Paresis of accommodation, left eye

This code indicates a partial or complete paralysis of the ciliary muscle in the left eye, leading to an inability to properly focus on near objects. This condition impairs the eye's ability to change its refractive power, resulting in blurred vision at close range.

Use this code when documentation specifies paresis or paralysis of accommodation affecting the left eye. This typically occurs due to neurological conditions, trauma, or certain medications. Supporting documentation should clearly state the laterality and the nature of the accommodative dysfunction.

• Ensure laterality is clearly documented as "left eye" to support this specific code.
• Distinguish from spasm of accommodation (H52.51-) which is an over-contraction, not paresis.
• Code any underlying cause of the paresis of accommodation if known and documented.
