Code Classification

  • Diseases of the eye and adnexa
    (H00–H59)
    • Disorders of sclera, cornea, iris and ciliary body
      (H15-H22)
      • Iridocyclitis
        (H20)

H20.8 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of other iridocyclitis. 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 Other iridocyclitis

Non-specific codes like H20.8 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 other iridocyclitis:

  • H20.81 for Fuchs' heterochromic cyclitis - NON-BILLABLE CODE

  • Use H20.811 for Fuchs' heterochromic cyclitis, right eye - BILLABLE CODE

  • Use H20.812 for Fuchs' heterochromic cyclitis, left eye - BILLABLE CODE

  • Use H20.813 for Fuchs' heterochromic cyclitis, bilateral - BILLABLE CODE

  • Use H20.819 for Fuchs' heterochromic cyclitis, unspecified eye - BILLABLE CODE

  • H20.82 for Vogt-Koyanagi syndrome - NON-BILLABLE CODE

  • Use H20.821 for Vogt-Koyanagi syndrome, right eye - BILLABLE CODE

  • Use H20.822 for Vogt-Koyanagi syndrome, left eye - BILLABLE CODE

  • Use H20.823 for Vogt-Koyanagi syndrome, bilateral - BILLABLE CODE

  • Use H20.829 for Vogt-Koyanagi syndrome, unspecified eye - BILLABLE CODE

Clinical Information

  • Iridocyclitis

    acute or chronic inflammation of the iris and ciliary body characterized by exudates into the anterior chamber, discoloration of the iris, and constricted, sluggish pupil. symptoms include radiating pain, photophobia, lacrimation, and interference with vision.

  • Chronic Iridocyclitis|Chronic Uveitis

    uveitis that is usually insidious in onset, bilateral, and can be asymptomatic, most often affecting the anterior uveal tract, including the iris and ciliary body, and can result in long-term complications. it is most commonly associated with certain forms of juvenile idiopathic arthritis, but may occur independent of arthritis.

  • Iridocyclitis

    inflammation of the iris and the ciliary body.

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.


Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
  • glaucomatocyclitis crises H40.4
  • posterior cyclitis H30.2
  • sympathetic uveitis H44.13

Patient Education


Eye Diseases

Some eye problems are minor and don't last long. But some can lead to a permanent loss of vision.

Common eye problems include:

  • Refractive errors
  • Cataracts - clouded lenses
  • Optic nerve disorders, including glaucoma
  • Retinal disorders - problems with the nerve layer at the back of the eye
  • Macular degeneration - a disease that destroys sharp, central vision
  • Diabetic eye problems
  • Conjunctivitis - an infection also known as pink eye

Your best defense is to have regular checkups, because eye diseases do not always have symptoms. Early detection and treatment could prevent vision loss. See an eye care professional right away if you have a sudden change in vision, if everything looks dim, or if you see flashes of light. Other symptoms that need quick attention are pain, double vision, fluid coming from the eye, and inflammation.
