ICD-11 code 1G01.1 refers to nasopharyngeal myiasis, a medical condition where a person’s nasal cavity and upper throat become infested with larvae of flies. This rare parasitic infection typically occurs in tropical and subtropical regions where poor hygiene and close contact with flies are more common. The condition can lead to symptoms such as nasal discharge, blockage, and severe discomfort.
Nasopharyngeal myiasis is caused by the infestation of fly larvae in the nasal passages and throat. The larvae feed on living or dead tissues, causing irritation, inflammation, and potentially serious complications if left untreated. The condition is usually diagnosed based on clinical symptoms, along with the observation of larvae in the affected areas.
Treatment for nasopharyngeal myiasis may involve removing the larvae from the nasal passages and throat through medical procedures or medications. Preventative measures, such as maintaining good personal hygiene and protecting against fly exposure, can help reduce the risk of developing this parasitic infection. Seeking prompt medical attention is crucial for managing nasopharyngeal myiasis and preventing potential complications.

#️⃣ Coding Considerations
The equivalent SNOMED CT code for ICD-11 code 1G01.1, which represents Nasopharyngeal myiasis, is 233652008. This code is used to classify cases of infestation of the nasopharynx by fly larvae. SNOMED CT is a comprehensive clinical terminology system that provides a standardized way to represent and share health information across different healthcare settings. By using SNOMED CT codes, healthcare providers can ensure accurate and consistent documentation of patient diagnoses, treatments, and outcomes. This helps to improve communication among healthcare professionals, reduce errors, and support better decision-making for patient care. Nasopharyngeal myiasis is a rare condition that requires prompt and appropriate medical intervention to prevent complications and ensure the well-being of the affected individual.
In the United States, ICD-11 is not yet in use. The U.S. is currently using ICD-10-CM (Clinical Modification), which has been adapted from the WHO’s ICD-10 to better suit the American healthcare system’s requirements for billing and clinical purposes. The Centers for Medicare and Medicaid Services (CMS) have not yet set a specific date for the transition to ICD-11.
The situation in Europe varies by country. Some European nations are considering the adoption of ICD-11 or are in various stages of planning and pilot studies. However, as with the U.S., full implementation may take several years due to similar requirements for system updates and training.
🔎 Symptoms
Symptoms of 1G01.1, also known as Nasopharyngeal myiasis, include patients complaining of nasal congestion, irritation, and a foul smell emanating from the nose. These symptoms may be accompanied by the sensation of movement inside the nose, as well as nosebleeds in more severe cases. Patients with Nasopharyngeal myiasis may also experience difficulty breathing and swallowing, as well as a feeling of pressure or fullness in the nasal passages.
Other symptoms of Nasopharyngeal myiasis can include coughing, sneezing, and persistent headaches. Patients may also exhibit signs of local tissue inflammation, such as redness, swelling, and tenderness in the nasal passages. In some cases, patients may develop a fever or experience general malaise as a result of the infestation. The presence of maggots in the nose may also lead to the discharge of pus or bloody secretions.
In advanced cases of Nasopharyngeal myiasis, patients may exhibit symptoms such as facial swelling, vision disturbances, and neurological deficits. The infestation of maggots in the nasal passages can cause severe damage to the surrounding tissues, leading to necrosis and potential complications such as meningitis or encephalitis. In rare instances, Nasopharyngeal myiasis may result in life-threatening conditions if left untreated. Therefore, prompt medical attention is crucial for the management of this parasitic infestation.
🩺 Diagnosis
Diagnosis methods for 1G01.1 (Nasopharyngeal myiasis) typically involve a thorough physical examination of the patient’s nasal cavity and surrounding areas by a healthcare provider. The most common symptoms of nasal myiasis include a feeling of stuffiness or pressure in the nose, nasal discharge, and sometimes even visual observation of maggots in the nasal cavity.
In addition to a physical examination, healthcare providers may order imaging tests such as a CT scan or MRI to further evaluate the extent of the infestation and identify any potential complications. These imaging tests can help determine the presence of maggots, the severity of tissue damage, and the extent of any secondary infections that may have developed as a result of the infestation.
Further diagnostic evaluation may involve taking a sample of nasal secretions or tissue for laboratory analysis. This can help confirm the presence of maggots in the nasal cavity, identify the species of fly responsible for the infestation, and determine the appropriate course of treatment. In some cases, diagnostic procedures may also include endoscopic examination of the nasal cavity to directly visualize the infestation and assess the extent of tissue damage.
💊 Treatment & Recovery
Treatment and recovery methods for Nasopharyngeal myiasis, also known as nasal myiasis, typically involve the removal of the maggots from the nasal cavity. This can be accomplished using several techniques, including manual extraction with forceps or suction devices. Sedation or anesthesia may be necessary to reduce discomfort during this procedure, particularly if the infestation is severe.
In cases where the maggots have caused damage or infection in the nasal cavity, the use of topical or systemic antibiotics may be required to prevent further complications. This can help reduce inflammation and promote healing of any wounds caused by the maggots. In some instances, surgical intervention may be necessary to repair any structural damage that has occurred.
Following treatment for Nasopharyngeal myiasis, patients may require ongoing monitoring to ensure that the infestation has been completely eradicated and to watch for any signs of recurrence. Regular check-ups with a healthcare provider may be recommended to assess healing progress and address any lingering symptoms. Additionally, patients may benefit from counseling or support services to cope with the psychological impact of the infestation and any associated trauma.
🌎 Prevalence & Risk
In the United States, Nasopharyngeal myiasis (1G01.1) is considered to be a rare condition. Cases of myiasis in general are infrequently reported in the country, and nasopharyngeal myiasis specifically is even less common. The exact prevalence of 1G01.1 in the United States is not well-documented, but it is generally believed to be very low.
In Europe, the prevalence of Nasopharyngeal myiasis (1G01.1) is also quite low. Cases of myiasis are more commonly reported in certain regions of Europe where environmental conditions are conducive to the infestation of fly larvae. However, even in these areas, nasopharyngeal myiasis is still considered to be a rare occurrence.
