Other interstitial and deep keratitis, right eye

This code signifies inflammation affecting the deeper layers of the cornea (stroma or endothelium) in the right eye, not specifically classified as other forms of interstitial or deep keratitis. This condition can lead to corneal scarring, vision impairment, and photophobia.

Apply this code when documentation specifies interstitial or deep keratitis of the right eye that does not fit more specific classifications (e.g., herpetic, syphilitic, or disciform). Supporting documentation should clearly indicate the affected eye and the nature of the corneal inflammation, ruling out other specific etiologies.

• Ensure laterality is clearly documented as "right eye" to support this specific code.
• Avoid using this code if a more specific type of interstitial or deep keratitis (e.g., H16.2x for other interstitial keratitis) is identified.
• Always review the medical record for an underlying cause, as an additional code for the etiology may be required.
