Code Description

ICD-10 N46.12 is a billable code used to indicate a diagnosis of oligospermia due to extratesticular causes.

Key Diagnostic Point:

Oligospermia refers to a condition characterized by a lower than normal sperm count in the ejaculate, which can significantly impact male fertility. When classified under N46.12, it indicates that the oligospermia is due to extratesticular causes, meaning that the issue arises outside the testes. Common extratesticular causes include conditions such as hydrocele, which can impede sperm transport, and various penile disorders that may affect ejaculation. Testicular disorders like orchitis, which is inflammation of the testes, can also contribute to oligospermia by affecting sperm production. Additionally, male infertility can stem from hormonal imbalances or anatomical abnormalities that are not directly related to the testes. Proper diagnosis often requires a thorough evaluation of the male reproductive system, including hormonal assessments and imaging studies. Andrological management may involve addressing underlying conditions, lifestyle modifications, or assisted reproductive technologies to improve fertility outcomes.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between testicular and extratesticular causes of oligospermia.
  • Understanding the interplay of various conditions affecting male fertility.
  • The need for comprehensive documentation to support the diagnosis.
  • Potential overlap with other codes related to male infertility.

Audit Risk Factors

  • Inadequate documentation of the underlying extratesticular cause.
  • Failure to provide evidence of diagnostic testing performed.
  • Misclassification of oligospermia as primary infertility without supporting details.
  • Lack of clarity in treatment plans related to the diagnosis.
