Code Description

ICD-10 Q55.21 is a billable code used to indicate a diagnosis of polyorchism.

Key Diagnostic Point:

Polyorchism, also known as supernumerary testes, is a rare congenital condition characterized by the presence of more than two testicles. This anomaly can occur alongside other genital malformations, such as cryptorchidism (undescended testicles) and hypospadias (abnormal urethral opening). The condition may lead to complications such as infertility, testicular torsion, or malignancy. Diagnosis typically involves imaging studies, such as ultrasound or MRI, to identify the number and location of the testes. Management may require surgical intervention, particularly if the additional testes are non-functional or pose a risk of complications. Polyorchism can be associated with other congenital anomalies, including ambiguous genitalia and various chromosomal abnormalities, necessitating a comprehensive evaluation of the patient’s genetic background and overall health. Accurate coding is essential for proper treatment planning and insurance reimbursement.

Audit Risk Factors

  • Inadequate documentation of associated anomalies
  • Failure to document imaging studies
  • Misclassification of the condition as cryptorchidism
  • Lack of genetic evaluation documentation

Pediatrics

Documentation Requirements

Pediatric documentation should include growth parameters, developmental milestones, and any associated congenital conditions.

Common Clinical Scenarios

Common scenarios include evaluation of ambiguous genitalia or undescended testes in newborns.

Billing Considerations

Consideration of the psychosocial impact on the family and the need for multidisciplinary care.

Genetics

Documentation Requirements

Genetic documentation should include family history, results of genetic testing, and any syndromic associations.

Common Clinical Scenarios

Genetic counseling for families with a history of congenital anomalies or when polyorchism is identified.

Billing Considerations

Consideration of chromosomal abnormalities that may be associated with polyorchism, such as Klinefelter syndrome.
