Code Description

ICD-10 E29.1 is a billable code used to indicate a diagnosis of testicular hypofunction.

Key Diagnostic Point:

Testicular hypofunction refers to a condition characterized by inadequate production of testosterone and other hormones by the testes. This condition can result from various underlying factors, including disorders of the hypothalamus or pituitary gland, which may fail to stimulate the testes adequately. Additionally, adrenal disorders can contribute to hormonal imbalances that affect testicular function. Symptoms may include reduced libido, erectile dysfunction, infertility, and changes in secondary sexual characteristics. The diagnosis often involves a combination of clinical evaluation, hormone level testing, and imaging studies to assess the structure and function of the testes. Treatment may involve hormone replacement therapy or addressing the underlying causes, such as managing pituitary or adrenal disorders. Accurate coding is essential for proper reimbursement and to ensure that the patient's medical history reflects the complexity of their condition.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between primary and secondary testicular hypofunction
  • Understanding the interplay between endocrine glands (pituitary, adrenal, and testicular)
  • Identifying associated conditions that may complicate diagnosis
  • Navigating the documentation requirements for hormone level testing

Audit Risk Factors

  • Inadequate documentation of hormone levels and clinical symptoms
  • Failure to specify the underlying cause of hypofunction
  • Misclassification of primary vs. secondary hypofunction
  • Lack of follow-up documentation for treatment efficacy

Endocrinology

Documentation Requirements

Detailed hormone level assessments, patient history, and treatment plans.

Common Clinical Scenarios

Evaluation of male patients presenting with infertility or low testosterone symptoms.

Billing Considerations

Endocrinologists must document the results of endocrine testing and any imaging studies performed.

Urology

Documentation Requirements

Clinical findings related to sexual function, fertility assessments, and any surgical interventions.

Common Clinical Scenarios

Management of patients with erectile dysfunction or infertility linked to testicular function.

Billing Considerations

Urologists should ensure that all relevant hormonal evaluations are included in the patient’s records.
