REVIEWED AND UPDATED: December 2025

L&I’s Office of the Medical Director has determined that the HTCC’s determination about continuous glucose monitoring (CGM) does not apply to Washington’s workers’ compensation because diabetes is not typically work related, and therefore does not meet the definition of an industrial injury or occupational disease.

In rare situations, L&I may pay for CGM based on the criteria set forth in the 2025 HTCC’s determination on CGM if diabetes is an accepted condition on the claim. It must be documented in the claim file that the industrial injury giving rise to the claim was a proximate cause of the diabetic condition or how diabetes is related to the claim.

Background Information

Continuous glucose monitoring was re-reviewed by the State Health Technology Clinical Committee (HTCC) in 2018 and 2025. Complete information on this HTCC determination is available at:  https://www.hca.wa.gov/about-hca/health-technology-assessment/health-technology-reviews.
