Information for Patients


Blood Disorders

Also called: Hematologic diseases

Your blood is living tissue made up of liquid and solids. The liquid part, called plasma, is made of water, salts and protein. Over half of your blood is plasma. The solid part of your blood contains red blood cells, white blood cells and platelets.

Blood disorders affect one or more parts of the blood and prevent your blood from doing its job. They can be acute or chronic. Many blood disorders are inherited. Other causes include other diseases, side effects of medicines, and a lack of certain nutrients in your diet.

Types of blood disorders include

  • Platelet disorders, excessive clotting, and bleeding problems, which affect how your blood clots
  • Anemia, which happens when your blood does not carry enough oxygen to the rest of your body
  • Cancers of the blood, such as leukemia and myeloma
  • Eosinophilic disorders, which are problems with one type of white blood cell.
  • Blood differential
  • Blood smear
  • CBC
  • Hematocrit
  • Hemoglobin
  • Hemoglobin electrophoresis
  • Hemolytic disease of the newborn
  • Hyperviscosity - newborn
  • Low white blood cell count and cancer
  • Neutropenia - infants
  • RBC count
  • RBC indices
  • Serum free hemoglobin test
  • WBC count

Health Problems in Pregnancy

Every pregnancy has some risk of problems. The causes can be conditions you already have or conditions you develop. They also include being pregnant with more than one baby, previous problem pregnancies, or being over age 35. They can affect your health and the health of your baby.

If you have a chronic condition, you should talk to your health care provider about how to minimize your risk before you get pregnant. Once you are pregnant, you may need a health care team to monitor your pregnancy. Examples of common conditions that can complicate a pregnancy include

  • Heart disease
  • High blood pressure
  • Kidney problems
  • Autoimmune disorders
  • Sexually transmitted diseases
  • Diabetes
  • Cancer
  • Infections

Other conditions that can make pregnancy risky can happen while you are pregnant - for example, gestational diabetes and Rh incompatibility. Good prenatal care can help detect and treat them.

Some discomforts, like nausea, back pain, and fatigue, are common during pregnancy. Sometimes it is hard to know what is normal. Call your doctor or midwife if something is bothering or worrying you.

  • Bed rest during pregnancy
  • Hydramnios
  • Hyperemesis gravidarum
  • Insufficient cervix
  • Morning sickness
  • Morning sickness
  • Placenta abruptio

ICD-9 Footnotes

General Equivalence Map Definitions
The ICD-9 and ICD-10 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.
