2026 ICD-10-CM Diagnosis Code H50

Other strabismus

ICD-10-CM Code:
H50
ICD-10 Code for:
Other strabismus
Is Billable?
Not Valid for Submission
Code Navigator:

H50 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity from the list below for a diagnosis of other strabismus. The code is not specific and is NOT valid for the year 2026 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Other strabismus

Non-specific codes like H50 require more digits to indicate the appropriate level of specificity. Consider using any of the following billable codes with a higher level of specificity when coding for other strabismus:

  • H50.0 for Esotropia

  • Use H50.00 for Unspecified esotropia

  • H50.04 for Monocular esotropia with other noncomitancies

  • Use H50.05 for Alternating esotropia

  • Use H50.06 for Alternating esotropia with A pattern

  • Use H50.07 for Alternating esotropia with V pattern

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.

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.
