Clinical Classification

Clinical Information

  • Low Anterior Resection Syndrome

    postoperative complication after removal of the rectum (low anterior resection surgery or resection surgery to the lower part of the colon). it includes disordered rectum function, e.g., frequent bowel movement; fecal incontinence; and constipation.
  • Xerostomia

    decreased salivary flow.
  • Bile Duct Leakage

    the leakage of bile into the abdominal cavity as a result of injury to the bile duct.
  • Esophageal Anastomotic Stricture

    luminal narrowing at the site of surgical resection and reconstruction of the esophagus.
  • Recurrent Esophageal Anastomotic Stricture

    recurrence of an esophageal anastomotic stricture following therapeutic dilation.
  • Refractory Esophageal Anastomotic Stricture

    esophageal anastomotic stricture that remains narrowed despite repeated therapeutic dilations.
  • Low Anterior Resection Syndrome

    a collection of symptoms following removal of part or all of the rectum that may include frequency or urgency of stools, numerous bowel movements over a few hours, fecal incontinence, constipation alternating with numerous bowel movements, and/or increased intestinal gas.

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.


Use Additional Code

Use 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.
  • code, if applicable, to further specify disorder

Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Patient Education


After Surgery

After any operation, you'll have some side effects. There is usually some pain with surgery. There may also be swelling and soreness around the area that the surgeon cut. Your surgeon can tell you which side effects to expect.

There can also be complications. These are unplanned events linked to the operation. Some complications are infection, too much bleeding, reaction to anesthesia, or accidental injury. Some people have a greater risk of complications because of other medical conditions.

Your surgeon can tell you how you might feel and what you will be able to do - or not do - the first few days, weeks, or months after surgery. Some other questions to ask are:

  • How long you will be in the hospital
  • What kind of supplies, equipment, and help you might need when you go home
  • When you can go back to work
  • When it is ok to start exercising again
  • Are they any other restrictions in your activities

Following your surgeon's advice can help you recover as soon as possible.

Digestive Diseases

When you eat, your body breaks food down to a form it can use to build and nourish cells and provide energy. This process is called digestion.

Your digestive system is a series of hollow organs joined in a long, twisting tube. It runs from your mouth to your anus and includes your esophagus, stomach, and small and large intestines. Your liver, gallbladder and pancreas are also involved. They produce juices to help digestion.

There are many types of digestive disorders. The symptoms vary widely depending on the problem. In general, you should see your doctor if you have:

  • Blood in your stool
  • Changes in bowel habits
  • Severe abdominal pain
  • Unintentional weight loss
  • Heartburn not relieved by antacids

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.
