ICD-11 code 1G03, also known as Pthiriasis, is a specific code used in the International Classification of Diseases to classify and identify diseases. Pthiriasis, commonly known as “crab lice infestation,” refers to an infestation of parasitic insects called pubic lice. These insects typically infest the pubic hair but can also be found in other areas with coarse hair, such as the armpits, chest, and eyelashes.
The symptoms of Pthiriasis may include itching in the affected areas, visible lice or eggs attached to the hair shafts, and skin irritation or inflammation from scratching. Pthiriasis is usually transmitted through close personal contact with an infected individual, such as through sexual activity. It is important to seek treatment for Pthiriasis to eliminate the infestation and prevent the spread of the parasites to others. Treatment options may include medicated shampoos or lotions, as well as measures to remove and kill the lice and eggs from the affected areas.

#️⃣ Coding Considerations
SNOMED CT code 46930008 corresponds to the ICD-11 code 1G03, which covers the condition known as Pthiriasis. Pthiriasis is a medical term for an infestation of lice, specifically the pubic louse. These parasitic insects lay their eggs in the hair, leading to itching and irritation in the affected area. Pthiriasis is typically transmitted through close physical contact with an infected individual. Treatment options for Pthiriasis include medicated shampoos, creams, and lotions that are designed to eliminate the lice and their eggs. It is important to seek medical attention if you suspect you have Pthiriasis, as it can be easily transmitted to others through close contact.
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 1G03, also known as Pthiriasis, typically include severe itching in the affected area. This intense itching is caused by the presence of pubic lice, which are tiny parasites that feed on human blood. These lice can be found in the genital area as well as in other coarse hair, such as the armpits, chest, and even eyelashes.
In addition to itching, individuals with Pthiriasis may also experience redness and inflammation of the skin in the affected area. This can lead to the development of small red or blue spots on the skin, which may be a result of the louse bites. Scratching the irritated skin can further exacerbate the inflammation and potentially lead to secondary infections.
Some individuals with Pthiriasis may also notice the presence of small white eggs or lice in their pubic hair. These eggs, known as nits, are often attached to the hair shafts and can be a sign of an active infestation. Identifying nits or live lice in the affected area is a key diagnostic feature of Pthiriasis and can help healthcare providers determine the appropriate course of treatment.
🩺 Diagnosis
Diagnosis of 1G03 (Pthiriasis) primarily relies on a thorough physical examination of the affected individual. Healthcare providers will inspect the skin and hair for the presence of pubic lice, also known as Pthirus pubis. These tiny parasites are typically visible to the naked eye and can be found near the base of hair follicles in the genital area.
In addition to a physical exam, healthcare providers may use a magnifying lens or dermatoscope to get a closer look at the pubic lice and their eggs. The eggs, also known as nits, are small white or yellowish dots that cling to the hair shaft near the skin. By identifying both the adult lice and their eggs, healthcare providers can confirm a diagnosis of pthiriasis.
In some cases, healthcare providers may collect a sample of the affected person’s skin or hair to examine under a microscope. This can help confirm the presence of pubic lice and differentiate them from other skin conditions that may present similar symptoms. Additionally, healthcare providers may ask about the individual’s sexual history and recent exposure to pubic lice to further support the diagnosis of 1G03 (Pthiriasis).
💊 Treatment & Recovery
Treatment for Pthiriasis, commonly referred to as pubic lice infestation or “crabs,” typically involves the use of medicated creams or lotions. These products contain chemicals that kill the lice and their eggs. Over-the-counter treatments are available, but prescription-strength options may be necessary for severe cases.
In addition to topical treatments, it is important to thoroughly wash all clothing, bedding, and towels that may have come into contact with the infested area. This helps prevent re-infestation and ensures that the lice are completely eradicated from the environment. Personal items that cannot be washed can be sealed in a plastic bag for a few days to suffocate the lice.
Regularly combing the affected area with a fine-toothed nit comb can also help remove lice and eggs from the hair. This process should be repeated every few days to ensure any newly hatched lice are also removed. It is important to follow all treatment instructions carefully and continue treatment until all signs of infestation have disappeared.
