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.
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

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 D14.0Overview
Is D14.0 (Benign neoplasm of middle ear and respiratory system) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report benign neoplasm of middle ear, nasal cavity and accessory sinuses on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does D14.0 group to?
When benign neoplasm of middle ear, nasal cavity and accessory sinuses is the principal diagnosis on an inpatient stay, it groups to MS-DRG 154, 155, 156, with relative weights from 0.6911 to 1.5635 depending on complications. Higher weights mean higher Medicare reimbursement.
What is the ICD-9 equivalent of D14.0?
Under the General Equivalence Mappings, benign neoplasm of middle ear, nasal cavity and accessory sinuses converts to ICD-9-CM 212.0 (ben neo nasal cav/sinus). 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.
