Myiasis (B87)
The ICD-10 code B87 covers the diagnosis of myiasis, an infestation caused by fly larvae in various body sites. These codes specify the affected area and type of myiasis, assisting in accurate medical classification and treatment planning.
Myiasis (B87) refers to the infestation by parasitic fly larvae in humans. The codes range from B87.0 for cutaneous myiasis; also known as furuncular myiasis or cutaneous screw-worm myiasis; to specialized forms like B87.1 for wound myiasis and B87.2 for ocular myiasis, including conditions like ophthalmic myiasis or external ocular myiasis. Other site-specific codes include B87.3 for nasopharyngeal myiasis, B87.4 for aural myiasis, and B87.81 for genitourinary myiasis. Intestinal infestation is captured under B87.82. When the site is not specified, B87.9 is used, covering various infestations such as those caused by Dermatobia hominis or Gasterophilus species. These ICD-10 codes enable healthcare providers to document precise clinical details for parasitic infestations by fly larvae, facilitating effective diagnosis and intervention.
