Chorioretinal disorders in diseases classified elsewhere (H32)
ICD-10 code H32 is used to classify chorioretinal disorders when they occur as part of other diseases, rather than as primary eye conditions. This code specifically identifies eye complications involving the retina and choroid that result from systemic illnesses.
Chorioretinal disorders in diseases classified elsewhere cover conditions like renal retinopathy caused by chronic kidney disease, and various infectious retinitis types, including cytomegaloviral retinitis and infections related to Histoplasma capsulatum or Histoplasma duboisii. Sometimes called ocular histoplasmosis syndrome, histo spot, or cryptococcal choroiditis, these disorders indicate retinal inflammation or damage secondary to systemic infections or diseases. Knowing these synonyms helps medical coders link underlying diseases to eye involvement correctly, ensuring accurate coding for conditions such as fungal choroiditis or parasitic choroiditis. The ICD-10 code H32 is essential for capturing these complex cases where retinal problems stem from broader health issues, helping guide treatment and documentation.

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.
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.
