Ovarian Cysts

The ovaries are part of the female reproductive system. They produce a woman's eggs and make female hormones. Ovarian cysts are fluid-filled sacs in or on an ovary. They usually form during ovulation, when the ovary releases an egg. They are usually harmless and go away by themselves. Most women have them sometime during their lives.

Most ovarian cysts are small and don't cause symptoms. Women may not find out that they have them until they have a pelvic exam. If there are symptoms, they may include

  • Pressure
  • Bloating
  • Swelling
  • Pain in the lower abdomen, on the side where the cyst is

If your health care provider finds a cyst, you may be able to wait to see if it gets bigger. You may need surgery if you have pain, are past menopause, or if the cyst does not go away. If a cyst bursts or causes bleeding, you should get medical help right away. Birth control pills can help prevent new cysts.

Rarely, ovarian cysts can become cancerous. This risk increases as you get older.

A health problem that involves ovarian cysts is polycystic ovary syndrome (PCOS). Women with PCOS can have high levels of male hormones, irregular or no periods, and small ovarian cysts.

ICD-10 Footnotes

General Equivalence Map Definitions
The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

  • Approximate Flag - The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
  • No Map Flag - The no map flag indicates that a code in the source system is not linked to any code in the target system.
  • Combination Flag - The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.

Present on Admission
The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement.
