Code Classification

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

H50.1 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of exotropia. The code is not specific and is NOT valid for the year 2024 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 Exotropia

Non-specific codes like H50.1 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for exotropia:

  • Use H50.10 for Unspecified exotropia - BILLABLE CODE

  • H50.11 for Monocular exotropia - NON-BILLABLE CODE

  • Use H50.111 for Monocular exotropia, right eye - BILLABLE CODE

  • Use H50.112 for Monocular exotropia, left eye - BILLABLE CODE

  • H50.12 for Monocular exotropia with A pattern - NON-BILLABLE CODE

  • Use H50.121 for Monocular exotropia with A pattern, right eye - BILLABLE CODE

  • Use H50.122 for Monocular exotropia with A pattern, left eye - BILLABLE CODE

  • H50.13 for Monocular exotropia with V pattern - NON-BILLABLE CODE

  • Use H50.131 for Monocular exotropia with V pattern, right eye - BILLABLE CODE

  • Use H50.132 for Monocular exotropia with V pattern, left eye - BILLABLE CODE

  • H50.14 for Monocular exotropia with other noncomitancies - NON-BILLABLE CODE

  • Use H50.141 for Monocular exotropia with other noncomitancies, right eye - BILLABLE CODE

  • Use H50.142 for Monocular exotropia with other noncomitancies, left eye - BILLABLE CODE

  • Use H50.15 for Alternating exotropia - BILLABLE CODE

  • Use H50.16 for Alternating exotropia with A pattern - BILLABLE CODE

  • Use H50.17 for Alternating exotropia with V pattern - BILLABLE CODE

  • Use H50.18 for Alternating exotropia with other noncomitancies - BILLABLE CODE

Clinical Information

  • 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.

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Divergent concomitant strabismus

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

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.
