• Infection by Coccidioides immitis
• Pneumonia with coccidioidomycosis
• Pneumonia with coccidioidomycosis
• Pulmonary coccidioidomycosis
• Pulmonary coccidioidomycosis

Clinical Information

• Coccidioidomycosis

  infection with a fungus of the genus coccidioides, endemic to the southwestern united states. it is sometimes called valley fever but should not be confused with rift valley fever. infection is caused by inhalation of airborne, fungal particles known as arthroconidia, a form of fungal spores. a primary form is an acute, benign, self-limited respiratory infection. a secondary form is a virulent, severe, chronic, progressive granulomatous disease with systemic involvement. it can be detected by use of coccidioidin.

B38.1 is grouped with Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together diagnosis codes for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on their principal diagnosis in areas referred to as Major Diagnostic Categories (MDC). Once a patient is assigned a particular diagnostic category, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care for that patient. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V41.0 applicable from 10/01/2023 through 09/30/2024.

MS-DRG	MS-DRG Title	MCD	Relative Weight
177	RESPIRATORY INFECTIONS AND INFLAMMATIONS WITH MCC	04	1.6964
178	RESPIRATORY INFECTIONS AND INFLAMMATIONS WITH CC	04	0.9867
179	RESPIRATORY INFECTIONS AND INFLAMMATIONS WITHOUT CC/MCC	04	0.7633

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

Patient Education

Valley Fever

Valley Fever is a disease caused by a fungus (or mold) called Coccidioides. The fungi live in the soil of dry areas like the southwestern U.S. You get it from inhaling the spores of the fungus. The infection cannot spread from person to person.

Anyone can get Valley Fever. But it's most common among older adults, especially those 60 and older. People who have recently moved to an area where it occurs are at highest risk for infection. Other people at higher risk include:

• Workers in jobs that expose them to soil dust. These include construction workers, agricultural workers, and military forces doing field training.
• African Americans and Asians
• Women in their third trimester of pregnancy
• People with weak immune systems

Valley Fever is often mild, with no symptoms. If you have symptoms, they may include a flu-like illness, with fever, cough, headache, rash, and muscle aches. Most people get better within several weeks or months. A small number of people may develop a chronic lung or widespread infection.

Valley Fever is diagnosed by testing your blood, other body fluids, or tissues. Many people with the acute infection get better without treatment. In some cases, doctors may prescribe antifungal drugs for acute infections. Severe infections require antifungal drugs.
