D21

Other benign neoplasms of connective and other soft tissue

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 8 more specific codes instead:

  • D21.0 Benign neoplasm of connective and other soft tissue of head, face and neck
  • D21.1 Benign neoplasm of connective and other soft tissue of upper limb, including shoulder (also a header)
  • D21.2 Benign neoplasm of connective and other soft tissue of lower limb, including hip (also a header)
  • D21.3 Benign neoplasm of connective and other soft tissue of thorax
  • D21.4 Benign neoplasm of connective and other soft tissue of abdomen
  • D21.5 Benign neoplasm of connective and other soft tissue of pelvis
  • D21.6 Benign neoplasm of connective and other soft tissue of trunk, unspecified
  • D21.9 Benign neoplasm of connective and other soft tissue, 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.
