Knee Arthroscopy

Coverage decision

Knee arthroscopy using debridement and lavage as a treatment for osteoarthritis of the knee is not covered.

This does not apply to the use of knee arthroscopy for diagnostic purposes.

L&I’s medical treatment guidelines for knee surgery are available at: http://www.Lni.wa.gov/ClaimsIns/Files/OMD/MedTreat/KneeSurgery.pdf

Background Policy Information

The State Health Technology Clinical Committee (HTCC) reviewed knee arthroscopy using debridement and lavage for the treatment of osteoarthritis on August 15, 2008. Based on a systematic review of the evidence of safety, efficacy and cost-effectiveness, the committee’s determination is that knee arthroscopy with debridement and lavage is not covered for patients where the only indication is osteoarthritis.
