2022 ICD-10-CM Code C31.0

Malignant neoplasm of maxillary sinus

Version 2021

Valid for Submission

ICD-10:C31.0
Short Description:Malignant neoplasm of maxillary sinus
Long Description:Malignant neoplasm of maxillary sinus

Code Classification

  • Neoplasms (C00–D48)
    • Malignant neoplasms of respiratory and intrathoracic organs (C30-C39)
      • Malignant neoplasm of accessory sinuses (C31)

C31.0 is a billable diagnosis code used to specify a medical diagnosis of malignant neoplasm of maxillary sinus. The code C31.0 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.

The ICD-10-CM code C31.0 might also be used to specify conditions or terms like malignant melanoma of accessory sinus, malignant melanoma of maxillary sinus, malignant tumor of maxillary sinus, maxillary sinus tnm finding, maxillary sinus tnm finding , maxillary sinus tnm finding, etc.

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: antrum (Highmore) (maxillary) or maxilla, maxillary (superior) antrum or maxilla, maxillary (superior) sinus or sinus (accessory) maxillary .

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code C31.0:


Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Table of Neoplasms

The code C31.0 is included 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.

Information for Patients


Nasal Cancer

Your paranasal sinuses are small hollow spaces around the nose. They are lined with cells that make mucus, which keeps your nose from drying out. The nasal cavity is the passageway just behind your nose. Air passes through it on the way to your throat as you breathe.

Cancer of the nasal cavity and paranasal sinuses is rare. You are at greater risk if you are

There may be no symptoms at first, and later symptoms can be like those of infections. Doctors diagnose nasal cancer with imaging tests, lighted tube-like instruments that look inside the nose, and biopsies. Treatment options include surgery, radiation, and chemotherapy.
