ICD-10: M79.2

ICD-10 code M79.2 refers to "Neuralgia and neuritis, unspecified." This classification is part of the International Classification of Diseases, 10th Revision (ICD-10), which is used globally for the diagnosis and classification of diseases and health conditions.

Clinical Description

Definition

Neuralgia is characterized by sharp, shooting pain along the path of a nerve, while neuritis refers to inflammation of a nerve. The term "unspecified" indicates that the specific type or cause of the neuralgia or neuritis has not been clearly identified or documented. This can occur in various contexts, including post-injury, post-infection, or idiopathic cases where the origin of the pain is unknown.

Symptoms

Patients with neuralgia and neuritis may experience:
- Severe pain: Often described as sharp, stabbing, or burning, which can be intermittent or constant.
- Sensitivity: Increased sensitivity in the affected area, where even light touch can provoke pain.
- Numbness or tingling: Some patients may report sensations of numbness or tingling in the affected region.
- Weakness: In some cases, there may be associated weakness in the muscles supplied by the affected nerve.

Common Causes

While the code M79.2 is used when the specific cause is not identified, common underlying conditions that can lead to neuralgia and neuritis include:
- Infections: Such as herpes zoster (shingles) or other viral infections.
- Diabetes: Diabetic neuropathy can lead to nerve damage and pain.
- Trauma: Physical injury to a nerve can result in neuritis.
- Autoimmune diseases: Conditions like multiple sclerosis can cause nerve inflammation.

Diagnosis

Diagnosis typically involves a thorough clinical evaluation, including:
- Patient history: Understanding the onset, duration, and characteristics of the pain.
- Physical examination: Assessing the affected area for signs of nerve damage or inflammation.
- Diagnostic tests: Imaging studies (like MRI or CT scans) and nerve conduction studies may be utilized to rule out other conditions.
