Clinical & Coding Specifications
Clinical Context
A typical patient scenario involves an adult presenting with chronic low back pain localized to the lumbar or sacral region. The pain is suspected to originate from the facet (zygapophyseal) joints, often due to conditions such as spondylosis or other specified dorsopathies. After conservative treatments have failed, the provider, typically in an outpatient facility setting (such as an office or hospital outpatient department), performs an image-guided injection of a diagnostic or therapeutic agent into the paravertebral facet joint or the nerves innervating that joint at a single lumbar or sacral level. The procedure is performed by a specialist in pain medicine or interventional pain management, using fluoroscopy or CT guidance to ensure accurate placement of the injection.
