Infertility due to extratesticular causes

This code signifies male infertility stemming from factors outside the testes themselves. These extratesticular causes can include issues with sperm transport, hormonal imbalances affecting sperm production, or ejaculatory dysfunction, rather than primary testicular failure.

Assign this code when documentation clearly indicates male infertility and diagnostic workup has ruled out intrinsic testicular pathology. This applies to conditions such as obstructive azoospermia, hypogonadotropic hypogonadism, or retrograde ejaculation, where the testes are functionally capable but other factors impede fertility.

• Ensure documentation specifies the extratesticular cause; if unknown, consider 606.9 (Infertility, unspecified male).
• Do not use for primary testicular failure (e.g., Klinefelter's syndrome, cryptorchidism with testicular atrophy); those would be coded elsewhere.
• Code any underlying conditions contributing to the extratesticular infertility (e.g., pituitary adenoma for hypogonadism) as additional diagnoses.
