California Code, Welfare and Institutions Code - WIC § 14088.25

(a) The department may conduct onsite reviews of a provider or facility that has agreed with the primary care case management contractor or a potential contractor to provide services to beneficiaries enrolled with the contractor. These reviews may be for purposes such as evaluating the capabilities of potential contractors, monitoring quality of care, investigating complaints, and ensuring contractor compliance with the terms of the contract entered into pursuant to this article.

(b) Prior to adding a provider or facility to an existing network of providers and facilities, the primary care case management contractor shall submit a complete prequalification package to the department. The department shall provide to the contractor written acknowledgment that the package is complete within 10 working days.

(e) In the conduct of the onsite review of the provider or facility, the department shall not condition approval of the site on adherence by the provider or facility to requirements that are not contained in any statute, regulation, or commonly accepted community standard of medical practice that directly applies to the category of provider or facility being inspected. This subdivision does not, however, relieve the contractor of any obligations under the contract entered into pursuant to this article.
