2021 ICD-10-CM Codes R00-R99: Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified

1. ICD-10-CM Codes
›
2. Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified R00-R99

• 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.

  ICD-10-CM Diagnosis Code R00

  Abnormalities of heart beat

  2016 2017 2018 2019 2020 2021 Non-Billable/Non-Specific Code
  Type 1 Excludes
  • abnormalities originating in the perinatal period (P29.1-)

  ICD-10-CM Diagnosis Code R94

  Abnormal results of function studies

  2016 2017 2018 2019 2020 2021 Non-Billable/Non-Specific Code
  Includes
  • abnormal results of radionuclide [radioisotope] uptake studies
  • abnormal results of scintigraphy
  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 Help

A type 2 excludes note represents "not included here". A type 2 excludes note indicates that the condition excluded is not part of the condition it is excluded from but a patient may have both conditions at the same time. When a type 2 excludes note appears under a code it is acceptable to use both the code ( R00-R99 ) and the excluded code together.
