Renal agenesis, unspecified

This code signifies the congenital absence of one or both kidneys, where the specific laterality (unilateral or bilateral) is not documented. It represents a severe developmental anomaly of the urinary system, often associated with other congenital malformations.

Apply this code when medical record documentation clearly states "renal agenesis" without specifying if it's unilateral or bilateral. This is typically used for initial diagnoses or when imaging reports confirm the absence of kidney tissue but lack laterality detail.

• Do not use if laterality (unilateral or bilateral) is specified; use the more specific codes (Q60.0, Q60.1).
• Ensure documentation explicitly states "agenesis" rather than "aplasia" or "hypoplasia," which have distinct codes.
• Sequence as a primary diagnosis when it is the reason for the encounter or a significant co-morbidity.
