment and for a minimum of 24 outpatient visits.

Only licensed mental health professionals shall be allowed to deny services mandated by this section. The provisions of this subsection shall not be construed as applying to denials of service resulting from an insured's lack of insurance coverage or the use of a facility or professional which, if applicable under the insured's benefits contract, has not entered into a negotiated agreement with the insurer. The benefits provided in any policy pursuant to this section shall meet all other terms and conditions of the policy not inconsistent with this section.
