C32 is a non-billable ICD-10-CM category code for malignant neoplasm of larynx, so it cannot be submitted on claims. Use a more specific code from this category instead, such as C32.0, C32.1, C32.2, and C32.3.

Specific Coding for Malignant neoplasm of larynxOverview

Non-specific codes like C32 require more characters. Use one of these billable codes instead:

  • Use C32.0 for Malignant neoplasm of glottis

  • Use C32.1 for Malignant neoplasm of supraglottis

  • Use C32.2 for Malignant neoplasm of subglottis

  • Use C32.3 for Malignant neoplasm of laryngeal cartilage

  • Use C32.8 for Malignant neoplasm of overlapping sites of larynx

  • Use C32.9 for Malignant neoplasm of larynx, unspecified

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to C32: its own notes plus those printed at block C30-C39 and Chapter 2. A note printed at a category, block or chapter applies to every code under it.

Includes

Further defines, or gives examples of, the content of the category.

From Block C30-C39 Malignant neoplasms of respiratory and intrathoracic organs applies to 40 codes
  • malignant neoplasm of middle ear

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

From Block C30-C39 Malignant neoplasms of respiratory and intrathoracic organs applies to 40 codes

Use Additional Code

Add a second code, after this one, to fully describe the condition.

  • code to identify:
  • alcohol abuse and dependence (F10.-)
  • exposure to environmental tobacco smoke (Z77.22)
  • exposure to tobacco smoke in the perinatal period (P96.81)
  • history of tobacco dependence (Z87.891)
  • occupational exposure to environmental tobacco smoke (Z57.31)
  • tobacco dependence (F17.-)
  • tobacco use (Z72.0)

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 Laryngeal Neoplasm

    a primary or metastatic malignant neoplasm involving the larynx. the majority are carcinomas.

Patient EducationClinical

Throat Cancer

Throat cancer is a type of head and neck cancer. Throat cancer has different names, depending on which part of the throat is affected. The different parts of your throat are called the oropharynx, the hypopharynx, the nasopharynx, and the larynx, or voice box.

Questions About C32Overview

What is the ICD-10 code for malignant neoplasm of larynx?

C32 is the ICD-10-CM category for malignant neoplasm of larynx, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is C32 (Malignant neoplasm of larynx) a billable code?

No. This is a category header that groups the codes for malignant neoplasm of larynx, and headers cannot be submitted on claims. Claims for malignant neoplasm of larynx need a more specific code from this category, such as C32.0, C32.1, and C32.2.

Can C32 be reported with a code from C45?

Not as a rule. The Excludes1 note at block C30-C39, which applies to C32, lists "mesothelioma (C45.-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).

Does C32 need an additional code?

When the condition applies, yes. The Use Additional Code note reads: code to identify: alcohol abuse and dependence (F10.-); exposure to environmental tobacco smoke (Z77.22); exposure to tobacco smoke in the perinatal period (P96.81); history of tobacco dependence (Z87.891); occupational exposure to environmental tobacco smoke (Z57.31); and 2 more listed in the Instructional Notes section. The additional code is reported after C32.
