D02 is a non-billable ICD-10-CM category code for carcinoma in situ of middle ear and respiratory system, so it cannot be submitted on claims. Use a more specific code from this category instead, such as D02.0, D02.1, D02.20, and D02.21.

Specific Coding for Carcinoma in situ of middle ear and respiratory systemOverview

Non-specific codes like D02 require more characters. Use one of these billable codes instead:

  • Use D02.0 for Carcinoma in situ of larynx

  • Use D02.1 for Carcinoma in situ of trachea

  • D02.2 for Carcinoma in situ of bronchus and lung

  • Use D02.20 for Carcinoma in situ of unspecified bronchus and lung

  • Use D02.21 for Carcinoma in situ of right bronchus and lung

  • Use D02.22 for Carcinoma in situ of left bronchus and lung

  • Use D02.3 for Carcinoma in situ of other parts of respiratory system

  • Use D02.4 for Carcinoma in situ of respiratory system, unspecified

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to D02: its own notes plus those printed at block D00-D09 and Chapter 2. A note printed at a category, block or chapter applies to every code under it.

Includes

Further defines, or gives examples of, the content of the category.

From Block D00-D09 In situ neoplasms applies to 106 codes
  • Bowen's disease
  • erythroplasia
  • grade III intraepithelial neoplasia
  • Queyrat's erythroplasia

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

Use Additional Code

Add a second code, after this one, to fully describe the condition.

  • 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)

Notes

General instructions on how these codes are used.

From Chapter 2 (C00-D49) Neoplasms applies to 1,730 codes
  • Functional activity
  • All neoplasms are classified in this chapter, whether they are functionally active or not. An additional code from Chapter 4 may be used, to identify functional activity associated with any neoplasm.
  • Morphology [Histology]
  • Chapter 2 classifies neoplasms primarily by site (topography), with broad groupings for behavior, malignant, in situ, benign, etc. The Table of Neoplasms should be used to identify the correct topography code. In a few cases, such as for malignant melanoma and certain neuroendocrine tumors, the morphology (histologic type) is included in the category and codes.
  • Primary malignant neoplasms overlapping site boundaries
  • A primary malignant neoplasm that overlaps two or more contiguous (next to each other) sites should be classified to the subcategory/code .8 ('overlapping lesion'), unless the combination is specifically indexed elsewhere. For multiple neoplasms of the same site that are not contiguous, such as tumors in different quadrants of the same breast, codes for each site should be assigned.
  • Malignant neoplasm of ectopic tissue
  • Malignant neoplasms of ectopic tissue are to be coded to the site mentioned, e.g., ectopic pancreatic malignant neoplasms are coded to pancreas, unspecified (C25.9).

Patient EducationClinical

Cancer

Cancer is not just one disease but many diseases. Cancer begins in your cells, which are the building blocks of your body. Usually, your body forms new cells as needed, replacing old cells that die. Sometimes this process goes wrong. New cells grow even when you don't need them, and old cells don't die when they should.

Questions About D02Overview

What is the ICD-10 code for carcinoma in situ of middle ear and respiratory system?

D02 is the ICD-10-CM category for carcinoma in situ of middle ear and respiratory system, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is D02 (Carcinoma in situ of middle ear and respiratory system) a billable code?

No. This is a category header that groups the codes for carcinoma in situ of middle ear and respiratory system, and headers cannot be submitted on claims. Claims for carcinoma in situ of middle ear and respiratory system need a more specific code from this category, such as D02.0, D02.1, and D02.20.

Can D02 be reported with a code from D03?

Not as a rule. The Excludes1 note on D02 lists "melanoma in situ (D03.-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).

Does D02 need an additional code?

When the condition applies, yes. The Use Additional Code note reads: 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 listed in the Instructional Notes section. The additional code is reported after D02.
