D78: ICD10 Code for Intraoperative and postprocedural complications of the spleen
D78 is the ICD10 code used for documenting Intraoperative and postprocedural complications of the spleen in clinical and billing records.

D78 refers to Intraoperative and postprocedural complications of the spleen, 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 Intraoperative and postprocedural complications of the spleen 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 D78 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.

- D80 – Immunodeficiency with predominantly antibody defects
- D81 – Combined immunodeficiencies
- D82 – Immunodeficiency associated with other major defects
- D83 – Common variable immunodeficiency
- D84 – Other immunodeficiencies
- D86 – Sarcoidosis
- D89 – Other disorders involving the immune mechanism, not elsewhere classified
FAQs
Q1: What is ICD10 code D78?
A: It documents Intraoperative and postprocedural complications of the spleen, 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 D78 is essential for identifying and managing Intraoperative and postprocedural complications of the spleen. These codes support timely treatment, help in preventing complications, and allow for consistent tracking in patients with immune system dysfunctions or surgical complications.
