California Code, Welfare and Institutions Code - WIC § 14125

(b)(1) In establishing the list of incontinence medical supplies, the department may enter into exclusive or nonexclusive contracts on a bid or negotiated basis with manufacturers, distributors, dispensers, or suppliers of incontinence medical supplies.

(2) To ensure that the health needs of Medi-Cal beneficiaries are met, the department shall, when evaluating a decision to execute a contract, and when evaluating incontinence medical supplies for retention on, addition to, or deletion from, the list of incontinence medical supplies, consider all of the following criteria:

(3) The deficiency of a product when measured by one of the criteria specified in paragraph (2) may be sufficient to support a decision that the product should be deleted from, should not be added to, or should not be retained on, the list of medical supplies. However, the superiority of a product under one criterion may be sufficient to warrant the addition or retention of the product, notwithstanding a deficiency in another criterion.

(4) In the evaluation of the effectiveness of a product, the department may require the manufacturer, distributor, dispenser, or supplier to submit their products to testing by an independent laboratory. For the purposes of this section, “independent laboratory” means an analytical laboratory that is not a subsidiary of, affiliated with, or on retainer for, the manufacturer, distributor, dispenser, or supplier.
