ICD-10 Code H16.313 – Corneal abscess, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H16.313 – Corneal abscess, bilateral
What it is
H16.313 identifies an abscess of the cornea in both eyes. It means a localized corneal infection with pus or tissue breakdown documented as bilateral.
Clinical signs
Typical findings include eye pain, redness, tearing, photophobia, and reduced vision. Clinical features vary; refer to documentation for confirmed bilateral corneal abscess.
When to use this code
Use this code when the provider documents corneal abscess in both eyes, or bilateral corneal infection with abscess formation. It is appropriate when the condition is clearly stated in the assessment, problem list, or discharge diagnosis. Check documentation if laterality is unclear.
Do not use for
Do not use it for unilateral corneal abscess, corneal ulcer without abscess, or nonspecific keratitis. Do not assign it if the record does not confirm bilateral involvement.
Coding tip
Always verify laterality in the note, since H16.313 is specific to both eyes.
