Posterior dislocation of lens, right eye

This code signifies a condition where the crystalline lens of the right eye has become displaced backward from its normal position within the globe. This displacement can lead to significant visual impairment due to altered light refraction and potential secondary complications.

Use this code when documentation explicitly states a posterior dislocation of the lens in the patient's right eye. This typically occurs following trauma, but can also be spontaneous in cases of zonular weakness or rupture. Supporting documentation should include ophthalmological examination findings confirming the posterior displacement.

• Ensure laterality is accurately documented and coded; differentiate between right, left, and bilateral involvement.
• Distinguish between subluxation (partial displacement) and luxation (complete dislocation) of the lens.
• Look for underlying causes, such as trauma (e.g., S05.01XA), Marfan syndrome (Q87.40), or homocystinuria (E72.11), and code them as additional diagnoses when present and documented.
