Male Breast Cancer

Although breast cancer is much more common in women, men can get it too. It happens most often to men between the ages of 60 and 70.

Breast lumps usually aren't cancer. However, most men with breast cancer have lumps. Other breast symptoms can include

• Dimpled or puckered skin
• A red, scaly nipple or skin
• Fluid discharge

Risk factors for male breast cancer include exposure to radiation, a family history of breast cancer, and having high estrogen levels, which can happen with diseases like cirrhosis or Klinefelter's syndrome.

Treatment for male breast cancer is usually a mastectomy, which is surgery to remove the breast. Other treatments include radiation, chemotherapy and/or hormone therapy.

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.
