Chronic pain syndrome

This code represents a complex, persistent pain condition that has lasted for an extended period, typically six months or longer, and is often associated with significant psychological and social impairment. It describes a syndrome where pain is the primary problem, rather than a symptom of an underlying acute injury or disease.

Use this code when documentation clearly indicates a diagnosis of chronic pain syndrome, often after extensive workup has failed to identify a specific treatable underlying cause for the persistent pain. This code is appropriate when the pain has become a disease entity in itself, impacting daily functioning and quality of life.

• Do not use this code for acute pain or for chronic pain where a more specific underlying cause (e.g., chronic low back pain due to disc degeneration) can be coded.
• Always sequence this code after any definitive underlying conditions that are being treated or managed, if applicable.
• Ensure documentation supports the "syndrome" aspect, indicating widespread or complex chronic pain, rather than localized chronic pain.
