B87 refers to Myiasis, a category of parasitic infestations that affect the skin, hair, or body through the presence of lice, mites, fly larvae, or other organisms. These conditions can lead to intense itching, skin damage, and secondary infections. Proper ICD10 coding ensures accurate diagnosis, timely treatment, and supports public health tracking, especially in densely populated or vulnerable communities.

Symptoms

Itching – Persistent and intense, especially at night (e.g., in scabies)
Visible parasites – Lice or larvae may be seen on skin or hair
Red bumps or sores – From bites or burrowing of mites or insects
Secondary infections – Due to scratching and skin damage
Rash or scaling – Especially around infested areas
Inflammation – Swelling or localized irritation
Unpleasant odor – In advanced cases of skin infestation or myiasis

Diagnosis

Diagnosis of Myiasis is primarily clinical, based on physical examination and patient symptoms. Dermoscopy, skin scrapings, or examination under magnification may help identify parasites or their eggs. In the case of myiasis, imaging or surgical exploration may be required to assess larval invasion beneath the skin.

ICD10 Code Usage

ICD10 code B87 is used in clinical documentation, insurance billing, and public health surveillance. It allows for standardized identification and treatment of ectoparasitic infestations. Accurate coding ensures patients receive appropriate care and supports efforts to control infestations in schools, shelters, and long-term care settings.

A: It refers to Myiasis, a parasitic skin or body infestation classified in the ICD10 system for medical documentation and billing.

Q2: Are these conditions contagious?
A: Yes, most are easily spread through close contact, shared clothing, or bedding.

Q3: How are these treated?
A: Treatments include topical insecticides, oral antiparasitics, hygiene measures, and in some cases, manual removal of larvae or parasites.

Q4: Who is at risk?
A: Children, the elderly, those in crowded living conditions, and people with limited access to hygiene are most at risk.

Q5: Can infestations cause complications?
A: Yes, prolonged infestations may lead to skin infections, inflammation, or even systemic symptoms if untreated.

Conclusion

ICD10 code B87 is essential for accurately documenting and managing Myiasis. It supports proper treatment, outbreak control, and healthcare planning, especially in at-risk populations. Consistent use of this code improves care outcomes and public health responses to parasitic infestations.
