Hyaluronic Acid/Viscosupplementation

Hyaluronic acid is a naturally occurring component of synovial fluid and cartilage within our joints. Its viscous nature is thought to act as a lubricant, with its elasticity acting as a shock absorber. In patients with osteoarthritic joints, most commonly the knee(s), the availability of this substance is reduced, making them more susceptible to damage. Viscosupplementation is the act of injecting hyaluronic acid or hyaluronan as a means of treating osteoarthritic joints. These products have several brand names. This updated coverage decision adds new brand names that are currently on the market.

Coverage decision: Covered with conditions (Effective date: June 1, 2014; last updated*: February 2019).
