D43

Neoplasm of uncertain behavior of brain and central nervous system

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 7 more specific codes instead:

  • D43.0 Neoplasm of uncertain behavior of brain, supratentorial
  • D43.1 Neoplasm of uncertain behavior of brain, infratentorial
  • D43.2 Neoplasm of uncertain behavior of brain, unspecified
  • D43.3 Neoplasm of uncertain behavior of cranial nerves
  • D43.4 Neoplasm of uncertain behavior of spinal cord
  • D43.8 Neoplasm of uncertain behavior of other specified parts of central nervous system
  • D43.9 Neoplasm of uncertain behavior of central nervous system, unspecified

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.

  1. FY2012 Added to the draft code set draft Neoplasm of uncertain behavior of brain and central nervous system

Official coding rules

Published by CDC for FY2027. A rule attached to a category binds every code beneath it, so the rules inherited from this code's ancestors are shown with the code they come from.

This code

Excludes1 - never coded here

  • neoplasm of uncertain behavior of peripheral nerves and autonomic nervous system (D48.2)

Inherited from the D37-D48 section Neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes (D37-D48)

Excludes1 - never coded here

  • neoplasms of unspecified behavior (D49.-)

Note

  • Categories D37-D44, and D48 classify by site neoplasms of uncertain behavior, i.e., histologic confirmation whether the neoplasm is malignant or benign cannot be made.
