Clinical Information
Oropharyngeal Neoplasms
tumors or cancer of the oropharynx.Oropharynx
the middle portion of the pharynx that lies posterior to the mouth, inferior to the soft palate, and superior to the base of the tongue and epiglottis. it has a digestive function as food passes from the mouth into the oropharynx before entering esophagus.
Tabular List of Diseases and Injuries
The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.
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.
- Neoplasm of uncertain behavior of aryepiglottic fold of pharynx NOS
- Neoplasm of uncertain behavior of hypopharyngeal aspect of aryepiglottic fold of pharynx
- Neoplasm of uncertain behavior of marginal zone of aryepiglottic fold of pharynx
Convert D37.05 to ICD-9-CM
- ICD-9-CM Code: 235.1 - Unc behav neo oral/phar
Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original 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
Throat Disorders
Your throat is a tube that carries food to your esophagus and air to your windpipe and larynx. The technical name for your throat is the pharynx.
Throat problems are common. You've probably had a sore throat. The cause is usually a viral infection, but other causes include allergies, infection with strep bacteria or the leaking of stomach acids back up into the esophagus, called GERD.
Other problems that affect the throat include:
- Tonsillitis - inflammation of the tonsils
- Cancer
- Croup - inflammation, usually in small children, which causes a barking cough
- Laryngitis - swelling of the voice box, which can cause a hoarse voice or loss of voice
Most throat problems are minor and go away on their own. Treatments, when needed, depend on the problem.

Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
