ICD-10-CM Code D37.05

Neoplasm of uncertain behavior of pharynx

Version 2020 Billable Code Neoplasm Uncertain Behavior

Valid for Submission

D37.05 is a billable code used to specify a medical diagnosis of neoplasm of uncertain behavior of pharynx. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code D37.05 might also be used to specify conditions or terms like mass of vallecula of epiglottis, neoplasm of adenoid, neoplasm of anterior aspect of epiglottis, neoplasm of anterior wall of nasopharynx, neoplasm of hypopharyngeal aspect of interarytenoid fold, neoplasm of junctional region of epiglottis, etc

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: adenoid (pharynx) (tissue) ; aryepiglottic fold ; aryepiglottic fold hypopharyngeal aspect ; aryepiglottic fold marginal zone ; auditory tube opening ; branchial (cleft) (cyst) (vestiges) ; cartilage (articular) (joint) NEC [See Also: Neoplasm, bone] epiglottis anterior surface ; etc

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 guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code D37.05:

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 D37.05 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


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.
