H21.229
ICD-10-CMThis code signifies a non-inflammatory deterioration of the ciliary body, an integral part of the eye responsible for aqueous humor production and accommodation. This degeneration can lead to various ocular complications, including changes in intraocular pressure or visual disturbances. The "unspecified eye" designation indicates that the laterality of the condition is not documented.
Apply this code when documentation clearly states degeneration of the ciliary body without specifying the affected eye (right or left). This is appropriate when the physician's notes indicate the condition but lack laterality, or if the condition is bilateral and the documentation does not differentiate.
