C74 is a non-billable ICD-10-CM category code for malignant neoplasm of adrenal gland, so it cannot be submitted on claims. Use a more specific code from this category instead, such as C74.00, C74.01, C74.02, and C74.10.

Specific Coding for Malignant neoplasm of adrenal glandOverview

Non-specific codes like C74 require more characters. Use one of these billable codes instead:

  • C74.0 for Malignant neoplasm of cortex of adrenal gland

  • Use C74.00 for Malignant neoplasm of cortex of unspecified adrenal gland

  • Use C74.01 for Malignant neoplasm of cortex of right adrenal gland

  • Use C74.02 for Malignant neoplasm of cortex of left adrenal gland

  • C74.1 for Malignant neoplasm of medulla of adrenal gland

  • Use C74.10 for Malignant neoplasm of medulla of unspecified adrenal gland

  • Use C74.11 for Malignant neoplasm of medulla of right adrenal gland

  • Use C74.12 for Malignant neoplasm of medulla of left adrenal gland

  • C74.9 for Malignant neoplasm of unspecified part of adrenal gland

  • Use C74.90 for Malignant neoplasm of unspecified part of unspecified adrenal gland

  • Use C74.91 for Malignant neoplasm of unspecified part of right adrenal gland

  • Use C74.92 for Malignant neoplasm of unspecified part of left adrenal gland

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to C74: its own notes plus those printed at Chapter 2. A note printed at a category, block or chapter applies to every code under it.

Notes

General instructions on how these codes are used.

From Chapter 2 (C00-D49) Neoplasms applies to 1,730 codes
  • 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).

Clinical InformationClinical

  • Malignant Adrenal Gland Neoplasm

    a primary or metastatic malignant neoplasm that affects the adrenal gland.

Patient EducationClinical

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.
