ICD-10 Code H02.823 – Cysts of right eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.823 – Cysts of right eye, unspecified eyelid
What it is
Use this code for a cyst located on the right eyelid when the record does not specify a more exact eyelid site. It describes a benign, localized eyelid cyst affecting the right eye area.
Clinical signs
Typical findings include a small, well-defined eyelid lump, mild swelling, or cosmetic concern. Clinical features vary; refer to documentation if the note does not clearly identify the lesion as a cyst.
When to use this code
Use H02.823 when the provider documents a cyst of the right eyelid and does not name the upper or lower lid. It is appropriate for office, outpatient, or specialist notes that clearly identify the right side. If the chart says only “eyelid cyst,” check documentation for laterality and site.
Do not use for
Do not use this code for left eyelid cysts, bilateral lesions, or cysts with a more specific eyelid location. Check documentation if the lesion is described as a chalazion, stye, or another non-cyst eyelid disorder.
Coding tip
Confirm right-sided laterality and whether the upper or lower eyelid is unspecified before assigning H02.823.
