Code Classification

  • Diseases of the digestive system
    (K00–K95)
    • Other diseases of intestines
      (K55-K64)
      • Paralytic ileus and intestinal obstruction without hernia
        (K56)

K56.609 is a billable diagnosis code used to specify a medical diagnosis of unspecified intestinal obstruction, unspecified as to partial versus complete obstruction. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like K56.609 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Clinical Classification

Clinical Information

    any impairment, arrest, or reversal of the normal flow of intestinal contents toward the anal canal.

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.
  • Intestinal obstruction NOS

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).

Replacement Code

K56609 replaces the following previously assigned ICD-10-CM code(s):

  • K56.60 - Unspecified intestinal obstruction

Convert K56.609 to ICD-9-CM

  • ICD-9-CM Code: 560.9 - Intestinal obstruct NOS
    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


Intestinal Obstruction

An intestinal obstruction occurs when food or stool cannot move through the intestines. The obstruction can be complete or partial. There are many causes. The most common are adhesions, hernias, cancers, and certain medicines.

Symptoms include:

  • Severe abdominal pain or cramping
  • Vomiting
  • Bloating
  • Loud bowel sounds
  • Swelling of the abdomen
  • Inability to pass gas
  • Constipation

A complete intestinal obstruction is a medical emergency. It often requires surgery.

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.
