ICD-11 code 1G04.1 refers to Crusted scabies, a severe form of scabies, which is a contagious skin infestation caused by the mite Sarcoptes scabiei.
Crusted scabies, also known as Norwegian scabies, is characterized by an extensive rash with thick crusts of skin containing large numbers of mites and eggs.
This form of scabies is more common in individuals with weakened immune systems, such as those with HIV/AIDS or elderly individuals, and can lead to complications such as bacterial skin infections if left untreated.

#️⃣ Coding Considerations
The SNOMED CT code equivalent to the ICD-11 code 1G04.1 for crusted scabies is 86406008. This code specifically identifies the same condition in the SNOMED CT terminology system, allowing for seamless communication and interoperability in healthcare settings. Crusted scabies, also known as Norwegian scabies, is a severe form of scabies caused by the same mite but with a much higher number of mites present. The SNOMED CT code ensures that healthcare professionals can accurately document and track cases of crusted scabies, leading to improved patient care and outcomes. By utilizing standardized codes like 86406008, medical professionals can easily access and share information about this challenging skin condition.
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 1G04.1, also known as Crusted Scabies, primarily involve severe and persistent itching of the skin. This itching is often more intense at night and can lead to insomnia and irritability. In addition to itching, other common symptoms include thick crusts or scales on the skin, particularly on the hands, feet, and nails.
Crusted scabies can also cause skin lesions that may appear as red, inflamed patches or raised bumps. These lesions can be intensely itchy and may become irritated with scratching, leading to the formation of open sores or ulcers. In severe cases, crusted scabies can also lead to secondary bacterial infections, characterized by increased redness, warmth, and pus at the site of the infection.
Individuals with crusted scabies may experience a thickening of the skin, known as hyperkeratosis, especially on the palms of the hands and soles of the feet. This thickening can contribute to the formation of crusts or scales, making them more difficult to remove. In some cases, crusted scabies can also cause nail deformities, such as thickening, discoloration, or crumbling of the nails. These symptoms may persist even after treatment for scabies has been administered.
🩺 Diagnosis
Diagnosing 1G04.1 (Crusted scabies) typically begins with a physical examination by a healthcare provider. The characteristic thick, crusted lesions on the skin are often a telltale sign of this condition. The provider may also use a handheld magnifying lens called a dermatoscope to closely examine the affected areas for signs of mites or their eggs.
In order to confirm the diagnosis of 1G04.1, a skin scraping or biopsy may be performed. During a skin scraping, the healthcare provider will gently scrape off a small sample of skin from the affected area. This sample is then examined under a microscope for the presence of mites, eggs, or fecal matter – all of which are indicative of scabies infestation.
In some cases, a dermatologist may conduct a technique known as dermoscopy to aid in the diagnosis of 1G04.1. Dermoscopy involves using a specialized tool called a dermatoscope to examine the skin at a higher magnification. This can help the provider visualize the burrows and tunnels created by the scabies mites, further confirming the diagnosis.
💊 Treatment & Recovery
Treatment for Crusted scabies, also known as hyperkeratotic scabies, typically involves a combination of topical medications and oral medications. Topical treatments such as permethrin cream or benzyl benzoate lotion are commonly used to kill the mites and their eggs. These medications are applied to the entire body and left on for a specific amount of time before being washed off.
In addition to topical treatments, oral medications such as ivermectin may be prescribed to help eliminate the infestation. Ivermectin is taken in a series of doses over a period of time, and may be used in conjunction with topical treatments for maximum effectiveness. It is important to follow the prescribed treatment regimen closely to ensure successful eradication of the mites.
After undergoing treatment for Crusted scabies, it is important for individuals to follow up with their healthcare provider to monitor their progress and ensure that the mites have been successfully eliminated. It may take several weeks for symptoms to completely resolve, and additional treatments may be necessary to fully eradicate the infestation. Proper hygiene practices, such as washing bedding and clothing in hot water and vacuuming carpets and furniture, can also help prevent reinfestation.
