(b) Meet the requirements of WAC ((388-550-2301)) 182-550-2301.

(4) The ((department)) agency authorizes payment for bariatric surgery and bariatric surgery-related services in three stages:

(a) Stage one(( -- )) - Initial assessment of client;

(c) Stage three(( -- )) - Bariatric surgery.

Stage one(( -- )) - Initial assessment

(5) Any ((department-enrolled)) agency-enrolled provider who is licensed to practice medicine in the state of Washington may examine a client requesting bariatric surgery to ascertain if the client meets the criteria listed in subsection (6) of this section.

(6) The client meets the preliminary conditions of stage one when:

(a) The client is ((between)):

(i) Twenty-one ((and)) through fifty-nine years of age; or

(ii) Eighteen through twenty years old for laparoscopic adjustable gastric banding (LAGB) only;

(b) The client has a body mass index (BMI) of thirty-five or greater;

The client or the client's provider must reapply for prior authorization from the ((department)) agency to restart stage two. For the purpose of this section, "initial body weight" means the client's weight at the first evaluation appointment.

(10) If the client fails to complete all of the requirements of subsection (9) of this section, the ((department)) agency will not authorize stage three(( -- )) - Bariatric surgery.

(11) If the client is unable to meet all of the stage two criteria, the client or the client's provider must reapply for prior authorization from the ((department)) agency to reenter stage two.
