Code Description

ICD-10 E34.50 is a billable code used to indicate a diagnosis of androgen insensitivity syndrome, unspecified.

Key Diagnostic Point:

Androgen Insensitivity Syndrome (AIS) is a genetic condition that affects sexual development before birth and during puberty. Individuals with AIS are genetically male (XY chromosomes) but have a resistance to androgens, the hormones responsible for male characteristics. This results in the development of female physical traits despite having male genetic makeup. The severity of the condition can vary; some individuals may have a complete form of the syndrome, leading to the absence of male genitalia and the presence of female external genitalia, while others may have partial insensitivity, resulting in ambiguous genitalia. During puberty, individuals with complete AIS typically do not develop secondary male sexual characteristics, such as facial hair or a deep voice, and may present with primary amenorrhea. The condition is often diagnosed through physical examination, hormonal testing, and genetic testing. Management may involve psychological support, hormone replacement therapy, and surgical interventions, depending on the individual’s needs and the severity of the condition.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in clinical presentation (complete vs. partial AIS)
  • Need for genetic testing and interpretation
  • Potential for associated conditions (e.g., testicular cancer)
  • Documentation of hormonal levels and physical examination findings

Audit Risk Factors

  • Inadequate documentation of genetic testing results
  • Failure to document the severity of androgen insensitivity
  • Lack of clarity in distinguishing between complete and partial forms
  • Insufficient details on associated conditions or complications

Specialty Focus

Medical Specialties

Endocrinology

Documentation Requirements

Thorough documentation of hormonal assays, physical examination findings, and genetic testing results.

Common Clinical Scenarios

Evaluation of patients with ambiguous genitalia, delayed puberty, or primary amenorrhea.

Billing Considerations

Endocrinologists must ensure that all hormonal levels are documented and interpreted correctly to support the diagnosis.

Pediatrics

Documentation Requirements

Detailed growth and development assessments, family history, and referral notes.

Common Clinical Scenarios

Assessment of children with suspected intersex conditions or abnormal sexual development.

Billing Considerations

Pediatricians should document any psychosocial impacts on the patient and family.

Coding Guidelines

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of androgen insensitivity syndrome, enabling better tracking of the condition and its management. This specificity aids in research and improves patient care by allowing for tailored treatment plans.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of androgen insensitivity syndrome, enabling better tracking of the condition and its management. This specificity aids in research and improves patient care by allowing for tailored treatment plans.

Frequently Asked Questions

What is the difference between complete and partial androgen insensitivity syndrome?

Complete androgen insensitivity syndrome results in female external genitalia and no male reproductive structures, while partial androgen insensitivity may present with ambiguous genitalia or some male characteristics.
