Malignant neoplasm of aryepiglottic fold, hypopharyngeal aspect
Billable / specificHCC V28 21
C13.1 is a billable, specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes in FY2027.
Inclusion terms
Applicable to
- Malignant neoplasm of aryepiglottic fold, marginal zone
- Malignant neoplasm of aryepiglottic fold NOS
- Malignant neoplasm of interarytenoid fold, marginal zone
- Malignant neoplasm of interarytenoid fold NOS
Includes (from C13)
- Note: Functional activity
- Note: 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.
- Note: Morphology [Histology]
- Note: 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.
- Note: Primary malignant neoplasms overlapping site boundaries
- Note: 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.
- Note: Malignant neoplasm of ectopic tissue
- Note: 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).
