Q89.2

Congenital malformations of other endocrine glands

BILLABLE STATUSYes

Code Description

ICD-10 Q89.2 is a billable code used to indicate a diagnosis of congenital malformations of other endocrine glands.

Key Diagnostic Point:

Congenital malformations of other endocrine glands encompass a variety of conditions affecting glands such as the adrenal glands, spleen, and other rare endocrine structures. These malformations can lead to significant hormonal imbalances and metabolic disorders in affected individuals. For instance, adrenal gland malformations may result in adrenal insufficiency or hyperplasia, impacting growth and development in pediatric patients. Congenital skin malformations, while not directly endocrine, can sometimes be associated with underlying endocrine dysfunctions. Breast malformations can also occur, affecting psychosocial development and physical health. Accurate diagnosis often requires a multidisciplinary approach, including endocrinology, genetics, and pediatrics, to manage the complex interplay of symptoms and ensure appropriate treatment. Genetic syndromes, such as Turner syndrome or Klinefelter syndrome, may also present with associated endocrine gland malformations, necessitating comprehensive genetic evaluation and counseling.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in presentation and severity of malformations
  • Need for multidisciplinary documentation
  • Potential overlap with other congenital conditions
  • Requirement for genetic testing results

Audit Risk Factors

  • Inadequate documentation of the specific malformation
  • Failure to include associated conditions
  • Misclassification of congenital vs. acquired conditions
  • Lack of genetic testing documentation

Specialty Focus

Medical Specialties

Pediatrics

Documentation Requirements

Detailed growth and development assessments, hormonal evaluations, and family history.

Common Clinical Scenarios

Management of adrenal insufficiency in a newborn, evaluation of ambiguous genitalia, and monitoring of growth patterns in children with congenital malformations.

Billing Considerations

Pediatric coders must ensure that all relevant clinical findings are documented to support the diagnosis and any associated treatments.

Genetics

Documentation Requirements

Genetic testing results, family pedigree, and syndromic associations.

Common Clinical Scenarios

Genetic counseling for families with a history of congenital endocrine disorders, and evaluation of chromosomal abnormalities linked to endocrine malformations.

Billing Considerations

Genetic coders should focus on the relationship between genetic syndromes and endocrine malformations, ensuring accurate linkage in documentation.
