2021 ICD-10-CM Diagnosis Code C74

Malignant neoplasm of adrenal gland

    2016 2017 2018 2019 2020 2021 Non-Billable/Non-Specific Code
  • C74 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
  • The 2021 edition of ICD-10-CM C74 became effective on October 1, 2020.
  • This is the American ICD-10-CM version of C74 - other international versions of ICD-10 C74 may differ.
The following code(s) above C74 contain annotation back-references
Annotation Back-References
In this context, annotation back-references refer to codes that contain:
  • Applicable To annotations, or
  • Code Also annotations, or
  • Code First annotations, or
  • Excludes1 annotations, or
  • Excludes2 annotations, or
  • Includes annotations, or
  • Note annotations, or
  • Use Additional annotations
that may be applicable to C74:
  • C00-D49
    2021 ICD-10-CM Range C00-D49

    Neoplasms

    Note
    • Functional activity
    • All neoplasms are classified in this chapter, whether they are functionally active or not. An additional code from Chapter 4 may be used, to identify functional activity associated with any neoplasm.
    • Morphology [Histology]
    • Chapter 2 classifies neoplasms primarily by site (topography), with broad groupings for behavior, malignant, in situ, benign, etc. The Table of Neoplasms should be used to identify the correct topography code. In a few cases, such as for malignant melanoma and certain neuroendocrine tumors, the morphology (histologic type) is included in the category and codes.
    • Primary malignant neoplasms overlapping site boundaries
    • A primary malignant neoplasm that overlaps two or more contiguous (next to each other) sites should be classified to the subcategory/code .8 ('overlapping lesion'), unless the combination is specifically indexed elsewhere. For multiple neoplasms of the same site that are not contiguous, such as tumors in different quadrants of the same breast, codes for each site should be assigned.
    • Malignant neoplasm of ectopic tissue
    • Malignant neoplasms of ectopic tissue are to be coded to the site mentioned, e.g., ectopic pancreatic malignant neoplasms are coded to pancreas, unspecified (C25.9).
    Neoplasms
Clinical Information
  • A number of disorders can affect the adrenal glands, including several types of cancer. Adrenal gland cancers are uncommon. They include
    • adrenocortical carcinoma - cancer in the outer part of the gland
    • neuroblastoma, a type of childhood cancer
    • pheochromocytoma
    most adrenal gland tumors are non-cancerous adenomas that usually do not cause symptoms and may not require treatment.symptoms of adrenal gland cancer depend on the type of cancer you have. Treatments may include surgery, chemotherapy, or radiation therapy.
  • A primary or metastatic malignant neoplasm affecting the adrenal gland.
  • Cancer that forms in the tissues of the adrenal glands (two glands located just above the kidneys). The adrenal glands make hormones that control heart rate, blood pressure, and other important body functions. Adrenal cancer that starts in the outside layer of the adrenal gland is called adrenocortical carcinoma. Adrenal cancer that starts in the center of the adrenal gland is called malignant pheochromocytoma.
