D27Benign neoplasm of ovary

Non-billable headerICD-10-CM

D27 is a non-billable header ICD-10-CM code for benign neoplasm of ovary. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

  • corpus albicans cyst (N83.2-)
  • corpus luteum cyst (N83.1-)
  • endometrial cyst (N80.1-)
  • follicular (atretic) cyst (N83.0-)
  • graafian follicle cyst (N83.0-)
  • ovarian cyst NEC (N83.2-)
  • ovarian retention cyst (N83.2-)

Use additional code

Add a secondary code to capture the detail described below.

  • code to identify any functional activity.

Other codes that can never be billed with D27

These codes carry an Excludes1 note pointing at D27. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D27 alone.

  • N83.2Other and unspecified ovarian cysts
  • D35Benign neoplasm of other and unspecified endocrine glands

Risk adjustment

D27 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead D27

3 child codes. Green means billable.
