Disorders of iris and ciliary body in diseases classified elsewhere (H22)

ICD-10 code H22 is used to classify disorders affecting the iris and ciliary body that occur as part of other diseases. These codes help identify eye problems linked specifically to systemic conditions rather than primary eye diseases.

This section includes conditions such as uveitis associated with juvenile idiopathic arthritis (JIA), whether antinuclear antibody positive or negative, and various onset types (persistent or extended). It also covers uveitis linked to infections like Human T-cell Lymphotropic Virus Type 1 and inflammatory disorders such as ankylosing spondylitis, which may co-occur with anterior uveitis. Synonyms like “Uveitis due to juvenile idiopathic arthritis” or “Ankylosing spondylitis co-occurrent with anterior uveitis” directly relate to this code. Medical coders use the ICD-10 code for disorders of the iris and ciliary body in diseases classified elsewhere to capture these secondary eye complications accurately, ensuring precise documentation of systemic disease effects on the eye.

Instructional Notations

Code First

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.

  • gout M1A M10
  • leprosy A30
  • parasitic disease B89
