Unspecified astigmatism, right eye

This code indicates an uncorrected refractive error of the right eye where light rays entering the eye do not focus on a single point on the retina, resulting in blurred or distorted vision at all distances. The specific type or cause of the astigmatism is not documented.

This code is appropriate when the patient presents with astigmatism affecting the right eye, but the ophthalmologist or optometrist has not specified the type (e.g., myopic, hyperopic, mixed, irregular) in the medical record. It is used when documentation clearly indicates astigmatism in the right eye without further detail.

• Avoid using this code if the type of astigmatism (e.g., myopic, hyperopic) is documented; instead, use a more specific code from the H52.2 subcategory.
• Ensure laterality is clearly documented as "right eye" to support this specific code.
• Do not use this code if astigmatism affects both eyes or the left eye; specific codes exist for those scenarios.
