Health Screening

Also called: Screening tests

Screenings are tests that look for diseases before you have symptoms. Screening tests can find diseases early, when they're easier to treat. You can get some screenings in your doctor's office. Others need special equipment, so you may need to go to a different office or clinic.

Some conditions that doctors commonly screen for include

  • Breast cancer and cervical cancer in women
  • Colorectal cancer
  • Diabetes
  • High blood pressure
  • High cholesterol
  • Osteoporosis
  • Overweight and obesity
  • Prostate cancer in men

Which tests you need depends on your age, your sex, your family history, and whether you have risk factors for certain diseases. After a screening test, ask when you will get the results and whom to talk to about them.

Osteoporosis

Osteoporosis is a disease that thins and weakens the bones. Your bones become fragile and break easily, especially the bones in the hip, spine, and wrist. In the United States, millions of people either already have osteoporosis or are at high risk due to low bone mass.

Anyone can develop osteoporosis, but it is more common in older women. Risk factors include

  • Getting older
  • Being small and thin
  • Having a family history of osteoporosis
  • Taking certain medicines
  • Being a white or Asian woman
  • Having low bone density

Osteoporosis is a silent disease. You might not know you have it until you break a bone. A bone mineral density test is the best way to check your bone health.

To keep bones strong, eat a diet rich in calcium and vitamin D, exercise, and do not smoke. If needed, medicines can also help. It is also important to try to avoid falling down. Falls are the number one cause of fractures in older adults.

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.
