Code Description

ICD-10 Q71.891 is a billable code used to indicate a diagnosis of other reduction defects of right upper limb.

Key Diagnostic Point:

Reduction defects of the right upper limb encompass a variety of congenital malformations where there is a partial or complete absence of one or more structures of the limb. These defects can result from genetic factors, environmental influences, or a combination of both. Clinically, these conditions may present as hypoplasia (underdevelopment) or aplasia (absence) of the arm, forearm, or hand. Associated features may include limb length discrepancies, functional limitations, and cosmetic concerns. The severity of the defect can vary widely, impacting the patient's ability to perform daily activities. Early diagnosis and intervention are crucial for optimizing functional outcomes, which may include surgical correction, prosthetic fitting, and physical therapy. Understanding the underlying genetic or environmental causes is essential for comprehensive management and counseling of affected families.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in presentation and severity of limb reduction defects.
  • Need for detailed documentation of associated anomalies.
  • Differentiation from other congenital limb conditions.
  • Potential for multiple coding based on associated conditions.

Audit Risk Factors

  • Inadequate documentation of limb measurements and functional assessments.
  • Failure to capture associated congenital anomalies.
  • Misclassification of limb reduction severity.
  • Inconsistent coding practices across providers.
