About H20.8
H20.8 is the ICD-10-CM diagnosis code for other iridocyclitis. It belongs to category H20 (iridocyclitis), block H15-H22 (disorders of sclera, cornea, iris and ciliary body) and chapter 7 (diseases of the eye and adnexa). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.
Within H20, choose H20.8 (Other iridocyclitis) only when documentation doesn't support a more specific option: acute and subacute iridocyclitis (H20.0), chronic iridocyclitis (H20.1), Lens-induced iridocyclitis (H20.2) and unspecified iridocyclitis (H20.9).
To report this condition, pick the subcode that matches the documentation: H20.81 (cyclitis) and H20.82 (syndrome).
The conditions in its Excludes2 note aren't part of H20.8, but may be coded alongside it if the patient has both: glaucomatocyclitis crises (H40.4-), posterior cyclitis (H30.2-) and sympathetic uveitis (H44.13-).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
