## **What is the HCPCS code J7323 for?** The HCPCS code J7323 is one of many J codes, which are codes mostly meant to designate injected medications/drugs. In the case of J7323, what's being injected is hylarunon or a derivative, euflexxa, specifically per dose. This injection is administered intra-articularly. Unlike other dose codes, this doesn't specify a specific amount per dose. The purpose of this injection is to be used on patients diagnosed with osteoarthritis of the knee. It provides knee pain relief by supplementing the natural hyaluronic acid in the affected knee, and it improves lubrication and cushioning. This will lead to improved joint function (relative to how badly impacted the knee is) and improved mobility. Healthcare providers will inject this into the knee joint space. This intra-articular hyaluronic acid injection is only viable if conservative treatments for osteoarthritis of the knee have failed, such as physical therapy and taking NSAIDs.

## **Documentation requirements for J7323** As with any procedure, especially involving injecting drugs into patients, it's important to document the following before you file for a claim that includes this code: - The full name of the personnel who administered the injection + their credentials - The name and address of the facility where the injection was administered, including the drug code - The full name of the patient - The date and time of the drug administration by injection - Patient records showing they have been diagnosed with knee osteoarthritis (and other types like unilateral secondary osteoarthritis, or bilateral secondary osteoarthritis), and assessments of their joint health and function to support medical necessity - There should be documentation showing that conservative treatments have not worked - Treatment plans currently being followed by the patient - The exact dosages and the specific knee it was injected into
