ICD-10 Code H10.812 – Pingueculitis, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H10.812 – Pingueculitis, left eye
What it is
H10.812 identifies inflammation of a pinguecula in the left eye. A pinguecula is a yellowish conjunctival lesion, and pingueculitis means it has become irritated or inflamed.
Clinical signs
Findings commonly include localized redness, irritation, and a swollen or tender pinguecula on the conjunctiva. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents pingueculitis specifically in the left eye. It fits visits for an inflamed pinguecula with left-sided laterality clearly stated in the note. If the record only says conjunctivitis or pinguecula without inflammation, check documentation.
Do not use for
Do not use H10.812 for pinguecula without inflammation, or for conjunctivitis not linked to a pinguecula. If laterality is not documented or another eye is involved, check documentation.
Coding tip
Confirm both the inflammatory diagnosis and left-eye laterality in the provider note before assigning H10.812.
