A52.11

What This Code Means

Tabes dorsalis is a late-stage complication of untreated syphilis that damages the nerves in the spinal cord, causing progressive weakness, loss of coordination, and loss of sensation, particularly in the legs. This condition develops years or decades after the initial syphilis infection.

Coding Tips

• •Tabes dorsalis (A52.11) is a manifestation of neurosyphilis and should be coded along with the underlying syphilis diagnosis code when applicable
• •Document the stage and manifestations clearly in the medical record, as this code specifically indicates tertiary syphilis affecting the dorsal columns of the spinal cord
