ICD Coding
  • ICD-9-CM Codes: 183.0, 236.2
  • ICD-10-AM Codes: C56, D39.1
Brief description

This is a primary cancer of the ovary.  Primary means that the cancer arose in the ovary and did not arrive secondarily from another body site.

Confirming the diagnosis

Information on histology (from biopsy or surgery) is required to confirm the diagnosis and apply the SOP.  There are SOP factors specific to epithelial and mucinous ovarian cancers only, so information on specific tumour type will be required to apply those factors.

The relevant medical specialist is a gynaecologist or gynaecological oncologist.

Additional diagnoses covered by SOP

  • Carcinoma-in-situ of the ovary
  • Epithelial cell cancer of the ovary
  • Germ cell cancer of the ovary
  • Neoplasm of the ovary with borderline potential
  • Stromal cell cancer of the ovary
Conditions excluded from SOP
  • Benign neoplasm of the ovary#
  • Carcinoid tumour of the ovary#
  • Hodgkin's lymphoma of the ovary*
  • Malignant neoplasm of the fallopian tube (primary)#
  • non-Hodgkin's lymphoma of the ovary*
  • soft tissue sarcoma of the ovary*
  • Secondary neoplasm of the ovary, code to primary site (commonly from sites such as breast, colon, gastric and pancreatic malignant neoplasms)

# non-SOP condition 

Clinical onset

The clinical presentation is variable.  There may be non-specific symptoms such as pelvic or abdominal pain, bloating, or gastrointestinal symptoms.  A mass may be identified incidentally on imaging or examination.  There may be an acute presentation with bowel obstruction or pleural effusion. 

Clinical worsening

The only SOP worsening factor is for inability to obtain appropriate clinical management.  Appropriate management can vary substantially with each case.
