ICD-10-CM Code C18.9

C18.9 is a billable code used to specify a medical diagnosis of malignant neoplasm of colon, unspecified. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code C18.9 might also be used to specify conditions or terms like adenocarcinoma of large intestine, carcinoma of colon, carcinoma of colon, stage i, carcinoma of colon, stage ii, carcinoma of colon, stage iii, carcinoma of colon, stage iv, etc

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: colon [See Also: Neoplasm, intestine, large] or intestine, intestinal large or intestine, intestinal large colon .

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 C18.9:

Inclusion Terms

Inclusion TermsThese 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.

Diagnostic Related Groups

The ICD-10 code C18.9 is grouped in the following groups for version MS-DRG V37.0 What are Diagnostic Related Groups?The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2020 through 09/30/2020.

Convert C18.9 to ICD-9

The code C18.9 is included 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.

Colorectal Cancer

The colon and rectum are part of the large intestine. Colorectal cancer occurs when tumors form in the lining of the large intestine. It is common in both men and women. The risk of developing colorectal cancer rises after age 50. You're also more likely to get it if you have colorectal polyps, a family history of colorectal cancer, ulcerative colitis or Crohn's disease, eat a diet high in fat, or smoke.

Symptoms of colorectal cancer include

Diarrhea or constipation
A feeling that your bowel does not empty completely
Blood (either bright red or very dark) in your stool
Stools that are narrower than usual
Frequent gas pains or cramps, or feeling full or bloated
Weight loss with no known reason
Fatigue
Nausea or vomiting

Because you may not have symptoms at first, it's important to have screening tests. Everyone over 50 should get screened. Tests include colonoscopy and tests for blood in the stool. Treatments for colorectal cancer include surgery, chemotherapy, radiation, or a combination. Surgery can usually cure it when it is found early.
