Peritoneal adhesions (postprocedural) (postinfection)

Version 2020 Billable Code

Valid for Submission

K66.0 is a billable code used to specify a medical diagnosis of peritoneal adhesions (postprocedural) (postinfection). The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code K66.0 might also be used to specify conditions or terms like adhesion of abdominal wall, adhesion of diaphragm, adhesion of intestine, adhesion of mesentery, adhesion of omentum, adhesion of pelvic peritoneum, etc

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 guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code K66.0:

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Adhesions (of) abdominal (wall)
  • Adhesions (of) diaphragm
  • Adhesions (of) intestine
  • Adhesions (of) male pelvis
  • Adhesions (of) omentum
  • Adhesions (of) stomach
  • Adhesive bands
  • Mesenteric adhesions

Type 1 Excludes

Type 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.
  • female pelvic adhesions bands N73.6
  • peritoneal adhesions with intestinal obstruction K56.5

Information for Patients


Adhesions

Adhesions are bands of scar-like tissue. Normally, internal tissues and organs have slippery surfaces so they can shift easily as the body moves. Adhesions cause tissues and organs to stick together. They might connect the loops of the intestines to each other, to nearby organs, or to the wall of the abdomen. They can pull sections of the intestines out of place. This may block food from passing through the intestine.

Adhesions can occur anywhere in the body. But they often form after surgery on the abdomen. Almost everyone who has surgery on the abdomen gets adhesions. Some adhesions don't cause any problems. But when they partly or completely block the intestines, they cause symptoms such as

  • Severe abdominal pain or cramping
  • Vomiting
  • Bloating
  • An inability to pass gas
  • Constipation

Adhesions can sometimes cause infertility in women by preventing fertilized eggs from reaching the uterus.

No tests are available to detect adhesions. Doctors usually find them during surgery to diagnose other problems.

Some adhesions go away by themselves. If they partly block your intestines, a diet low in fiber can allow food to move easily through the affected area. If you have a complete intestinal obstruction, it is life-threatening. You should get immediate medical attention and may need surgery.

Peritoneal Disorders

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
  • Cancer
  • 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.
