Cyclotropia, left eye

This code signifies a manifest strabismus where the left eye is rotated inward or outward around its anterior-posterior axis. This misalignment results in a torsional deviation of the left eye, meaning the top of the eye is tilted either nasally (incyclotropia) or temporally (excyclotropia).

Apply this code when documentation explicitly states cyclotropia affecting the left eye. This diagnosis is typically made during an ophthalmological examination, often involving specialized tests to assess ocular torsion. Supporting documentation should include findings of a manifest torsional deviation of the left eye.

• Ensure the documentation specifies "left eye" to differentiate from bilateral or right eye involvement.
• Do not confuse with other forms of strabismus like esotropia (inward horizontal deviation) or exotropia (outward horizontal deviation).
• Look for specific terms like "incyclotropia" or "excyclotropia" of the left eye, as these fall under the umbrella of cyclotropia.
