C67.0 is a billable diagnosis code used to specify a medical diagnosis of malignant neoplasm of trigone of bladder. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2024 through September 30, 2025.

The following anatomical sites found in the Table of Neoplasms reference this diagnosis code given the correct histological behavior: Neoplasm, neoplastic bladder (urinary) trigone .

Approximate Synonyms

The following list of clinical terms are approximate synonyms, alternative descriptions, or common phrases that might be used by patients, healthcare providers, or medical coders to describe the same condition. These synonyms and related diagnosis terms are often used when searching for an ICD-10 code, especially when the exact medical terminology is unclear. Whether you're looking for lay terms, similar diagnosis names, or common language alternatives, this list can help guide you to the correct ICD-10 classification.

  • Adenocarcinoma of urinary bladder
  • Malignant tumor of trigone of urinary bladder
  • Neoplasm of trigone of urinary bladder
  • Neoplasm of trigone of urinary bladder
  • Neoplasm of trigone of urinary bladder
  • Neoplasm of trigone of urinary bladder
  • Primary adenocarcinoma of trigone of urinary bladder
  • Primary adenocarcinoma of urinary bladder
  • Primary malignant neoplasm of trigone of urinary bladder
  • Primary transitional cell carcinoma of trigone of urinary bladder
  • Primary transitional cell carcinoma of urinary bladder

Clinical Classification

Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.

They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.

Urinary system cancers - bladder

CCSR Code: NEO043

Inpatient Default: Y - Yes, default inpatient assignment for principal diagnosis or first-listed diagnosis.

Outpatient Default: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.

Convert C67.0 to ICD-9-CM

Below are the ICD-9 codes that most closely match this ICD-10 code, based on the General Equivalence Mappings (GEMs). This ICD-10 to ICD-9 crosswalk tool is helpful for coders who need to reference legacy diagnosis codes for audits, historical claims, or approximate code comparisons.

Mal neo bladder-trigone

ICD-9-CM: 188.0

This is a direct match with no additional mapping qualifiers. The absence of a flag generally means the mapping is considered exact or precise. In other words, the ICD-10 code maps cleanly to the ICD-9 code without qualification, approximation, or needing multiple codes.

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


Bladder Cancer

The bladder is a hollow organ in your lower abdomen that stores urine. Bladder cancer occurs in the lining of the bladder. It is the sixth most common type of cancer in the United States.

Symptoms include:

  • Blood in your urine
  • A frequent urge to urinate
  • Pain when you urinate
  • Low back pain

Risk factors for developing bladder cancer include smoking and exposure to certain chemicals in the workplace. People with a family history of bladder cancer or who are older, white, or male have a higher risk.

Treatments for bladder cancer include surgery, radiation therapy, chemotherapy, and biologic therapy. Biologic therapy boosts your body's own ability to fight cancer.

Bladder cancer

Bladder cancer is a disease in which certain cells in the bladder become abnormal and multiply uncontrollably to form a tumor. The bladder is a muscular organ in the lower abdomen that stores urine until it can be removed (excreted) from the body.

Bladder cancer may cause blood in the urine, pain during urination, frequent urination, the feeling of needing to urinate without being able to, or lower back pain. Many of these signs and symptoms are nonspecific, which means they may occur in multiple disorders. People who have one or more of these nonspecific health problems often do not have bladder cancer, but have another condition such as an infection.

Bladder cancer develops when tumors form in the tissue that lines the bladder. There are several types of bladder cancer, categorized by the type of cell in the tissue that becomes cancerous. The most common type is transitional cell carcinoma (also known as urothelial carcinoma); others include squamous cell carcinoma and adenocarcinoma. If the tumor spreads  (metastasizes) beyond the lining of the bladder into nearby tissues or organs, it is known as invasive bladder cancer.
