Code Classification

  • Diseases of the eye and adnexa
    (H00–H59)
    • Disorders of ocular muscles, binocular movement, accommodation and refraction
      (H49-H52)
      • Other strabismus
        (H50)

H50.9 is a billable diagnosis code used to specify a medical diagnosis of unspecified strabismus. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like H50.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Clinical Classification

Clinical Information

  • Esotropia

    a form of ocular misalignment characterized by an excessive convergence of the visual axes, resulting in a "cross-eye" appearance. an example of this condition occurs when paralysis of the lateral rectus muscle causes an abnormal inward deviation of one eye on attempted gaze.
  • Exotropia

    a form of ocular misalignment where the visual axes diverge inappropriately. for example, medial rectus muscle weakness may produce this condition as the affected eye will deviate laterally upon attempted forward gaze. an exotropia occurs due to the relatively unopposed force exerted on the eye by the lateral rectus muscle, which pulls the eye in an outward direction.
  • Strabismus

    misalignment of the visual axes of the eyes. in comitant strabismus the degree of ocular misalignment does not vary with the direction of gaze. in noncomitant strabismus the degree of misalignment varies depending on direction of gaze or which eye is fixating on the target. (miller, walsh & hoyt's clinical neuro-ophthalmology, 4th ed, p641)
  • Hypertelorism

    abnormal increase in the interorbital distance due to overdevelopment of the lesser wings of the sphenoid.
  • Open Bite

    a condition in which certain opposing teeth fail to establish occlusal contact when the jaws are closed.
  • Mongolian Spot

    a bluish-gray to gray-brown benign, melanocytic nevus found usually in the lumbosacral region of dark-skinned people, especially those of east asian ancestry. it is usually congenital or appears shortly after birth, and disappears in childhood.
  • Lumbosacral Region

    region of the back including the lumbar vertebrae, sacrum, and nearby structures.

Convert H50.9 to ICD-9-CM

  • ICD-9-CM Code: 378.9 - Eye movemnt disorder NOS
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education


Eye Movement Disorders

When you look at an object, you're using several muscles to move both eyes to focus on it. If you have a problem with the muscles, the eyes don't work properly.

There are many kinds of eye movement disorders. Two common ones are:

  • Strabismus - a disorder in which the two eyes don't line up in the same direction. This results in "crossed eyes" or "walleye."
  • Nystagmus - fast, uncontrollable movements of the eyes, sometimes called "dancing eyes"

Some eye movement disorders are present at birth. Others develop over time and may be associated with other problems, such as injuries. Treatments include glasses, patches, eye muscle exercises, and surgery. There is no cure for some kinds of eye movement disorders, such as most kinds of nystagmus.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
