Clarifies the authority of physician assistants to sign and attest to documents.

Finds that some state agencies and departments do not accept the signature of physician assistants on certain certificates, reports, and other documents that their supervising physician is permitted to sign, notwithstanding the fact that the signing of such documents is within the physician assistant's scope of practice, covered under their practice arrangement plan, and permitted pursuant to WAC 246-918-140.

Declares an intent to clarify in statute what was adopted by rule in WAC 246-918-140, that a physician assistant may sign and attest to any document that might ordinarily be signed by the supervising physician and that is consistent with the terms of the practice arrangement plan.
