Clinical Information

• Allergic Fungal Sinusitis

  fungal infection in the paranasal sinuses characterized by common allergy respiratory symptoms, recurrent nasal polyps and/or asthma with buildup of allergic mucin.

• Fungemia

  the presence of fungi circulating in the blood. opportunistic fungal sepsis is seen most often in immunosuppressed patients with severe neutropenia or in postoperative patients with intravenous catheters and usually follows prolonged antibiotic therapy.

• Fungal Esophagitis

  infection of the esophagus caused by fungi, most often candida albicans and candida tropicalis. it usually affects patients with immunodeficiency disorders or diabetes mellitus. symptoms include dysphagia and pain on swallowing.

• Fungal Keratitis

  keratitis caused by fungi.

• Acute Pyelonephritis

  sudden onset pyelonephritis.

• Fungal Endophthalmitis

  inflammation of the lining of the ocular cavities, which results from a fungal infection.

• Fungemia

  a laboratory test result indicating the presence of fungi or yeasts in the blood.

• Fungemia, CTCAE|Fungemia

  a disorder characterized by the presence of fungus in the blood stream.

  severe or medically significant but not immediately life-threatening; hospitalization or prolongation of existing hospitalization indicated

B49 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.

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 B49 to ICD-9-CM

• ICD-9-CM Code: 117.9 - Mycoses NEC & 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.

Patient Education

Fungal Infections

If you have ever had athlete's foot or a yeast infection, you can blame a fungus. A fungus is a primitive organism. Mushrooms, mold and mildew are examples. Fungi live in air, in soil, on plants and in water. Some live in the human body. Only about half of all types of fungi are harmful.

Some fungi reproduce through tiny spores in the air. You can inhale the spores or they can land on you. As a result, fungal infections often start in the lungs or on the skin. You are more likely to get a fungal infection if you have a weakened immune system or take antibiotics.

Fungi can be difficult to kill. For skin and nail infections, you can apply medicine directly to the infected area. Oral antifungal medicines are also available for serious infections.
