(a) Prior to administration of an agent, a narcotic treatment program shall screen each individual to determine eligibility for admission. The narcotic treatment program shall:

1. (1) Verify that the individual has reached 18 years of age.
2. (2) Verify the individual’s identity, including name, address, date of birth, emergency contact and other identifying data.
3. (3) Obtain a drug use history and current drug use status of the individual.
4. (4) Have a narcotic treatment physician make a face- to-face determination of whether an individual is currently physiologically dependent upon a narcotic drug and has been physiologically dependent for at least 1 year prior to admission for maintenance treatment. The narcotic treatment physician shall document in the patient’s record the basis for the determination of current dependency and evidence of a 1 year history of addiction.

(b) Exceptions to the requirements in subsection (a) are:

1. (1) A 1 year history of physiologic dependency is not required for detoxification or for pregnant patients.
2. (2) Upon readmitting a patient who has been out of a narcotic treatment program for 6 months or less after a voluntary termination, the narcotic treatment program shall update the information in and review the patient’s file to show current opiate narcotic dependency, but need not conduct a physical examination and applicable laboratory tests. Privileges earned during the previous treatment may be reinstated at the discretion of the narcotic treatment physician.

3. (3) A patient who has been treated and later detoxified from comprehensive maintenance treatment may be readmitted to maintenance treatment, without evidence to support findings of current physiologic dependence, up to 2 years after discharge, if the following conditions are met:

   1. (i) The narcotic treatment program attended is able to document prior narcotic drug comprehensive maintenance treatment of 6 months or more.
   2. (ii) The admitting narcotic treatment physician, exercising reasonable clinical judgment, finds readmission to comprehensive maintenance treatment to be medically justified.
