Code Classification

  • Diseases of the digestive system
    (K00–K95)

K66.0 is a billable diagnosis code used to specify a medical diagnosis of peritoneal adhesions (postprocedural) (postinfection). The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Clinical Classification

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


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

Index to Diseases and Injuries References

The following annotation back-references for this diagnosis code are found in the injuries and diseases index. The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10-CM code(s).

Convert K66.0 to ICD-9-CM

  • ICD-9-CM Code: 568.0 - Peritoneal adhesions
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education


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.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
