ICD-10 | Diplopia (H53. 2)
A visual symptom in which a single object is perceived by the visual cortex as two objects rather than one. Disorders associated with this condition include refractive errors; strabismus; oculomotor nerve diseases; trochlear nerve diseases; abducens nerve diseases; and diseases of the brain stem and occipital lobe.
Diagnosis requires a clinical examination involving eye movement tests and, depending on the suspected cause, possibly blood tests or imaging. Treatment focuses on reducing double vision directly, such as by wearing eye patches or prism lens glasses, as well as on addressing the underlying condition.
The two most common binocular vision disorders are strabismus (crossed eyes) and amblyopia (lazy eye). These disorders often present themselves in young children. The two conditions often occur together, but can present individually.
ICD-10 code H53. 2 for Diplopia is a medical classification as listed by WHO under the range - Diseases of the eye and adnexa .
H53. 9 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM H53.
Binocular diplopia occurs when both eyes are open and resolves when either eye is closed. It is caused by a misalignment of the eyes, also called strabismus. Conditions that affect the cranial nerves supplying the muscles that control the eyes can cause binocular diplopia.
While the double vision is occurring, cover one eye. If the double vision disappears while covering either eye you have binocular diplopia. In monocular diplopia, the double vision goes away when the affected or “bad” eye is covered, and returns when the unaffected or “good” eye is covered.
Horizontal diplopia is binocular if it disappears with either eye closed; this suggests that the underlying problem is due to ocular misalignment. Monocular diplopia persists with 1 eye closed, is not due to ocular misalignment, and is usually due to local eye disease or refractive error.
Binocular vision dysfunction is an ocular condition that occurs when the eyes don't align properly with one another. Although our brains may try to correct this misalignment, it isn't without considerable effort and this results in a range of symptoms that are associated with the condition.
Binocular vision means seeing with two eyes but, as ophthalmologists, we take it to mean more. We assume that using two eyes together and gaining a single image is better than using one eye at a time.
For a monocular, it has only one lens that you can hold up to one eye (you can choose to use your left or right eye based on your personal preference), while a binocular comes with 2 lens which you can hold up to both eyes. “A monocular is simply half a binocular.”
