Diseases of spleen (D73)

The D73 ICD-10 codes cover a range of diseases affecting the spleen, an important organ in blood filtration and immune function. These codes specify different spleen conditions like hyposplenism, hypersplenism, and splenic infarction, helping healthcare providers accurately classify spleen-related diagnoses.

The ICD-10 code for Hyposplenism (D73.0), also called hypoplasia of the spleen or splenic atrophy, identifies reduced spleen function. Hypersplenism (D73.1) refers to an overactive spleen, sometimes associated with myeloid metaplasia or thrombocytopenia due to hypersplenism. Chronic congestive splenomegaly (D73.2) codes describe an enlarged spleen caused by prolonged congestion. Abscesses (splenic abscess, D73.3) and cysts (epidermoid or peliosis spleen, D73.4) involve localized lesions within the spleen. The code D73.5 includes infarctions and various hemorrhagic or rupture conditions of the spleen. Other codes like D73.81 cover neutropenic splenomegaly while D73.89 captures diverse diseases such as lymphoid hyperplasia, splenitis, and splenic fibrosis. The unspecified category (D73.9) is used when a precise spleen disease diagnosis is unknown. This ICD-10 code section provides precise classification critical for diagnosis and treatment planning of spleen disorders.

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Hypersplenism

Condition characterized by splenomegaly, some reduction in the number of circulating blood cells in the presence of a normal or hyperactive bone marrow, and the potential for reversal by splenectomy.

Splenic Infarction

Insufficiency of arterial or venous blood supply to the spleen due to emboli, thrombi, vascular torsion, or pressure that produces a macroscopic area of necrosis. (From Stedman, 25th ed)

Splenosis

The spontaneous transplantation of splenic tissue to unusual sites after open splenic trauma, e.g., after automobile accidents, gunshot or stab wounds. The splenic pulp implants appear as red-blue nodules on the peritoneum, omentum, and mesentery, morphologically similar to multifocal pelvic endometriosis. (Segen, Dictionary of Modern Medicine, 1992)

Wandering Spleen

A congenital or acquired condition in which the SPLEEN is not in its normal anatomical position but moves about in the ABDOMEN. This is due to laxity or absence of suspensory ligaments which normally provide peritoneal attachments to keep the SPLEEN in a fixed position. Clinical symptoms include ABDOMINAL PAIN, splenic torsion and ISCHEMIA.
