Posterior cord syndrome

This code identifies a neurological condition characterized by damage to the posterior columns of the spinal cord. This damage typically results in impaired proprioception, vibratory sensation, and fine touch below the level of the lesion, while motor function, pain, and temperature sensation remain relatively intact.

Assign this code when documentation explicitly states a diagnosis of posterior cord syndrome. This diagnosis is often supported by neurological examination findings consistent with dorsal column deficits, such as a positive Romberg sign, impaired joint position sense, and diminished vibratory perception.

• Differentiate from other spinal cord syndromes (e.g., anterior cord, central cord) based on the specific neurological deficits documented.
• Always code an underlying cause if known and documented (e.g., vitamin B12 deficiency, tabes dorsalis, spinal cord tumor).
• Ensure the documentation clearly specifies "posterior cord syndrome" rather than a general spinal cord injury or myelopathy.
