Spond in diseases classd elswhr, multiple sites in spine

This code signifies a spinal disorder, not primarily originating in the spine itself, that affects multiple segments of the vertebral column. It indicates a secondary manifestation of an underlying systemic disease or condition impacting the spine.

Apply this code when documentation specifies spondylopathy affecting multiple spinal regions (e.g., cervical and lumbar, or thoracic and sacral) due to an underlying disease classified elsewhere. This is appropriate when the primary condition is known and coded separately, and the spinal involvement is a complication or manifestation of that disease.

• Always sequence the underlying systemic disease first, as this code is for a manifestation classified elsewhere.
• Ensure documentation explicitly states "multiple sites" or lists specific affected spinal regions to justify its use over single-site codes.
• Avoid using this code if the spondylopathy is primary to the spine; instead, refer to codes within the M45-M48 series.
