Oligospermia due to obstruction of efferent ducts

This code signifies a male infertility factor characterized by a low sperm count (oligospermia) that is specifically caused by a physical blockage within the efferent ducts, which are responsible for transporting sperm from the testes. This obstruction prevents the normal release of sperm into the ejaculate, leading to reduced sperm concentration.

Use this code when documentation clearly indicates oligospermia and diagnostic workup, such as semen analysis and imaging (e.g., scrotal ultrasound, vasography), confirms an obstruction of the efferent ducts as the underlying etiology. This code is appropriate for patients undergoing evaluation and treatment for male factor infertility attributed to this specific anatomical issue.

• Ensure documentation specifies "obstruction of efferent ducts" as the cause of oligospermia, not just general obstructive azoospermia.
• Distinguish this from other forms of oligospermia (e.g., non-obstructive, idiopathic) which have different codes.
• Consider sequencing this code as a primary diagnosis when the patient presents for evaluation or treatment directly related to this condition.
