About D02.2

D02.2 is the ICD-10-CM diagnosis code for carcinoma in situ of bronchus and lung. It belongs to category D02 (carcinoma in situ of middle ear and respiratory system), block D00-D09 (in situ neoplasms) and chapter 2 (neoplasms). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within D02 (carcinoma in situ of middle ear and respiratory system), D02.2 is specifically for carcinoma in situ of bronchus and lung. Related codes cover larynx (D02.0), trachea (D02.1), other parts of respiratory system (D02.3) and respiratory system, unspecified (D02.4).

To report this condition, pick the subcode that matches the documentation: D02.20 (lung), D02.21 (lung) and D02.22 (lung).

Use an additional 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.-) and 1 more.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
