ICD-10 Code H57.81 – Brow ptosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H57.81 – Brow ptosis
What it is
Brow ptosis is a drooping of the eyebrow below its normal position. It can narrow the upper field of vision or create a heavy, tired appearance around the eyes.
Clinical signs
Typical findings include a low-set brow, asymmetry between the two sides, and possible upper eyelid hooding. Clinical features vary; refer to documentation.
When to use this code
Use H57.81 when the provider documents brow ptosis or eyebrow descent as the diagnosis. It may be reported when the condition is evaluated for visual obstruction, facial asymmetry, or preoperative assessment. Confirm that the record identifies brow ptosis specifically, not only eyelid droop.
Do not use for
Do not use this code for ptosis of the eyelid, blepharoptosis, or generalized facial weakness unless brow ptosis is specifically documented. Check documentation if the note is nonspecific.
Coding tip
Code from the provider’s exact wording and do not assume brow ptosis from eyelid droop alone.
