  • M43.6 is an ICD-10-CM code used for diagnosing Torticollis, a condition characterized by the involuntary contraction of the neck muscles leading to a twisted or tilted neck.
  • This code helps health professionals categorize and detail a patient's condition for medical records, epidemiological tracking, and insurance reimbursement purposes.

Additional coding or narrative description may be needed to capture specifics like congenital origin due to trauma, drug-induced, etc.