🌎 Prevalence & Risk
In the United States, the prevalence of 1G04.1 (Crusted scabies) is relatively low compared to other regions. This severe form of scabies is more commonly seen in vulnerable populations such as individuals with compromised immune systems, institutionalized individuals, and people living in overcrowded or unsanitary conditions. The exact prevalence of crusted scabies in the United States is difficult to determine due to underreporting and lack of specific data collection on this specific type of scabies.
In Europe, the prevalence of 1G04.1 (Crusted scabies) is higher compared to the United States. This may be due to a higher number of cases reported in institutional settings such as hospitals, nursing homes, and homeless shelters. Crusted scabies is more commonly seen in Europe among individuals with preexisting health conditions that weaken the immune system, making them more susceptible to severe infestations of scabies mites. Despite efforts to control and prevent the spread of scabies, crusted scabies remains a significant public health concern in some European countries.
In Asia, the prevalence of 1G04.1 (Crusted scabies) is notably higher compared to the United States and Europe. This region has a higher population density, which can contribute to the spread of scabies mites and the development of crusted scabies. Additionally, limited access to healthcare and poor living conditions in some parts of Asia can exacerbate the prevalence of crusted scabies among vulnerable populations. Efforts to control and prevent the spread of scabies in Asia are ongoing, but challenges such as lack of awareness, stigma, and limited resources can hinder progress in addressing this public health issue.
In Africa, the prevalence of 1G04.1 (Crusted scabies) is significant, particularly in regions with poor living conditions and limited access to healthcare. Crusted scabies is more commonly seen in vulnerable populations such as individuals with compromised immune systems, institutionalized individuals, and people living in overcrowded or unsanitary conditions. The exact prevalence of crusted scabies in Africa is difficult to determine due to underreporting and lack of specific data collection on this severe form of scabies. Efforts to control and prevent the spread of scabies in Africa are ongoing, but challenges such as lack of resources, infrastructure, and awareness can hinder progress in addressing this public health issue.
😷 Prevention
To prevent 1G04.1 (Crusted scabies), also known as Norwegian scabies, it is important to practice good hygiene and maintain a clean living environment. Regularly washing your hands with soap and water can help prevent the spread of scabies mites, which are responsible for causing this condition. Additionally, avoiding close contact with individuals who have crusted scabies can help reduce the risk of transmission.
Furthermore, managing outbreaks of scabies in institutional settings, such as nursing homes or prisons, is essential for preventing the spread of 1G04.1. This may involve implementing strict infection control measures, such as isolating affected individuals and providing appropriate treatment to prevent further transmission. Regularly inspecting and treating bedding and clothing in these settings can also help prevent the spread of crusted scabies.
In addition to these measures, individuals with weakened immune systems, such as those with HIV/AIDS or undergoing chemotherapy, should take extra precautions to prevent 1G04.1. This may include avoiding contact with individuals who have scabies, practicing good personal hygiene, and seeking prompt medical attention if symptoms of crusted scabies develop. By following these preventive measures, the risk of contracting and spreading 1G04.1 can be significantly reduced.
🦠 Similar Diseases
1G04.1 (Crusted scabies) is a specific code used to classify a severe form of scabies caused by the infestation of the skin by the Sarcoptes scabiei mite. Similar diseases include other forms of scabies such as typical scabies, nodular scabies, and bullous scabies.
Scabies, which is caused by the same mite, typically presents with intense itching and a rash characterized by small bumps or blisters. Nodular scabies is a variant in which the skin becomes thickened and nodular due to a hypersensitivity reaction to the mite. Bullous scabies involves the formation of fluid-filled blisters on the skin, which can be mistaken for other skin conditions such as dermatitis.
In addition to scabies, other parasitic infestations such as pediculosis (lice infestation) and tungiasis (sand flea infestation) can produce similar symptoms to crusted scabies. Pediculosis is characterized by the presence of lice eggs (nits) attached to the hair shafts, while tungiasis involves the burrowing of sand fleas into the skin, leading to painful nodules and swelling. These parasitic infestations require specific treatment measures to eradicate the infestation and alleviate symptoms.
