ICD-10 Code H02.36 – Blepharochalasis left eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.36 – Blepharochalasis left eye, unspecified eyelid
What it is
Use this code for blepharochalasis affecting the left eye when the eyelid side is documented but the specific eyelid is not. It refers to recurrent eyelid swelling that can lead to lax, thinned eyelid tissue.
Clinical signs
Typical findings include episodic eyelid edema, stretching of eyelid skin, and possible ptosis or redundant tissue over time. Clinical features vary; refer to documentation.
When to use this code
Assign H02.36 when the record clearly states blepharochalasis of the left eye and does not identify a particular eyelid. Use it when the diagnosis is established by the clinician, not when only nonspecific eyelid swelling is noted. Check documentation if laterality or eyelid detail is missing.
Do not use for
Do not use this code for general eyelid edema, trauma, infection, or other eyelid disorders without blepharochalasis. If the right eye, both eyes, or a specific eyelid is documented instead, select the matching code.
Coding tip
Confirm both laterality and eyelid specificity in the note before coding, because H02.36 is only for left-eye blepharochalasis with unspecified eyelid.
