Medical necessity for this procedure is established by the presence of significant synovial inflammation or damage causing chronic pain and/or functional limitations unresponsive to conservative management.Documentation should demonstrate a clear correlation between the patient's symptoms and the need for surgical intervention.

The orthopedic surgeon or qualified healthcare professional performs the arthrotomy and synovectomy, ensuring proper hemostasis and closure of the joint capsule. Preoperative preparation, anesthesia administration, and postoperative care are typically handled by appropriate members of the surgical team.

IMPORTANT If only anterior OR posterior arthrotomy with synovectomy is performed, use CPT code 27334.

In simple words: The doctor makes a cut in the knee joint to remove damaged tissue lining the joint (synovium) from the front, back, and behind the knee. This helps reduce pain and improve movement.

This procedure involves a surgical incision (arthrotomy) into the knee joint, followed by the excision of the torn or damaged synovium (synovectomy) in both the anterior and posterior regions, extending to include the popliteal area.The goal is to alleviate pain and improve the patient's gait.The procedure includes meticulous hemostasis and layered closure of the joint capsule.

Example 1: A patient presents with chronic knee pain and limited range of motion due to significant synovitis.Arthrotomy and synovectomy are performed to remove the inflamed synovium, alleviating pain and improving joint mobility., A patient with rheumatoid arthritis experiences severe knee pain and swelling from significant synovial inflammation.This procedure is undertaken to address the inflammation and improve joint function., Following a knee injury, a patient experiences persistent pain and swelling from post-traumatic synovitis.This procedure is utilized to remove the inflamed tissue and address persistent symptoms.

* Preoperative diagnosis and imaging (X-rays, MRI) documenting synovial inflammation or damage.* Operative report detailing the extent of synovectomy (anterior, posterior, popliteal).* Postoperative assessment including pain scores, range of motion, and any complications.

** This code encompasses both diagnostic and therapeutic aspects.The extent of synovectomy is crucial for accurate coding.Any significant complications or unexpected findings should be documented.
