ICD-10 Code H01.133 – Eczematous dermatitis of right eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.133 – Eczematous dermatitis of right eye, unspecified eyelid
What it is
This code identifies eczematous dermatitis affecting the right eye area, with the eyelid side not specified. Use it when documentation describes eczema-like inflammation around the right eye but does not name the upper or lower eyelid.
Clinical signs
Typical findings include redness, itching, scaling, and irritation of the periocular skin. Clinical features vary; refer to documentation for whether the eyelid is involved and whether the process is acute or chronic.
When to use this code
Use H01.133 when the record clearly documents eczematous dermatitis on the right eye region and does not specify which eyelid is affected. It is appropriate for outpatient, inpatient, or specialist notes that describe dermatitis, eczema, or eczematous changes limited to that site.
If the clinician specifies another eyelid location, bilateral involvement, or a different diagnosis, choose the documented code instead. Check documentation when the note only says “eye irritation” or “rash” without confirming eczematous dermatitis.
Do not use for
Do not use this code for allergic conjunctivitis, blepharitis, or nonspecific facial dermatitis. Check documentation if the condition is not clearly eczematous or if the eyelid side is not the right eye.
Coding tip
Code the exact eyelid laterality and specificity from the provider note; if the eyelid is named, do not default to unspecified eyelid.
