Paresis of accommodation, unspecified eye

This code signifies a paralysis or weakness of the ciliary muscle, impairing the eye's ability to focus on near objects. It results in blurred vision for close-up tasks due to the eye's inability to change its refractive power. This condition is distinct from presbyopia, which is age-related.

Use this code when documentation indicates paresis or paralysis of accommodation without specifying the affected eye. This diagnosis is typically supported by findings from an ophthalmological examination, such as cycloplegic refraction or accommodative amplitude testing, confirming reduced or absent accommodative power.

• Do not use this code if the laterality (right or left eye) is documented; instead, use the more specific H52.521 or H52.522.
• Differentiate from presbyopia (H52.4), which is a normal age-related decline in accommodative ability.
• Consider coding any underlying systemic conditions or neurological disorders that may be causing the paresis of accommodation.
