Exstrophy of urinary bladder, unspecified

This code signifies a congenital anomaly where the urinary bladder is exposed on the abdominal wall due to a defect in the anterior abdominal wall and bladder wall. It represents an unclosed bladder that is open to the outside, often accompanied by other pelvic floor and genitourinary malformations. This specific code indicates that the type or extent of exstrophy is not further specified in the medical record.

Use this code when documentation clearly indicates exstrophy of the urinary bladder but lacks details regarding the specific variant (e.g., classic, cloacal, or superior vesical fissure). This code is appropriate for initial diagnosis when further characterization is pending or when the physician's documentation simply states "exstrophy of bladder" without additional modifiers.

• Avoid using this code if the documentation specifies a particular type of exstrophy; instead, use a more specific code from the Q64.1 subcategory.
• Always review the entire medical record for any mention of associated anomalies, such as epispadias (Q64.0) or other genitourinary malformations, and code them separately.
• This code is typically a primary diagnosis for the initial presentation and management of the condition.
