ICD-10 Code A52.11 – Tabes dorsalis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A52.11 – Tabes dorsalis
What it is
Use this code for tabes dorsalis, a late neurologic manifestation of syphilis that affects the spinal cord. It is a distinct diagnosis, not a general syphilis code.
Clinical signs
Typical findings include sensory ataxia, lightning pains, loss of position sense, and absent deep tendon reflexes. Clinical features vary; refer to documentation.
When to use this code
Assign A52.11 when the provider documents tabes dorsalis or confirms late neurosyphilis with dorsal column involvement. Use it for cases described as syphilitic myelopathy or classic tabetic neurologic disease. Code additional manifestations or the underlying syphilis stage when documented.
Do not use for
Do not use this code for uncomplicated syphilis, nonspecific neuropathy, or other neurologic disorders without documentation of tabes dorsalis. Check documentation.
Coding tip
Look for explicit provider wording such as “tabes dorsalis” or “late neurosyphilis” before coding A52.11.
