721.8
ICD-9-CMThis code represents a range of non-specific, less common, or ill-defined conditions affecting the spine that do not fit into more precise diagnostic categories. It encompasses various spinal disorders that are not explicitly classified elsewhere within the ICD-9-CM system, often indicating a broader or less specific diagnosis.
Use this code when documentation indicates a spinal disorder that is not clearly defined as spondylosis, disc disorder, curvature, or other specified spinal conditions. This may include conditions like spinal instability not due to fracture or disc degeneration, or other generalized spinal pain syndromes without a more specific etiology. Supporting documentation should clearly rule out more specific diagnoses.
