| ICD-10: | C31.3 |
| Short Description: | Malignant neoplasm of sphenoid sinus |
| Long Description: | Malignant neoplasm of sphenoid sinus |
| Status: | Valid for Submission |
| Version: | ICD-10-CM 2023 |
| Code Classification: |
C31.3 is a billable ICD-10 code used to specify a medical diagnosis of malignant neoplasm of sphenoid 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 sinus (accessory) sphenoid or Neoplasm, neoplastic sphenoid or Neoplasm, neoplastic sphenoid sinus .
Approximate Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis 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.
