Carcinoma in situ of middle ear and respiratory system (D02)
ICD-10 code D02 covers carcinoma in situ affecting the middle ear and various parts of the respiratory system, including the larynx, trachea, bronchus, lung, and other related areas. These codes specifically identify early-stage cancers that have not yet invaded deeper tissues.
The section includes detailed subcodes such as D02.0 for carcinoma in situ of the larynx, which is also known by terms like neoplasm of the false vocal cord or carcinoma in situ of the vocal cord. Codes D02.1 and D02.2 indicate carcinoma in situ of the trachea and bronchus/lung, respectively. For instance, D02.21 specifies carcinoma in situ in the right bronchus and lung, while D02.22 refers to the left side. Other codes like D02.3 target carcinoma in situ in other respiratory areas such as the middle ear, nasal cavity, or pleura. If the exact site is unclear, D02.4 or D02.20 identify unspecified locations within the respiratory system. These distinctions guide accurate documentation and treatment planning using the ICD-10 code for carcinoma in situ of the respiratory system and middle ear.

Instructional Notations
Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
- code to identify:
- exposure to environmental tobacco smoke Z77.22
- exposure to tobacco smoke in the perinatal period P96.81
- history of tobacco dependence Z87.891
- occupational exposure to environmental tobacco smoke Z57.31
- tobacco dependence F17
- tobacco use Z72.0
Type 1 Excludes
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.
- melanoma in situ D03
Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Epiglottis
A thin leaf-shaped cartilage that is covered with LARYNGEAL MUCOSA and situated posterior to the root of the tongue and HYOID BONE. During swallowing, the epiglottis folds back over the larynx inlet thus prevents foods from entering the airway.
Eustachian Tube
A narrow passageway that connects the upper part of the throat to the TYMPANIC CAVITY.
Glottis
The vocal apparatus of the larynx, situated in the middle section of the larynx. Glottis consists of the VOCAL FOLDS and an opening (rima glottidis) between the folds.
