Leptospirosis icterohemorrhagica

Billable Code

| ICD-10 from 2011 - 2016

A27.0 is a billable ICD code used to specify a diagnosis of leptospirosis icterohemorrhagica. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code A27 is used to code Leptospirosis

Leptospirosis (also known as field fever, rat catcher's yellows, and pretibial fever among others names) is an infection caused by corkscrew-shaped bacteria called Leptospira. Signs and symptoms can range from none to mild such as headaches, muscle pains, and fevers; to severe with bleeding from the lungs or meningitis. If the infection causes the person to turn yellow, have kidney failure and bleeding, it is then known as Weil's disease. If it causes lots of bleeding from the lungs it is known as severe pulmonary haemorrhage syndrome.
