  • R00-R99
    2020 ICD-10-CM Range R00-R99

    Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified

    Note
    • This chapter includes symptoms, signs, abnormal results of clinical or other investigative procedures, and ill-defined conditions regarding which no diagnosis classifiable elsewhere is recorded.
    • Signs and symptoms that point rather definitely to a given diagnosis have been assigned to a category in other chapters of the classification. In general, categories in this chapter include the less well-defined conditions and symptoms that, without the necessary study of the case to establish a final diagnosis, point perhaps equally to two or more diseases or to two or more systems of the body. Practically all categories in the chapter could be designated 'not otherwise specified', 'unknown etiology' or 'transient'. The Alphabetical Index should be consulted to determine which symptoms and signs are to be allocated here and which to other chapters. The residual subcategories, numbered .8, are generally provided for other relevant symptoms that cannot be allocated elsewhere in the classification.
    • The conditions and signs or symptoms included in categories R00-R94 consist of:
    • (a) cases for which no more specific diagnosis can be made even after all the facts bearing on the case have been investigated;
    • (b) signs or symptoms existing at the time of initial encounter that proved to be transient and whose causes could not be determined;
    • (c) provisional diagnosis in a patient who failed to return for further investigation or care;
    • (d) cases referred elsewhere for investigation or treatment before the diagnosis was made;
    • (e) cases in which a more precise diagnosis was not available for any other reason;
    • (f) certain symptoms, for which supplementary information is provided, that represent important problems in medical care in their own right.
    Type 2 Excludes
    • abnormal findings on antenatal screening of mother (O28.-)
    • certain conditions originating in the perinatal period (P04-P96)
    • signs and symptoms classified in the body system chapters
    • signs and symptoms of breast (N63, N64.5)
    Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified

    Abnormal glucose
Approximate Synonyms
  • Abnormal glucose measurement
  • Abnormal glucose tolerance test
  • Blood glucose abnormal
  • Elevated hemoglobin a1c measurement
  • High hemoglobin a1c level
  • Prediabetes
Clinical Information
  • A condition referring to fasting plasma glucose levels being less than 140 mg per deciliter while the plasma glucose levels after a glucose tolerance test being more than 200 mg per deciliter at 30, 60, or 90 minutes. It is observed in patients with diabetes mellitus. Other causes include immune disorders, genetic syndromes, and cirrhosis.
  • A disorder characterized by an inability to properly metabolize glucose.
  • A pathological state in which blood glucose level is less than approximately 140 mg/100 ml of plasma at fasting, and above approximately 200 mg/100 ml plasma at 30-, 60-, or 90-minute during a glucose tolerance test. This condition is seen frequently in diabetes mellitus, but also occurs with other diseases and malnutrition.
  • Pre-diabetes means you have blood glucose levels that are higher than normal but not high enough to be called diabetes. Glucose comes from the foods you eat. Too much glucose in your blood can damage your body over time. If you have pre-diabetes, you are more likely to develop type 2 diabetes, heart disease, and stroke.most people with pre-diabetes don't have any symptoms. Your doctor can test your blood to find out if your blood glucose levels are higher than normal. If you are 45 years old or older, your doctor may recommend that you be tested for pre-diabetes, especially if you are overweight.losing weight - at least 5 to 10 percent of your starting weight - can prevent or delay diabetes or even reverse pre-diabetes. That's 10 to 20 pounds for someone who weighs 200 pounds. You can lose weight by cutting down on the amount of calories and fat you eat and being physically active at least 30 minutes a day. Being physically active makes your body's insulin work better. Your doctor may also prescribe medicine to help control the amount of glucose in your blood.
  • State of latent impairment of carbohydrate metabolism in which the criteria for diabetes mellitus are not all satisfied; sometimes controllable by diet alone; called also impaired glucose tolerance and impaired fasting glucose.
  • The time period before the development of symptomatic diabetes. For example, certain risk factors can be observed in subjects who subsequently develop insulin resistance as in type 2 diabetes (diabetes mellitus, type 2).
