Not Valid for Submission
K65 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of peritonitis. The code is not specific and 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 Peritonitis
Non-specific codes like K65 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 peritonitis:
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code K65:
Code AlsoCode Also
A "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.
- if applicable diverticular disease of intestine K57
Use Additional CodeUse Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
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.

- CHYLOUS ASCITES-. presence of milky lymph chyle in the peritoneal cavity with or without infection.
- FAMILIAL MEDITERRANEAN FEVER-. a group of hereditary autoinflammation diseases characterized by recurrent fever abdominal pain headache rash pleurisy; and arthritis. orchitis; benign meningitis; and amyloidosis may also occur. homozygous or compound heterozygous mutations in marenostrin gene result in autosomal recessive transmission; simple heterozygous autosomal dominant form of the disease.
- PERITONITIS-. inflammation of the peritoneum lining the abdominal cavity as the result of infectious autoimmune or chemical processes. primary peritonitis is due to infection of the peritoneal cavity via hematogenous or lymphatic spread and without intra abdominal source. secondary peritonitis arises from the abdominal cavity itself through rupture or abscess of intra abdominal organs.
- PERITONITIS TUBERCULOUS-. a form of peritonitis seen in patients with tuberculosis characterized by lesion either as a miliary form or as a pelvic mass on the peritoneal surfaces. most patients have ascites abdominal swelling abdominal pain and other systemic symptoms such as fever; weight loss; and anemia.
- CORONAVIRUS FELINE-. a species of coronavirus infecting cats of all ages and commonly found in catteries and zoos. cats are often found carrying the virus but only a small proportion develop disease. feline coronavirus and feline infectious peritonitis virus fipv are virtually the same virus in genetic and antigenetic terms and are morphologically indistinguishable. since they only differ in their disease potential with fipv causing a more serious illness they are considered biotypes of each other.
- FELINE INFECTIOUS PERITONITIS-. common coronavirus infection of cats caused by the feline infectious peritonitis virus coronavirus feline. the disease is characterized by a long incubation period fever depression loss of appetite wasting and progressive abdominal enlargement. infection of cells of the monocyte macrophage lineage appears to be essential in fip pathogenesis.
Information for Patients
Your peritoneum is the tissue that lines your abdominal wall and covers most of the organs in your abdomen. A liquid, peritoneal fluid, lubricates the surface of this tissue.
Disorders of the peritoneum are not common. They include
- Peritonitis - an inflammation of the peritoneum
- Complications from peritoneal dialysis
Your doctor may use imaging tests or lab tests to analyze the peritoneal fluid to diagnose the problem. Treatment of peritoneal disorders depends on the cause.
