2024 ICD-10-CM Diagnosis Code B57.1

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

• Acute Chagas' disease
• Acute Chagas disease without heart involvement
• Chagoma
• Trypanosomiasis affecting skin

B57.1 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
867	OTHER INFECTIOUS AND PARASITIC DISEASES DIAGNOSES WITH MCC	18	2.0923
868	OTHER INFECTIOUS AND PARASITIC DISEASES DIAGNOSES WITH CC	18	1.0855
869	OTHER INFECTIOUS AND PARASITIC DISEASES DIAGNOSES WITHOUT CC/MCC	18	0.6907

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.

Convert B57.1 to ICD-9-CM

• ICD-9-CM Code: 086.2 - Chagas disease NOS
  Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Chagas Disease

What is Chagas disease?

Chagas disease, or American trypanosomiasis, is an illness that can cause serious heart and stomach problems. It is caused by a parasite. Chagas disease is common in Latin America, especially in poor, rural areas. It can also be found in the United States, most often in people who were infected before they moved to the U.S.

What causes Chagas disease?

Chagas disease is caused by the Trypanosoma cruzi parasite. It is usually spread by infected blood-sucking bugs called triatomine bugs. They are also known as "kissing bugs" because they often bite people's faces. When one of these bugs bites you, it leaves behind infected waste. You can become infected if you rub the waste in your eyes or nose, the bite wound, or a cut.

Chagas disease can also spread through contaminated food, a blood transfusion, a donated organ, or from the pregnant parent to the baby during pregnancy.

Who is more likely to develop Chagas disease?

Kissing bugs can be found throughout the Americas, but they are more common in certain areas. The people who are most at risk for Chagas disease:

• Live in rural areas of Latin America
• Have seen the bugs, especially in those areas
• Have stayed in a house with a thatched roof or with walls that have cracks or crevices

What are the symptoms of Chagas disease?

In the beginning, there may be no symptoms. Some people do get mild symptoms, such as:

• Fever
• Fatigue
• Body aches
• Headache
• Loss of appetite
• Diarrhea
• Vomiting
• A rash
• A swollen eyelid

These early symptoms usually go away. However, if you don't treat the infection, it stays in your body. Later, it can cause serious intestinal and heart problems such as:

• An serious arrhythmia (a problem with the rate or rhythm of your heartbeat) that can cause sudden death
• An enlarged heart that doesn't pump blood well
• Problems with digestion and bowel movements
• An increased chance of having a stroke

How is Chagas disease diagnosed?

To find out if you have Chagas disease, your health care provider:

• Will do a physical exam
• Will take your medical history, including asking about your symptoms and where you have lived and traveled
• Will run a blood test for Chagas disease
• May run tests to see whether the disease has affected your intestines and heart

What are the treatments for Chagas disease?

Medicines can kill the parasite, especially early on. You can also treat related problems. For example, a pacemaker can help with some heart complications.

Can Chagas disease be prevented?

There are no vaccines or medicines to prevent Chagas disease. If you travel to areas where it occurs, you are at higher risk if you sleep outdoors or are staying in poor housing conditions. It is important to use insecticides to prevent bites and practice food safety.
