Diplopia

This code represents the perception of two images of a single object, commonly known as double vision. It indicates a binocular or monocular visual disturbance where the eyes fail to properly align or coordinate, leading to overlapping or separated images.

Use this code when documentation explicitly states a patient is experiencing double vision. This applies to both monocular diplopia (double vision in one eye) and binocular diplopia (double vision that resolves when one eye is covered). Supporting documentation includes patient complaints, ophthalmological examination findings, and physician notes describing the visual disturbance.

• Always specify laterality if documented (e.g., right, left, bilateral) using an additional character if applicable for more specific codes within the H53 category.
• Do not confuse with blurred vision (R48.3) or other visual disturbances unless double vision is explicitly stated.
• Code any underlying cause of the diplopia first, if known and documented, as this code often represents a symptom.
