Chronic pain syndrome

This code signifies a complex condition characterized by persistent, severe pain that has lasted for an extended period (typically six months or more) and is often accompanied by significant psychological and functional impairment. It represents a chronic pain state where the pain itself becomes the primary problem, often independent of the initial injury or disease.

Use this code when documentation clearly indicates a diagnosis of chronic pain syndrome, emphasizing the multifaceted nature of the patient's pain experience beyond a specific anatomical site or underlying cause. This code is appropriate when the pain is chronic, debilitating, and has led to significant psychosocial impact, such as depression, anxiety, or functional limitations.

• Do not use this code for acute pain or for chronic pain that is clearly attributable to a specific, treatable underlying condition (e.g., chronic low back pain due to disc herniation).
• Always code the underlying cause of the pain first, if known and still present, followed by this code to specify the syndrome.
• Ensure documentation supports the "syndrome" aspect, indicating psychological and/or functional components beyond just chronic pain.
