ICD-10: Z90.81

The ICD-10-CM code Z90.81 refers to the clinical condition known as the acquired absence of the spleen. This condition can arise from various medical interventions or pathological processes that necessitate the removal of the spleen, a procedure known as splenectomy.

Clinical Description

Definition

The acquired absence of the spleen indicates that the spleen has been surgically removed or is absent due to other medical reasons. The spleen plays a crucial role in the immune system, particularly in filtering blood and managing the body's response to infections. Its absence can lead to increased susceptibility to certain infections, particularly those caused by encapsulated bacteria.

Causes

The primary causes of acquired absence of the spleen include:

• Trauma: Severe abdominal injuries may necessitate splenectomy to control bleeding or prevent further complications.
• Diseases: Conditions such as hematological disorders (e.g., hereditary spherocytosis, thalassemia) or certain cancers (e.g., lymphoma) may require the removal of the spleen.
• Infections: Some infections can lead to splenic rupture, necessitating surgical removal.
• Congenital Absence: Although not classified under acquired absence, it is important to note that some individuals may be born without a spleen (asplenia).

Clinical Implications

Patients who have undergone splenectomy are at a higher risk for infections, particularly from encapsulated organisms such as Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria meningitidis. As a result, post-splenectomy care often includes:

• Vaccinations: Patients are typically advised to receive vaccinations against pneumococcal, meningococcal, and Haemophilus influenzae type b (Hib) infections.
• Prophylactic Antibiotics: In some cases, long-term antibiotic prophylaxis may be recommended, especially in children or those with additional risk factors.
• Regular Monitoring: Ongoing medical follow-up is essential to monitor for any signs of infection or other complications.

Documentation and Coding

When documenting the acquired absence of the spleen, healthcare providers should ensure that the medical record reflects the reason for the splenectomy, any relevant medical history, and the patient's current health status. This information is crucial for accurate coding and for providing appropriate care.

The ICD-10-CM code Z90.81 is part of the Z90 category, which encompasses codes related to the absence of organs and parts of the body. Proper coding is essential for billing, insurance claims, and epidemiological tracking of health conditions.

Conclusion

In summary, the ICD-10-CM code Z90.81 signifies the acquired absence of the spleen, a condition that can have significant implications for a patient's health, particularly regarding their immune response. Understanding the clinical aspects and management strategies associated with this condition is vital for healthcare providers to ensure optimal patient care and outcomes.

Clinical Presentation

Overview of Acquired Absence of Spleen

The spleen plays a vital role in the immune system, particularly in filtering blood and managing the body's response to infections. An acquired absence of the spleen can occur due to surgical removal (splenectomy) or as a result of trauma, certain diseases, or conditions that necessitate its removal. Patients may present with a history of splenectomy or conditions leading to splenic dysfunction.

Signs and Symptoms

Patients with an acquired absence of the spleen may exhibit the following signs and symptoms:

• Increased Susceptibility to Infections: The most significant clinical concern is the heightened risk of infections, particularly from encapsulated bacteria such as Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Patients may experience recurrent infections, which can manifest as:
• Fever
• Chills
• Sweats

• Fatigue

• Sepsis: In severe cases, patients may develop sepsis, characterized by systemic inflammatory response syndrome (SIRS) and organ dysfunction.

• Thrombocytosis: Some patients may present with elevated platelet counts (thrombocytosis) due to the lack of splenic filtration.

• Abdominal Pain: If the absence of the spleen is due to trauma or a surgical procedure, patients may report abdominal pain or discomfort.

• Signs of Hemolysis: In cases where the spleen was removed due to hematological disorders, patients may show signs of hemolysis, such as jaundice or dark urine.

Patient Characteristics

Certain patient characteristics may be associated with the acquired absence of the spleen:

• Demographics: There is no specific demographic that is exclusively affected, but individuals who have undergone splenectomy due to trauma, hematological disorders (like hereditary spherocytosis), or malignancies (such as lymphoma) are more likely to present with this condition.

• Medical History: A history of conditions leading to splenectomy, such as:

• Trauma (e.g., splenic rupture)
• Hematological disorders (e.g., thalassemia, sickle cell disease)
• Malignancies (e.g., certain cancers requiring splenectomy)

• Autoimmune diseases (e.g., idiopathic thrombocytopenic purpura)

• Immunization Status: Patients who have had their spleen removed should be up-to-date with vaccinations against encapsulated organisms, including pneumococcal, meningococcal, and Haemophilus influenzae type b (Hib) vaccines, to mitigate the risk of infections.
