    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.-)

Clinical Information
  • A disorder characterized by the sensation of marked discomfort, distress or agony.
  • An unpleasant sensation induced by noxious stimuli which are detected by nerve endings of nociceptive neurons.
  • Causing physical or psychological misery, pain or distress.
  • Intensely discomforting, distressful, or agonizing sensation associated with trauma or disease, with well-defined location, character, and timing.
  • Pain is a feeling triggered in the nervous system. Pain may be sharp or dull. It may come and go, or it may be constant. You may feel pain in one area of your body, such as your back, abdomen or chest or you may feel pain all over, such as when your muscles ache from the flu. Pain can be helpful in diagnosing a problem. Without pain, you might seriously hurt yourself without knowing it, or you might not realize you have a medical problem that needs treatment. Once you take care of the problem, pain usually goes away. However, sometimes pain goes on for weeks, months or even years. This is called chronic pain. Sometimes chronic pain is due to an ongoing cause, such as cancer or arthritis. Sometimes the cause is unknown. Fortunately, there are many ways to treat pain. Treatment varies depending on the cause of pain. pain relievers, acupuncture and sometimes surgery are helpful.
  • Pain that comes on quickly, can be severe, but lasts a relatively short time.
  • Physical suffering or distress, to hurt
  • Sensation of unpleasant feeling indicating potential or actual damage to some body structure felt all over, or throughout the body.
  • Severe pain of limited duration
  • The sensation of discomfort, distress, or agony, resulting from the stimulation of specialized nerve endings.
  • Unpleasant sensation induced by noxious stimuli and generally received by specialized nerve endings.
  • Unpleasant sensory and emotional experience arising from actual or potential tissue damage or described in terms of such damage (international association for the study of pain); sudden or slow onset of any intensity from mild to severe with an anticipated or predictable end and a duration of less than 6 months
  • Unpleasant sensory and emotional experience associated with actual or potential tissue damage.
