Code Description

ICD-10 Q71.21 is a billable code used to indicate a diagnosis of congenital absence of both forearm and hand, right upper limb.

Key Diagnostic Point:

Congenital absence of both the forearm and hand on the right upper limb is a significant limb reduction defect that occurs during fetal development. This condition is characterized by the complete absence of the forearm and hand, resulting in a functional impairment of the right upper limb. The etiology of this condition can be multifactorial, including genetic factors, environmental influences, or teratogenic exposures during pregnancy. Clinically, affected individuals may exhibit varying degrees of functional limitations, which can impact daily activities and overall quality of life. Early intervention, including physical therapy and occupational therapy, is crucial to maximize the use of the remaining limb and to facilitate adaptive strategies for daily living. Surgical options may also be considered to improve function or cosmetic appearance. Accurate coding of this condition is essential for appropriate management and resource allocation in pediatric care.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in clinical presentation and severity of limb absence.
  • Need for detailed documentation of associated anomalies.
  • Potential for co-occurring congenital conditions.
  • Variations in coding based on laterality and specific limb involvement.

Audit Risk Factors

  • Inadequate documentation of the absence and functional limitations.
  • Failure to report associated congenital anomalies.
  • Misclassification of limb reduction defects.
  • Inconsistent use of laterality in coding.
