Lumbago

This code represents non-specific low back pain, often characterized by aching, stiffness, or discomfort in the lumbar region. It is a general term for pain in the lower back that does not radiate to the legs and is not attributable to a specific nerve root compression or other definitive pathology.

Use this code when documentation indicates generalized low back pain without further specification of cause or radiating symptoms. It is appropriate for initial evaluations of acute or chronic lumbago where a more precise diagnosis is not yet established or is ruled out. Documentation should clearly state "lumbago" or "low back pain" without evidence of sciatica or other neurological involvement.

• Do not use if the pain radiates to the leg; consider codes for sciatica or radiculopathy.
• Avoid using this code if a more specific diagnosis, such as disc herniation or spinal stenosis, is documented.
• This is a symptom code; if an underlying cause is identified, code the definitive diagnosis first, followed by this code if applicable.
