ICD10 code of Melkersson-Rosenthal Syndrome and ICD9 code

Melkersson-Rosenthal Syndrome is classified under the ICD-10 code G51.2 and the ICD-9 code 351.8. These diagnostic codes are essential for healthcare providers to document the condition, which is a rare neurological disorder characterized by recurring facial paralysis, swelling of the face and lips, and a fissured tongue.

What are the diagnostic codes for Melkersson-Rosenthal Syndrome?

In the International Classification of Diseases, 10th Revision (ICD-10), Melkersson-Rosenthal Syndrome is specifically assigned the code G51.2. In the older ICD-9 system, which is still referenced in some historical medical records and legacy billing systems, the syndrome is categorized under code 351.8, representing "other facial nerve disorders." Accurate coding is vital for patients seeking insurance coverage for specialized treatments and for researchers tracking the prevalence of Melkersson-Rosenthal Syndrome within global health databases.

What are the clinical signs of Melkersson-Rosenthal Syndrome?

Melkersson-Rosenthal Syndrome is classically defined by a triad of symptoms, though it is important to note that many patients experience only a "monosymptomatic" or "oligosymptomatic" form, meaning they do not always manifest all three signs simultaneously. These symptoms include:

• Recurrent orofacial edema: Persistent or intermittent swelling of the lips (cheilitis granulomatosa) or other parts of the face.


• Peripheral facial nerve palsy: Often unilateral, this paralysis can be temporary or recurrent.


• Lingua plicata: A fissured or "cracked" appearance of the tongue, which is often a congenital or early-onset feature.

How is Melkersson-Rosenthal Syndrome diagnosed?

Diagnosing Melkersson-Rosenthal Syndrome is often a process of exclusion, as there is no single blood test or genetic marker that confirms the condition. Physicians typically rely on a combination of clinical physical examinations and biopsy results. A biopsy of the swollen lip tissue often reveals non-caseating granulomas, which help differentiate Melkersson-Rosenthal Syndrome from other inflammatory conditions like Crohn’s disease or sarcoidosis. Because it is a rare disorder, patients often experience a "diagnostic odyssey," highlighting the importance of consulting with neurologists or dermatologists who have specific experience with this rare entity.

Is there support for those living with Melkersson-Rosenthal Syndrome?

Living with a visible and often unpredictable condition can be challenging. At DiseaseMaps.org, we have seen a growing community of 73 people with Melkersson-Rosenthal Syndrome who share their personal experiences, symptom management strategies, and emotional support. Connecting with others who understand the frustration of facial swelling and nerve issues can significantly improve your quality of life. The psychological impact of living with a chronic, rare condition is significant, and finding a supportive peer group is a key step in navigating the Melkersson-Rosenthal Syndrome journey.

Next steps

• Consult a neurologist or a dermatologist specializing in oral medicine to confirm your diagnosis and rule out systemic associations.


• Keep a detailed symptom diary to track the frequency and duration of facial swelling episodes for your specialist.


• Join the DiseaseMaps.org community to connect with other patients and share resources.


• Ask your physician about anti-inflammatory treatments or corticosteroid therapies, which are frequently used to manage acute swelling.
