2025 ICD-10-CM code H02.22
Mechanical lagophthalmos.
Medical necessity for treatment of mechanical lagophthalmos is established by the presence of symptoms, the severity of the condition, and the potential for corneal complications. Treatment is necessary to protect the cornea from exposure, dryness, and potential infection or ulceration.
Clinicians should evaluate patients presenting with the inability to close their eyes completely, foreign body sensation, increased tearing, dry eyes, blurred vision, and eye pain, especially in the morning, for mechanical lagophthalmos. Diagnosis involves medical history, symptom assessment, and eye/eyelid examination. Treatment includes artificial tears, ointments, antibiotics (if corneal infection is present), and potentially surgery like tarsorrhaphy, gold weight implants, or corrective procedures for underlying structural issues.

In simple words: Mechanical lagophthalmos is the inability to fully close your eyelids due to a physical problem like a tumor or structural defect affecting the muscle that controls eyelid closure. This can lead to dry eyes, irritation, and potential damage to the cornea.
Mechanical lagophthalmos refers to the inability to close the eyelids completely due to a tumor or other structural defect, which causes dysfunction of the orbicularis oculi muscle.
Example 1: A patient presents with a tumor on the upper eyelid, causing an inability to fully close the eye. The diagnosis is mechanical lagophthalmos (H02.22)., Following trauma to the face, a patient experiences difficulty closing their left eye due to nerve damage. This is coded as mechanical lagophthalmos (H02.22)., A patient with a history of thyroid eye disease develops lagophthalmos due to scarring and retraction of the eyelid. This condition is documented as mechanical lagophthalmos (H02.22).
Documentation should include the type of lagophthalmos (mechanical), the location (which eye is affected), laterality (left, right, or bilateral), the underlying cause (e.g., tumor, trauma, scarring), and the associated symptoms. Any diagnostic tests and treatments should also be recorded.
