Lens-induced iridocyclitis, right eye

This code signifies inflammation of the iris and ciliary body (iridocyclitis) that is directly caused by the presence of lens material within the eye. This typically occurs following trauma, surgery, or in cases of hypermature cataracts where lens proteins leak into the anterior chamber, triggering an immune response.

Apply this code when documentation clearly indicates iridocyclitis resulting from lens material exposure, specifically affecting the right eye. This diagnosis is often made after cataract surgery complications, lens dislocation, or penetrating ocular injury involving the lens.

• Ensure documentation specifies the right eye; use H20.22 for the left eye and H20.23 for bilateral involvement.
• Distinguish from other forms of iridocyclitis (e.g., infectious, autoimmune) by confirming the lens-induced etiology.
• Code any underlying cause of the lens material exposure (e.g., traumatic cataract, complicated cataract extraction) as a primary diagnosis if applicable.
