Code Description

ICD-10 Q38.2 is a billable code used to indicate a diagnosis of macroglossia.

Key Diagnostic Point:

Macroglossia is a congenital condition characterized by an abnormally large tongue, which can lead to various complications, particularly in infants and children. This condition may be isolated or associated with other congenital malformations, including syndromes such as Down syndrome, Beckwith-Wiedemann syndrome, and others. The enlarged tongue can obstruct the airway, complicating breathing and feeding, and may also affect speech development. In some cases, macroglossia can be a result of underlying genetic abnormalities or endocrine disorders. Diagnosis typically involves clinical examination and may require imaging studies to assess the extent of the enlargement and its impact on surrounding structures. Management may include surgical intervention to reduce the size of the tongue if it causes significant functional impairment. Understanding the implications of macroglossia is crucial for pediatricians and specialists in genetics, as it can be a marker for more complex syndromic presentations.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in associated congenital conditions
  • Potential for airway obstruction requiring urgent intervention
  • Need for multidisciplinary management involving pediatrics and genetics
  • Documentation of associated syndromes or malformations

Audit Risk Factors

  • Inadequate documentation of associated conditions
  • Failure to specify the severity of macroglossia
  • Misclassification of macroglossia as an acquired condition
  • Lack of clarity in the treatment plan and follow-up
