2024 ICD-10-CM Diagnosis Code B74.9

Approximate Synonyms

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

• Disease due to superfamily Filarioidea
• Filarial abscess
• Filarial infection of conjunctiva
• Lymphatic filariasis
• Parasitic conjunctivitis
• Pulmonary filariasis
• Pulmonary nematodiasis
• Serous cavity filariasis
• Subcutaneous filariasis

Clinical Information

• Elephantiasis, Filarial

  parasitic infestation of the human lymphatic system by wuchereria bancrofti or brugia malayi. it is also called lymphatic filariasis.

• Filariasis

  infections with nematodes of the superfamily filarioidea. the presence of living worms in the body is mainly asymptomatic but the death of adult worms leads to granulomatous inflammation and permanent fibrosis. organisms of the genus elaeophora infect wild elk and domestic sheep causing ischemic necrosis of the brain, blindness, and dermatosis of the face.

• Loiasis

  a parasitic infection caused by the nematode loa loa. the vector in the transmission of this infection is the horsefly (tabanus) or the deerfly or mango fly (chrysops). the larvae may be seen just beneath the skin or passing through the conjunctiva. eye lesions are not uncommon. the disease is generally mild and painless.

• Filarioidea

  a superfamily of nematodes of the order spirurida. members possess a filiform body and a mouth surrounded by papillae.

• Filariasis

  infection by filarial worms.

• Lymphatic Filariasis|Elephantiasis

  a clinical disorder that is caused by obstruction of the lymphatic system years after filarial infection. it is characterized by painful and profound lymphedema, resulting in significant swelling (elephantiasis) of extremities and genitals.

B74.9 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.

Patient Education

Parasitic Diseases

Parasites are living things that use other living things - like your body - for food and a place to live. You can get them from contaminated food or water, a bug bite, or sexual contact. Some parasitic diseases are easily treated and some are not.

Parasites range in size from tiny, one-celled organisms called protozoa to worms that can be seen with the naked eye. Some parasitic diseases occur in the United States. Contaminated water supplies can lead to Giardia infections. Cats can transmit toxoplasmosis, which is dangerous for pregnant women. Others, like malaria, are common in other parts of the world.

If you are traveling, it's important to drink only water you know is safe. Prevention is especially important. There are no vaccines for parasitic diseases. Some medicines are available to treat parasitic infections.
