Not Valid for Submission
R18 is a "header" nonspecific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of ascites. The code is NOT valid for the year 2021 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.
Specific Coding for Ascites
Header codes like R18 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for ascites:

Type 1 ExcludesType 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- ASCITES-. accumulation or retention of free fluid within the peritoneal cavity.
- CARCINOMA EHRLICH TUMOR-. a transplantable poorly differentiated malignant tumor which appeared originally as a spontaneous breast carcinoma in a mouse. it grows in both solid and ascitic forms.
- CHYLOUS ASCITES-. presence of milky lymph chyle in the peritoneal cavity with or without infection.
- PERITONEOVENOUS SHUNT-. an operation for the continuous emptying of ascitic fluid into the venous system. fluid removal is based on intraperitoneal and intrathoracic superior vena cava pressure differentials and is performed via a pressure sensitive one way valve connected to a tube traversing the subcutaneous tissue of the chest wall to the neck where it enters the internal jugular vein and terminates in the superior vena cava. it is used in the treatment of intractable ascites.
- PSEUDOMYXOMA PERITONEI-. a condition characterized by poorly circumscribed gelatinous masses filled with malignant mucin secreting cells. forty five percent of pseudomyxomas arise from the ovary usually in a mucinous cystadenocarcinoma cystadenocarcinoma mucinous which has prognostic significance. pseudomyxoma peritonei must be differentiated from mucinous spillage into the peritoneum by a benign mucocele of the appendix. segen dictionary of modern medicine 1992
- MUCIN 4-. a transmembrane mucin that is found in a broad variety of epithelial tissue. mucin 4 may play a role in regulating cellular adhesion and in cell surface signaling from the erbb 2 receptor protein tyrosine kinase. mucin 4 is a heterodimer of alpha and beta chains. the alpha and beta chains result from the proteolytic cleavage of a precursor protein.
Information for Patients
Also called: Hepatic disease
Your liver is the largest organ inside your body. It helps your body digest food, store energy, and remove poisons.
There are many kinds of liver diseases:
- Diseases caused by viruses, such as hepatitis A, hepatitis B, and hepatitis C
- Diseases caused by drugs, poisons, or too much alcohol. Examples include fatty liver disease and cirrhosis.
- Liver cancer
- Inherited diseases, such as hemochromatosis and Wilson disease
Symptoms of liver disease can vary, but they often include swelling of the abdomen and legs, bruising easily, changes in the color of your stool and urine, and jaundice, or yellowing of the skin and eyes. Sometimes there are no symptoms. Tests such as imaging tests and liver function tests can check for liver damage and help to diagnose liver diseases.
