Disorders of other cranial nerves (G52)

The ICD-10 code section G52 covers disorders of various cranial nerves beyond the most commonly coded ones, such as the olfactory, glossopharyngeal, vagus, hypoglossal, and accessory nerves. These codes are used when diagnosing or documenting nerve dysfunction, damage, or neuropathies affecting these specific cranial nerves.

This section includes codes like G52.0 for olfactory nerve disorders, which relate to issues such as compression or dysfunction of the nerve responsible for smell. G52.1 refers to disorders of the glossopharyngeal nerve, encompassing symptoms like throat pain or neuralgia and conditions known by terms like glossopharyngeal neuralgia or ninth cranial nerve findings. G52.2 covers vagus nerve disorders, including vocal cord paralysis and sensory disturbances, while G52.3 involves hypoglossal nerve problems often linked to tongue motor issues. Additionally, G52.7 and G52.8 handle multiple or other specified cranial nerve disorders, with synonyms including jugular foramen syndrome or accessory nerve palsy. The unspecified code G52.9 captures generalized cranial nerve disorders when specific nerves are not detailed. Using the ICD-10 code for [condition] from this group helps medical professionals accurately classify nerve-related diagnoses for effective treatment and documentation.
