ICD-10 Code H02.229 – Mechanical lagophthalmos unspecified eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.229 – Mechanical lagophthalmos unspecified eye, unspecified eyelid
What it is
H02.229 identifies lagophthalmos caused by a mechanical problem, meaning the eyelids cannot close fully because of a physical obstruction or eyelid abnormality. The record does not specify which eye or eyelid is affected.
Clinical signs
Typical findings include incomplete eyelid closure, visible sclera during attempted closure, and exposure-related eye irritation. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents mechanical lagophthalmos and does not identify the side or eyelid. It may apply when eyelid closure is limited by scarring, mass effect, or other mechanical causes. Check documentation for the exact anatomic site and cause.
Do not use for
Do not use this code for paralytic lagophthalmos or cases where the chart specifies a different eye or eyelid. If the note only describes exposure symptoms without confirming mechanical lagophthalmos, do not assign it.
Coding tip
Code the documented cause and laterality separately when available; otherwise, use the unspecified code only if the record supports mechanical lagophthalmos.
