Code Description

ICD-10 G56.31 is a billable code used to indicate a diagnosis of lesion of radial nerve, right upper limb.

Key Diagnostic Point:

A lesion of the radial nerve in the right upper limb can result from various etiologies, including trauma, compression, or systemic diseases. The radial nerve is responsible for the motor function of the extensor muscles of the forearm and the sensory innervation of the posterior aspect of the arm and forearm, as well as part of the hand. Symptoms may include wrist drop, weakness in extending the elbow, and sensory loss in the areas supplied by the nerve. Diagnosis typically involves a thorough clinical examination, nerve conduction studies, and electromyography to assess the extent of the lesion and the functionality of the nerve. Treatment may vary from conservative management, such as physical therapy and splinting, to surgical intervention in cases of severe compression or injury. Accurate coding is essential for appropriate reimbursement and to reflect the complexity of the patient's condition.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in presentation and symptoms
  • Need for detailed documentation of nerve function
  • Differentiation from other neuropathies
  • Potential for co-existing conditions affecting coding

Audit Risk Factors

  • Inadequate documentation of symptoms and clinical findings
  • Failure to specify laterality
  • Misidentification of the nerve involved
  • Lack of supporting diagnostic tests
