D37.02 is a billable diagnosis code used to specify a medical diagnosis of neoplasm of uncertain behavior of tongue. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2025 through September 30, 2026.

The following anatomical sites found in the Table of Neoplasms reference this diagnosis code given the correct histological behavior: Neoplasm, neoplastic frenulum ; Neoplasm, neoplastic frenulum linguae ; Neoplasm, neoplastic lingual NEC [See Also: Neoplasm, tongue] ; Neoplasm, neoplastic tongue ; Neoplasm, neoplastic tongue anterior (two-thirds) NEC ; Neoplasm, neoplastic tongue anterior (two-thirds) NEC dorsal surface ; Neoplasm, neoplastic tongue anterior (two-thirds) NEC ventral surface ; etc

The following list of clinical terms are approximate synonyms, alternative descriptions, or common phrases that might be used by patients, healthcare providers, or medical coders to describe the same condition. These synonyms and related diagnosis terms are often used when searching for an ICD-10 code, especially when the exact medical terminology is unclear. Whether you're looking for lay terms, similar diagnosis names, or common language alternatives, this list can help guide you to the correct ICD-10 classification.

• Neoplasm of uncertain behavior of base of tongue
• Neoplasm of uncertain behavior of border of tongue
• Neoplasm of uncertain behavior of dorsal surface of tongue

Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.

They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.

CCSR Code: NEO072

Inpatient Default: Y - Yes, default inpatient assignment for principal diagnosis or first-listed diagnosis.

Outpatient Default: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.

• Ankyloglossia

a severe congenital restriction of tongue movement, resulting from fusion or adherence of the tongue to the floor of the mouth. in partial ankyloglossia (tongue-tie) the lingual frenum is abnormally short, or is attached too close to the tip of the tongue. omim: 106280

• Bluetongue

a reovirus infection, chiefly of sheep, characterized by a swollen blue tongue, catarrhal inflammation of upper respiratory and gastrointestinal tracts, and often by inflammation of sensitive laminae of the feet and coronet.

• Body Piercing

the perforation of an anatomical region for the wearing of jewelry.

• Electronic Nose

a device used to detect airborne odors, gases, flavors, volatile substances or vapors.

• Fasciculation

involuntary contraction of the muscle fibers innervated by a motor unit. fasciculations may be visualized as a muscle twitch or dimpling under the skin, but usually do not generate sufficient force to move a limb. they may represent a benign condition or occur as a manifestation of motor neuron disease or peripheral nervous system diseases. (adams et al., principles of neurology, 6th ed, p1294)

• Glossitis, Benign Migratory

an idiopathic disorder of the tongue characterized by the loss of filiform papillae leaving reddened areas of circinate macules bound by a white band. the lesions heal, then others erupt.

• Medicine, Chinese Traditional

a system of traditional medicine which is based on the beliefs and practices of the chinese culture.

• Oral Frenectomy

surgical procedures to release or remove abnormally short or tightly attached frenum (e.g., lingual frenum or labial frenum) associated with a pathological condition (e.g., tongue tie and lip tie).

• Pentastomida

a subclass of crustacea comprising the tongue worms which are obligatory parasites of reptiles, birds, and mammals including humans.

• Tongue

a muscular organ in the mouth that is covered with pink tissue called mucosa, tiny bumps called papillae, and thousands of taste buds. the tongue is anchored to the mouth and is vital for chewing, swallowing, and for speech.

• Tongue Diseases

diseases involving the tongue.

• Tongue Habits

acquired responses regularly manifested by tongue movement or positioning.

• Tongue Neoplasms

tumors or cancer of the tongue.

• Tongue, Fissured

the occurrence of of breaks or slits in the tissue of the dorsal surface of the tongue.

• Tongue, Hairy

a benign condition of the tongue characterized by hypertrophy of the filiform papillae that give the dorsum of the tongue a furry appearance. the color of the elongated papillae varies from yellowish white to brown or black, depending upon staining by substances such as tobacco, food, or drugs. (dorland, 27th ed)

Below are the ICD-9 codes that most closely match this ICD-10 code, based on the General Equivalence Mappings (GEMs). This ICD-10 to ICD-9 crosswalk tool is helpful for coders who need to reference legacy diagnosis codes for audits, historical claims, or approximate code comparisons.

ICD-9-CM: 235.1

Approximate Flag - The approximate mapping means this ICD-10 code does not have an exact ICD-9 equivalent. The matched code is the closest available option, but it may not fully capture the original diagnosis or clinical intent.

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.

Tongue Disorders

Your tongue helps you taste, swallow, and chew. You also use it to speak. Your tongue is made up of many muscles. The upper surface contains your taste buds.

Problems with the tongue include:

• Pain
• Swelling
• Changes in color or texture
• Abnormal movement or difficulty moving the tongue
• Taste problems

These problems can have many different causes. Treatment depends on the underlying problem.
