Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation. In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere." Codes with this title are a component of the etiology/manifestation convention. The code title indicates that it is a manifestation code. "In diseases classified elsewhere" codes are never permitted to be used as first listed or principle diagnosis codes. They must be used in conjunction with an underlying condition code and they must be listed following the underlying condition.

Clinical Information
  • A disorder characterized by an increase in blood pressure in the portal venous system.
  • Abnormal increase of resistance to blood flow within the hepatic portal system, frequently seen in liver cirrhosis and conditions with obstruction of the portal vein.
  • Abnormally increased pressure in the portal venous system, frequently seen in cirrhosis of the liver and other conditions causing obstruction of the portal vein.
  • High blood pressure in the vein that carries blood to the liver from the stomach, small and large intestines, spleen, pancreas, and gallbladder. It is usually caused by a block in the blood flow through the liver due to cirrhosis (scarring) of the liver.
  • Increased blood pressure in the portal venous system. It is most commonly caused by cirrhosis. Other causes include portal vein thrombosis, budd-chiari syndrome, and right heart failure. Complications include ascites, esophageal varices, encephalopathy, and splenomegaly.