Recovery from Pthiriasis may take time, as it can be difficult to completely eliminate the infestation. It is important to closely monitor the affected area for any signs of re-infestation and continue treatment as needed. In some cases, a healthcare provider may recommend follow-up appointments to ensure the lice have been effectively eradicated. Proper hygiene practices, including regular washing of clothing and bedding, can help prevent future infestations.
🌎 Prevalence & Risk
In the United States, the prevalence of 1G03, commonly known as Pthiriasis or pubic lice infestation, is estimated to be relatively low compared to other countries. Despite efforts to educate the public on prevention and treatment options, cases of Pthiriasis still occur, particularly among certain populations such as individuals living in crowded and unsanitary conditions.
In Europe, the prevalence of Pthiriasis is slightly higher than in the United States, with increased occurrences reported in countries with poor hygiene practices and limited access to healthcare. While the overall rates of infestation have decreased over the years due to improved hygiene habits and the availability of effective treatment options, sporadic outbreaks still occur among certain communities.
In Asia, the prevalence of 1G03 varies significantly across different regions, with higher rates reported in countries with dense populations and inadequate sanitation facilities. Limited access to healthcare services and cultural taboos surrounding discussions of sexually transmitted infections contribute to the underreporting of Pthiriasis cases in some Asian countries. Efforts to raise awareness and promote regular screenings are essential in reducing the prevalence of Pthiriasis in these regions.
In Africa, the prevalence of Pthiriasis is relatively high compared to other continents, particularly in countries with limited resources for public health initiatives. Factors such as poor sanitation, lack of access to healthcare services, and cultural beliefs about personal hygiene contribute to the continued spread of pubic lice infestations in certain African communities. Collaborative efforts between healthcare providers, government agencies, and local communities are necessary to address the underlying factors contributing to the high prevalence of Pthiriasis in Africa.
😷 Prevention
Pthiriasis, commonly known as crab lice infestation, is a parasitic infection caused by the crab or pubic louse. This condition is primarily spread through sexual contact or close bodily contact with an infected individual. To prevent the spread of Pthiriasis, individuals should practice safe sex by using condoms and avoiding intimate contact with individuals who may be infected.
In addition, maintaining good personal hygiene is crucial in preventing the spread of Pthiriasis. Regularly washing clothing, bedding, and towels in hot water and drying them on high heat can help kill any lice or eggs that may be present. Individuals should also avoid sharing personal items such as combs, brushes, and clothing with others to reduce the risk of transmission.
Furthermore, individuals should seek treatment promptly if they suspect they have been infected with crab lice. Medical treatment for Pthiriasis typically includes the use of medicated shampoos or lotions that kill the lice and their eggs. Following the prescribed treatment plan and completing the full course of medication is essential to fully eradicate the infestation and prevent re-infestation. By following these preventive measures, individuals can reduce the risk of contracting and spreading Pthiriasis.
🦠 Similar Diseases
One disease similar to Pthiriasis in terms of its code classification is 1G04, which corresponds to Pediculosis. Pediculosis is an infestation of lice on the skin or hair, typically causing itching and discomfort. Like Pthiriasis, Pediculosis is spread through close physical contact and is often seen in crowded or unsanitary conditions.
Another disease with a comparable code to Pthiriasis is 1G05, indicating Scabies. Scabies is a skin infestation caused by the Sarcoptes scabiei mite, resulting in itching and a rash. Scabies is also transmitted through skin-to-skin contact or by sharing clothing or bedding with an infested individual, similar to the mode of transmission for Pthiriasis.
Additionally, a disease related to Pthiriasis under the same code classification is 1G06, representing Dermatophytosis. Dermatophytosis, commonly known as ringworm, is a fungal infection of the skin that causes a ring-shaped rash with itching and scaling. While the causative agents differ (lice or mites versus fungi), Dermatophytosis shares similarities with Pthiriasis in terms of skin manifestations and potential modes of transmission.
