2025 ICD-10-CM code G89.2

Chronic pain, not elsewhere classified.

Do not use this code if a more specific pain code applies. Do not report this code as the primary diagnosis if the underlying condition causing the pain is known and is being treated.

Medical necessity is established when the chronic pain significantly impacts the patient's function and quality of life. The documentation should clearly demonstrate the severity and chronicity of the pain, the failure of other treatments, and the need for ongoing pain management.

Clinicians diagnose chronic pain based on patient history (medical, surgical, or trauma-related), signs, symptoms, and physical examination. Diagnostic tests such as blood work, X-rays, CT scans, and ultrasounds are used to determine the cause and severity of the pain. Treatment is usually symptomatic, potentially including NSAIDs, muscle relaxants, anxiolytics, antidepressants, physical therapy, biofeedback, and other non-pharmacological treatments.

In simple words: This code represents long-lasting pain that continues even after an injury, disease, or surgery has healed. This pain can last for months or even years and is difficult to treat. It's important to note that this code is used when the pain cannot be classified under a more specific diagnosis.

Chronic pain that is not otherwise specified in the ICD-10-CM.

Example 1: A patient experiences persistent lower back pain for over a year after a fall, with no other identifiable cause. Imaging studies reveal no ongoing injury or structural abnormalities., A patient has widespread muscle pain and fatigue for several months, and various tests have ruled out other medical conditions. The pain significantly impacts their daily life and mental well-being., A patient reports constant headaches that have persisted for several years, despite trying various treatments and medications. No specific cause for the headaches has been found through neurological examinations or imaging.

Documentation should include the type, location, and duration of pain, along with details about the causative factors if known. Medical history, physical exam findings, and results of any diagnostic testing should also be included. It is crucial to document the impact of pain on the patient's daily activities and any psychological effects.

** This code excludes conditions such as causalgia, central pain syndrome, chronic pain syndrome, complex regional pain syndrome, neoplasm-related pain, reflex sympathetic dystrophy, generalized pain NOS, and pain disorders exclusively related to psychological factors.
