Spasm of accommodation, left eye

This code signifies an involuntary, sustained contraction of the ciliary muscle in the left eye, leading to a fixed and excessive focusing effort. This spasm results in a pseudomyopia, where the eye is constantly accommodated for near vision, causing blurred distance vision and eye strain. It is a functional disorder of ocular accommodation.

Apply this code when documentation clearly indicates a diagnosis of accommodative spasm specifically affecting the left eye. This typically occurs in patients presenting with fluctuating vision, asthenopia, and a myopic shift that is not corrected by standard refractive lenses. Supporting documentation should include ophthalmological examination findings confirming the ciliary muscle spasm.

• Ensure laterality is precisely documented; do not use for bilateral or unspecified eye involvement.
• Differentiate from true myopia (H52.1-) or other refractive errors, as this is a functional spasm.
• Consider co-reporting with codes for associated symptoms like asthenopia (H53.14) if documented.
