Diseases Of Spleen – Definitions & ICD 11 Codes

Congenital disorders of spleen

Definition of Congenital disorders of spleen: Any condition caused by a failure of the spleen to correctly develop in the antenatal period.

ICD 11 Code For Congenital disorders of spleen

 3B80  Congenital disorders of spleen

Coded Elsewhere:

  • Structural developmental anomalies of spleen (LB22)

3B80.0 Splenomegaly in storage diseases

Definition of Splenomegaly in storage diseases: A disease caused by storage diseases; genetically inherited metabolic disorders that result from defects in lysosomal, lipid or glycogen function, of the spleen. This disease is characterised by enlargement of the spleen. This disease may present with abdominal pain, chest pain, pallor, shortness of breath fatigue. Confirmation is through medical imaging.

Acquired disorders of spleen

Definition of Acquired disorders of spleen: Any condition caused by determinants acquired after birth, leading to dysfunction of the spleen.

ICD 11 Code For Acquired disorders of spleen

  3B81  Acquired disorders of spleen

Coded Elsewhere:

  • Injury of spleen (NB91.0)
  • Primary neoplasms of the spleen (2C11.Z)

3B81.0 Tumour-like conditions of spleen

Definition of Tumour-like conditions of spleen: Any condition caused by determinants acquired after birth, in the antenatal period or genetically inherited factors, leading to tumour-like conditions of the spleen. Confirmation is through medical imaging.

3B81.1 Postsurgical asplenia

Definition of Postsurgical asplenia: A disease caused by underlying diseases, splenectomy or splenic rupture from trauma. This disease is characterised by absence of normal spleen function. This disease may present with increased susceptibility to infection. Confirmation is through medical imaging.

3B81.2 Atrophy of spleen

Definition of Atrophy of spleen: A disease caused by determinants arising after birth, during the antenatal period or by genetically inherited factors. This disease is characterised by partial or complete degradation of the spleen. This disease may present with increased susceptibility to infection. Confirmation is through medical imaging.

3B81.3 Nontraumatic laceration or rupture of spleen

Definition of Nontraumatic laceration or rupture of spleen: A disease caused by non-traumatically determinants such as infectious diseases, medical procedures such as colonoscopy, haematological diseases, medications, or pregnancy. This disease is characterised by laceration or rupturing of the spleen leading to lack of function. This disease may present with bleeding and increased susceptibility of infection. Confirmation is through medical imaging.

3B81.4 Splenosis

Definition of Splenosis: A diseased caused by determinants arising after birth such as physical trauma or splenectomy . This disease is characterised by autoimplantation one or more focal deposits of splenic tissue in various compartments of the body. Confirmation is through medical imaging.

3B81.5 Splenic cyst or pseudocyst

3B81.50 Pseudocyst of spleen

Definition of Pseudocyst of spleen: A disease caused by determinants arising after birth, during the antenatal period or by genetically inherited factors. This disease is characterised by a noncancerous fluid-filled sac, pseudocysts are like cysts, but lack epithelial or endothelial cells. This disease is often asymptomatic but may present with abdominal pain, nausea and vomiting. Confirmation is through medical imaging.

3B81.51 Epithelial cyst of spleen

3B81.5Y Other specified splenic cyst

3B81.5Z Splenic cyst unspecified

3B81.6 Infarction of spleen

Definition of Infarction of spleen: A disease caused by determinants such as trauma, infection, or inherited factors leading to a shortage of oxygen in the spleen. This disease is characterised by death of spleen tissue and loss of function. Confirmation is by medical imaging.

Exclusions:

  • traumatic rupture of spleen (NB91.0)

3B81.7 Infection of spleen

Definition of Infection of spleen: Any condition of the spleen, caused by an infection with a bacterial, viral, fungal, or parasitic source.

3B81.70 Acute septic splenitis

Inclusions:

  • septic spleen

3B81.71 Abscess of spleen

Definition of Abscess of spleen: This is a collection of pus (neutrophils) that has accumulated within a tissue because of an inflammatory process in response to either an infectious process (usually caused by bacteria or parasites) or other foreign materials (e.g., splinters, bullet wounds, or injecting needles), in the spleen.

3B81.7Y Other specified infection of spleen

3B81.7Z Infection of spleen unspecified

3B81.8 Torsion of spleen

Definition of Torsion of spleen: A disease caused by abnormal development of splenic suspensory ligaments. This disease is characterised by twisting of the spleen leading to splenic infarction. This disease may present with abdominal pain. Confirmation is through medical imaging.

3B81.9 Fibrosis of spleen

Definition of Fibrosis of spleen: A disease caused by determinants arising after birth, during the antenatal period or by genetically inherited factors. This disease is characterised by formation of excess fibrous connective tissue leading to partial or complete degradation of the spleen. This disease may present with increased susceptibility to infection. Confirmation is through medical imaging.

Coding Note:

  • Code also the causing condition

3B81.A Perisplenitis

Definition of Perisplenitis: A disease caused by bacterial or viral infection, parasite infestation, or cysts. This disease is characterised by inflammation of the peritoneal surface of the spleen. This disease may present with abdominal pain, susceptibility to infection and enlargement of the spleen. Confirmation is by identification of infection in a blood sample.

3B81.B Hypersplenism

Definition of Hypersplenism: A disease caused by determinants such as cirrhosis, malaria, tuberculosis or inflammatory disorders leading overactive spleen function. This disease is characterised by the presence of an enlarged spleen. Confirmation is by identification through medical imaging.

Exclusions:

  • Splenomegaly, not elsewhere classified (ME10.01)
  • congenital splenomegaly (LB22)

3B81.C Chronic congestive splenomegaly

Definition of Chronic congestive splenomegaly: A form of exaggerated spleen function characterised by splenic enlargement secondary to splenic vein thrombosis and/or portal hypertension

3B81.Y Other specified acquired disorders of spleen
