D49

Neoplasms of unspecified behavior

Not billableICD-10-CM diagnosis code.

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 10 more specific codes instead:

  • D49.0 Neoplasm of unspecified behavior of digestive system
  • D49.1 Neoplasm of unspecified behavior of respiratory system
  • D49.2 Neoplasm of unspecified behavior of bone, soft tissue, and skin
  • D49.3 Neoplasm of unspecified behavior of breast
  • D49.4 Neoplasm of unspecified behavior of bladder
  • D49.5 Neoplasm of unspecified behavior of other genitourinary organs (also a header)
  • D49.6 Neoplasm of unspecified behavior of brain
  • D49.7 Neoplasm of unspecified behavior of endocrine glands and other parts of nervous system
  • D49.8 Neoplasm of unspecified behavior of other specified sites (also a header)
  • D49.9 Neoplasm of unspecified behavior of unspecified site

What has happened to this code

Every change the publisher made, from 2012 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.
