Congenital lens malformation, unspecified

This code signifies a birth defect affecting the lens of the eye, where the specific nature of the malformation is not documented. It encompasses any structural anomaly of the crystalline lens present at birth, such as an abnormally shaped, sized, or positioned lens, when further detail is unavailable.

Apply this code when medical records indicate a congenital abnormality of the ocular lens, but the physician has not specified the exact type of malformation (e.g., aphakia, microphakia, coloboma of lens). Documentation should clearly state a congenital lens issue without further descriptive detail.

• Do not use if a more specific congenital lens malformation is documented (e.g., Q12.0 for congenital cataract).
• Ensure the documentation explicitly states "congenital" to differentiate from acquired lens conditions.
• Consider sequencing this code after any associated congenital anomalies of the eye or systemic syndromes, if applicable.
