Ocular torticollis

Ocular torticollis describes an abnormal head posture (e.g., head tilt, turn, or chin elevation/depression) adopted by a patient to compensate for an underlying ophthalmologic condition, such as strabismus, nystagmus, or ptosis, to achieve binocular vision or improve visual acuity. This compensatory head position is an attempt to align the eyes or move the eyes into a field of gaze where vision is optimized. It is distinct from musculoskeletal or neurological causes of torticollis.

This code is appropriate when documentation explicitly links the torticollis to an ocular etiology. It should be used when a patient presents with a head tilt or turn that is determined by an ophthalmologist to be a compensatory mechanism for an eye movement disorder or visual impairment. Supporting documentation will often include ophthalmological examination findings detailing the underlying ocular condition.

• Do not use this code for torticollis stemming from congenital, psychogenic, spasmodic, or birth injury causes, as these have specific Excludes1 codes.
• Always code the underlying ocular condition (e.g., strabismus, nystagmus) first, as the ocular torticollis is a manifestation of that primary condition.
• Ensure the physician's documentation clearly states the torticollis is "ocular" or "compensatory due to [ocular condition]" to support code assignment.
