C74.91 - Malignant neoplasm of unspecified part of right adrenal gland
| ICD-10: | C74.91 |
| Short Description: | Malignant neoplasm of unsp part of right adrenal gland |
| Long Description: | Malignant neoplasm of unspecified part of right adrenal gland |
| Status: | Valid for Submission |
| Version: | ICD-10-CM 2023 |
| Code Classification: |
C74.91 is a billable ICD-10 code used to specify a medical diagnosis of malignant neoplasm of unspecified part of right adrenal gland. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
The following anatomical sites found in the Table of Neoplasms reference the parent code C74.9 of the current diagnosis code given the correct histological behavior: Neoplasm, neoplastic adrenal ; Neoplasm, neoplastic adrenal capsule ; Neoplasm, neoplastic adrenal gland ; Neoplasm, neoplastic suprarenal ; Neoplasm, neoplastic suprarenal capsule ; Neoplasm, neoplastic suprarenal gland ; etc
Unspecified diagnosis codes like C74.91 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.
Approximate Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Malignant pheochromocytoma
- Primary malignant neoplasm of right adrenal gland
- Primary malignant pheochromocytoma of right adrenal gland

Table of Neoplasms
The parent code C74.9 of the current diagnosis 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
Adrenal Gland Cancer
Your adrenal, or suprarenal, glands are located on the top of each kidney. These glands produce hormones that you can't live without, including sex hormones and cortisol, which helps you respond to stress and has many other functions.
A number of disorders can affect the adrenal glands, including tumors. Tumors can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. Most adrenal gland tumors are benign. They usually do not cause symptoms and may not require treatment. Malignant adrenal gland cancers are uncommon.
Types of tumors include:
- Adrenocortical carcinoma - cancer in the outer part of the gland
- Neuroblastoma, a type of childhood cancer
- Pheochromocytoma - a rare tumor that is usually benign
Symptoms depend on the type of cancer you have. Treatments may include surgery, chemotherapy, or radiation therapy.
