D84: Other immunodeficiencies

D84 refers to Other immunodeficiencies, a category of immune system disorders and procedural complications that affect the body's ability to defend against infections or result from surgical events. These conditions range from genetic immunodeficiencies to immune dysregulation syndromes and post-surgical spleen damage.

Symptoms

• Recurrent infections – Especially respiratory, gastrointestinal, and sinus infections
• Delayed wound healing – From immune impairment
• Unexplained fever or inflammation – Especially in sarcoidosis or immune dysregulation
• Post-surgical bleeding or abscess – For D78 complications
• Autoimmune manifestations – Seen in combined or variable immunodeficiencies
• Lymphadenopathy – Especially in sarcoidosis or chronic immunologic disease
• Fatigue or weakness – From chronic immune dysfunction

Diagnosis

Diagnosis of Other immunodeficiencies involves immunoglobulin level testing, flow cytometry, lymphocyte function assays, biopsy (e.g., for sarcoidosis), and imaging for surgical complications. A multidisciplinary approach is often required including immunology, infectious disease, and surgery.

ICD10 Code Usage

ICD10 code D84 is used in immunology, internal medicine, surgery, and oncology to document immune system dysfunctions and spleen-related procedural events. These codes are essential for accurate clinical tracking, immunotherapy eligibility, and billing documentation.

Related Codes

• D78 – Intraoperative and postprocedural complications of the spleen
• D80 – Immunodeficiency with predominantly antibody defects
• D81 – Combined immunodeficiencies
• D82 – Immunodeficiency associated with other major defects
• D83 – Common variable immunodeficiency
• D86 – Sarcoidosis
• D89 – Other disorders involving the immune mechanism, not elsewhere classified

FAQs

Q1: What is ICD10 code D84?
A: It documents Other immunodeficiencies, covering complications of the spleen and primary or acquired immune disorders.

Q2: Are these chronic conditions?
A: Many immune disorders are lifelong, though their severity and treatment options vary greatly.

Q3: What causes immune deficiencies?
A: Genetic mutations, environmental exposures, certain medications, or underlying health conditions.

Q4: How are these disorders managed?
A: Immunoglobulin replacement, infection prophylaxis, immunosuppressants, surgery, and supportive care.

Q5: Who typically manages care?
A: Clinical immunologists, hematologists, infectious disease experts, and surgeons for procedural issues.

Conclusion

ICD10 code D84 is essential for identifying and managing Other immunodeficiencies. These codes support timely treatment, help in preventing complications, and allow for consistent tracking in patients with immune system dysfunctions or surgical complications.
