D19 is a non-billable ICD-10-CM category code for benign neoplasm of mesothelial tissue, so it cannot be submitted on claims. Use a more specific code from this category instead, such as D19.0, D19.1, D19.7, and D19.9.

Specific Coding for Benign neoplasm of mesothelial tissueOverview

Non-specific codes like D19 require more characters. Use one of these billable codes instead:

  • Use D19.0 for Benign neoplasm of mesothelial tissue of pleura

  • Use D19.1 for Benign neoplasm of mesothelial tissue of peritoneum

  • Use D19.7 for Benign neoplasm of mesothelial tissue of other sites

  • Use D19.9 for Benign neoplasm of mesothelial tissue, unspecified

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to D19: its own notes plus those printed at Chapter 2. A note printed at a category, block or chapter applies to every code under it.

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).

Excludes1 2

These codes carry an Excludes1 note naming D19: they are not reported together with it, unless the two conditions are unrelated.

  • D15 Benign neoplasm of other and unspecified intrathoracic organs
    benign neoplasm of mesothelial tissue (D19.-)
  • D20 Benign neoplasm of soft tissue of retroperitoneum and peritoneum
    benign neoplasm of mesothelial tissue (D19.-)

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 D19Overview

What is the ICD-10 code for benign neoplasm of mesothelial tissue?

D19 is the ICD-10-CM category for benign neoplasm of mesothelial tissue, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is D19 (Benign neoplasm of mesothelial tissue) a billable code?

No. This is a category header that groups the codes for benign neoplasm of mesothelial tissue, and headers cannot be submitted on claims. Claims for benign neoplasm of mesothelial tissue need a more specific code from this category, such as D19.0, D19.1, and D19.7.
