Code Description

ICD-10 G57.82 is a billable code used to indicate a diagnosis of other specified mononeuropathies of left lower limb.

Key Diagnostic Point:

G57.82 refers to other specified mononeuropathies affecting the left lower limb, which can arise from various causes including trauma, compression, or systemic diseases. Mononeuropathies are characterized by damage to a single nerve or a group of nerves, leading to symptoms such as pain, weakness, and sensory disturbances in the affected area. In the left lower limb, common causes may include entrapment syndromes like peroneal nerve entrapment, diabetic neuropathy, or post-surgical complications. Clinicians often utilize nerve conduction studies (NCS) to assess the electrical activity of the nerves and confirm the diagnosis. These studies help differentiate between various types of neuropathies and guide treatment options. Accurate coding requires a thorough understanding of the patient's clinical history, symptoms, and diagnostic findings to ensure appropriate management and reimbursement.

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of mononeuropathies, improving the accuracy of diagnoses and treatment plans. G57.82 provides a clear classification for specific conditions affecting the left lower limb, which aids in better patient management and reimbursement processes.

ICD-9 vs ICD-10

Frequently Asked Questions

What are the common causes of G57.82?

Common causes include nerve entrapment syndromes, trauma, systemic diseases like diabetes, and post-surgical complications.

How do nerve conduction studies relate to G57.82?

Nerve conduction studies are essential for diagnosing mononeuropathies, as they assess the electrical activity of the affected nerves and help confirm the diagnosis.
