Myelopathy in diseases classified elsewhere

This code signifies myelopathy, which is a neurological deficit due to spinal cord compression or injury, when it arises as a manifestation of an underlying systemic disease or condition. It indicates that the spinal cord dysfunction is secondary to a primary illness affecting other body systems, rather than a direct spinal structural issue.

Use this code when documentation clearly links myelopathy to a systemic disease, such as a metabolic disorder, infectious disease, or autoimmune condition. Examples include myelopathy associated with multiple sclerosis, sarcoidosis, or vitamin B12 deficiency. The physician's notes should explicitly state the underlying disease causing the myelopathy.

• Always code the underlying systemic disease first, followed by this code to indicate the myelopathy as a manifestation.
• Carefully review documentation to ensure the myelopathy is indeed secondary to a classified elsewhere disease and not due to intervertebral disc disease or spondylosis, which are excluded.
• Avoid using this code if the myelopathy is directly attributed to a spinal structural issue; refer to the Excludes1 notes for appropriate alternatives.
