C31.0 - Malignant neoplasm of maxillary sinus
| ICD-10: | C31.0 |
| Short Description: | Malignant neoplasm of maxillary sinus |
| Long Description: | Malignant neoplasm of maxillary sinus |
| Status: | Valid for Submission |
| Version: | ICD-10-CM 2023 |
| Code Classification: |
C31.0 is a billable ICD-10 code used to specify a medical diagnosis of malignant neoplasm of maxillary sinus. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
The following anatomical sites found in the Table of Neoplasms reference this diagnosis code given the correct histological behavior: Neoplasm, neoplastic antrum (Highmore) (maxillary) or Neoplasm, neoplastic maxilla, maxillary (superior) antrum or Neoplasm, neoplastic maxilla, maxillary (superior) sinus or Neoplasm, neoplastic sinus (accessory) maxillary .
Approximate Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- 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

- Primary adenocarcinoma of accessory sinus
- Primary adenocarcinoma of maxillary sinus
- Primary carcinoma of maxillary sinus
- Primary malignant neoplasm of maxillary sinus
- Primary squamous cell carcinoma of accessory sinus
- Primary squamous cell carcinoma of maxillary sinus
- pT1: Tumor limited to the maxillary sinus mucosa with no erosion or destruction of bone
- pT2: Tumor causing bone erosion or destruction including extension into the hard palate and/or middle nasal meatus, except extension to posterior wall of maxillary sinus and pterygoid plates
- pT3: Tumor invades any of the following: bone of the posterior wall of maxillary sinus, subcutaneous tissues, floor or medial wall of orbit, pterygoid fossa, ethmoid sinuses
- pT4a: Tumor invades anterior orbital contents, skin of cheek, pterygoid plates, infratemporal fossa, cribriform plate, sphenoid or frontal sinuses
- pT4b: Tumor invades any of the following: orbital apex, dura, brain, middle cranial fossa, cranial nerves other than maxillary division of trigeminal nerve, nasopharynx, or clivus
- T1: Tumor limited to the antral mucosa with no erosion or destruction of bone
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 this diagnosis code:
Inclusion Terms
Inclusion TermsThese 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
This code is referenced 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.

Patient Education
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:
- Male and over 40 years old
- Exposed to certain workplace chemicals
- Infected with HPV
- A smoker
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.
