ICD-10 Code H02.726 – Madarosis of left eye, unspecified eyelid and periocular area (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.726 – Madarosis of left eye, unspecified eyelid and periocular area
What it is
H02.726 identifies loss of eyelashes or eyebrow hair on the left eye area when the eyelid and periocular site are not otherwise specified. Use it for documented madarosis affecting the left side only.
Clinical signs
Typical findings include partial or complete absence of lashes or brows around the left eye. Clinical features vary; refer to documentation for whether the loss is localized, diffuse, or associated with eyelid disease.
When to use this code
Use this code when the record clearly states madarosis of the left eye and does not identify a more specific eyelid or periocular diagnosis. It is appropriate when the provider documents hair loss in that region without another explained cause.
If the note only says eyelash loss, eyebrow thinning, or periocular alopecia, confirm that the left side is specified before assigning H02.726. Check documentation if laterality or site is unclear.
Do not use for
Do not use this code for generalized hair loss, bilateral madarosis, or conditions limited to the scalp. Do not use it when the chart documents a different eyelid disorder or a more specific cause.
Coding tip
Verify laterality and anatomic location in the provider note before coding, because H02.726 is specific to the left eye and unspecified eyelid/periocular area.
