Chapter II
Neoplasms
(C00-D48)

Malignant neoplasms
(C00-C97)

Coding-Hint
Use additional code ( U85) , if desired, to identify resistance, non-responsiveness and refractive properties of the neoplasm to antineoplastic drugs.

Malignant neoplasms, stated or presumed to be primary, of specified sites, except of lymphoid, haematopoietic and related tissue
(C00-C75)

Malignant neoplasms of digestive organs
(C15-C26)

C15 Malignant neoplasm of oesophagus

Note:

Two alternative subclassifications are given:

  • .0-.2 by anatomical description

  • .3-.5 by thirds

This departure from the principle that categories should be mutually exclusive is deliberate, since both forms of terminology are in use but the resulting anatomical divisions are not analogous.

C15.2 Abdominal part of oesophagus
