Clinical InformationClinical
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: 106280Bluetongue

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

(dorland, 27th ed)Granular Cell Tumor
unusual tumor affecting any site of the body, but most often encountered in the head and neck. considerable debate has surrounded the histogenesis of this neoplasm; however, it is considered to be a myoblastoma of, usually, a benign nature. it affects women more often than men. when it develops beneath the epidermis or mucous membrane, it can lead to proliferation of the squamous cells and mimic squamous cell carcinoma.

Patient EducationClinical
Benign Tumors
Tumors are abnormal growths in your body. They can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. Benign tumors grow only in one place. They cannot spread or invade other parts of your body. Even so, they can be dangerous if they press on vital organs, such as your brain.

Questions About D10.1Overview
Is D10.1 (Benign neoplasm of mouth and pharynx) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report benign neoplasm of tongue on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does D10.1 group to?
When benign neoplasm of tongue is the principal diagnosis on an inpatient stay, it groups to MS-DRG 157, 158, 159, with relative weights from 0.7085 to 1.7168 depending on complications. Higher weights mean higher Medicare reimbursement.
What is the ICD-9 equivalent of D10.1?
Under the General Equivalence Mappings, benign neoplasm of tongue converts to ICD-9-CM 210.1 (benign neoplasm tongue). The mapping is a direct match.
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.
