Overlake Hospital Association v. Department of Health

Summary

The Washington Supreme Court reviewed the Department of Health’s methodology for determining the need for an additional ambulatory surgical facility under the certificate-of-need program. The court held that the governing regulation was ambiguous and deferred to the Department’s interpretation, which excluded exempt facilities from existing-capacity calculations but included surgeries performed there in projected future need. The court reversed the Court of Appeals and affirmed issuance of the certificate of need to Swedish Health Services.

Holdings

1. WAC 246-310-270(9) is ambiguous, and it permits the Department to exclude exempt facilities from existing operating-room capacity while including surgeries performed in those facilities when projecting future need.
2. The Department's decision to issue Swedish a certificate of need was not arbitrary or capricious.

Questions Presented

1. Whether WAC 246-310-270(9) permits the Department of Health to exclude exempt physician- and dentist-office surgical facilities from existing capacity while including surgeries performed in those facilities in projected future need.
2. Whether the Department's methodology was arbitrary and capricious or otherwise erroneous under the certificate-of-need statutes and regulations.
3. What level of deference the court should give the Department's interpretation of the ambiguous regulation.

Disposition
