ICD-10 code A74 title: Rocky Mountain spotted fever
ICD-10 A74 is a billable code used to indicate a diagnosis of icd-10 code a74 title: rocky mountain spotted fever.
Rocky Mountain spotted fever (RMSF) is a tick-borne illness caused by the bacterium Rickettsia rickettsii. It is characterized by fever, headache, and a distinctive rash that typically appears 2-5 days after the onset of fever. The rash often starts as small, flat, pink spots that can progress to petechiae and purpura. RMSF is transmitted primarily through the bite of infected ticks, particularly the American dog tick and the Rocky Mountain wood tick. Early diagnosis and treatment are crucial, as the disease can lead to severe complications, including organ failure and death if left untreated. Diagnosis is often based on clinical presentation and history of tick exposure, with serological tests available to confirm the infection. Treatment typically involves the use of doxycycline, which is effective if administered early in the course of the disease. The condition is more prevalent in certain geographic areas, particularly in the southeastern and south-central United States, and is more common during the warmer months when ticks are active.
