ICD-10: D84.82

ICD-10 code D84.82 refers to "Immunodeficiency due to drugs and external causes." This classification is part of the broader category of immunodeficiencies, which are conditions that impair the immune system's ability to function effectively. Below is a detailed overview of this code, including its clinical description, causes, and implications.

Clinical Description

Definition

D84.82 specifically denotes immunodeficiency that arises as a result of pharmacological agents or external factors. This can include a range of drugs that suppress the immune system, either intentionally (as in the case of immunosuppressive therapy for autoimmune diseases or organ transplants) or unintentionally (as a side effect of other medications).

Symptoms and Manifestations

Patients with immunodeficiency due to drugs and external causes may present with:
- Increased susceptibility to infections, including bacterial, viral, and fungal infections.
- Recurrent infections that may be more severe or prolonged than typical.
- Delayed wound healing.
- Possible development of opportunistic infections, which are infections that occur more frequently and are more severe in individuals with weakened immune systems.

Diagnosis

Diagnosis of D84.82 typically involves:
- A thorough medical history to identify any medications or external factors that may have contributed to the immunodeficiency.
- Laboratory tests to assess immune function, including complete blood counts and specific immune response tests.
- Evaluation of clinical symptoms and history of recurrent infections.

Causes

Drug-Induced Immunodeficiency

Several classes of drugs can lead to immunodeficiency, including:
- Corticosteroids: Often used to treat inflammatory conditions, these can suppress the immune response.
- Chemotherapy agents: Used in cancer treatment, these drugs can significantly reduce white blood cell counts.
- Immunosuppressants: Medications prescribed to prevent organ rejection in transplant patients or to treat autoimmune diseases.

External Causes

External factors contributing to immunodeficiency may include:
- Radiation exposure: Can damage bone marrow and affect immune cell production.
- Infections: Certain viral infections, such as HIV, can lead to secondary immunodeficiency.
- Nutritional deficiencies: Lack of essential nutrients can impair immune function.

Implications for Treatment

Management Strategies

Management of patients with D84.82 focuses on:
- Identifying and modifying the causative agent: If a specific drug is identified as the cause, adjusting the treatment regimen may be necessary.
