Code Classification

  • Diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism
    (D50–D89)
    • Neoplasms of unspecified behavior
      (D49)
      • Neoplasms of unspecified behavior
        (D49)

D49.0 is a billable diagnosis code used to specify a medical diagnosis of neoplasm of unspecified behavior of digestive system. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

The following anatomical sites found in the Table of Neoplasms reference this diagnosis code given the correct histological behavior: Neoplasm, neoplastic adenoid (pharynx) (tissue) ; Neoplasm, neoplastic alimentary canal or tract NEC ; Neoplasm, neoplastic alveolar ; Neoplasm, neoplastic alveolar mucosa ; Neoplasm, neoplastic alveolar mucosa lower ; Neoplasm, neoplastic alveolar mucosa upper ; Neoplasm, neoplastic alveolar ridge or process mucosa ; etc

Unspecified diagnosis codes like D49.0 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.

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.


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.
  • neoplasm of unspecified behavior of margin of anus D49.2
  • neoplasm of unspecified behavior of perianal skin D49.2
  • neoplasm of unspecified behavior of skin of anus D49.2

Table of Neoplasms

This code is referenced in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

Patient Education


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.
