R89 is a non-billable ICD-10-CM category code for abnormal findings in specimens from other organs, systems and tissues, so it cannot be submitted on claims. Use a more specific code from this category instead, such as R89.0, R89.1, R89.2, and R89.3. As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established.

Specific Coding for Abnormal findings in specimens from oth org/tissOverview

Non-specific codes like R89 require more characters. Use one of these billable codes instead:

  • Use R89.0 for Abnormal level of enzymes in specimens from other organs, systems and tissues

  • Use R89.1 for Abnormal level of hormones in specimens from other organs, systems and tissues

  • Use R89.2 for Abnormal level of other drugs, medicaments and biological substances in specimens from other organs, systems and tissues

  • Use R89.3 for Abnormal level of substances chiefly nonmedicinal as to source in specimens from other organs, systems and tissues

  • Use R89.4 for Abnormal immunological findings in specimens from other organs, systems and tissues

  • Use R89.5 for Abnormal microbiological findings in specimens from other organs, systems and tissues

  • Use R89.6 for Abnormal cytological findings in specimens from other organs, systems and tissues

  • Use R89.7 for Abnormal histological findings in specimens from other organs, systems and tissues

  • Use R89.8 for Other abnormal findings in specimens from other organs, systems and tissues

  • Use R89.9 for Unspecified abnormal finding in specimens from other organs, systems and tissues

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to R89: its own notes plus those printed at block R83-R89 and Chapter 18. A note printed at a category, block or chapter applies to every code under it.

Includes

Further defines, or gives examples of, the content of the category.

  • abnormal findings in nipple discharge
  • abnormal findings in synovial fluid
  • abnormal findings in wound secretions

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

From Block R83-R89 Abnormal findings on examination of other body fluids, substances and tissues, without diagnosis applies to 93 codes
  • abnormal findings on antenatal screening of mother (O28.-)
  • diagnostic abnormal findings classified elsewhere - see Alphabetical Index

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Block R83-R89 Abnormal findings on examination of other body fluids, substances and tissues, without diagnosis applies to 93 codes
  • abnormal findings on examination of blood, without diagnosis (R70-R79)
  • abnormal findings on examination of urine, without diagnosis (R80-R82)
  • abnormal tumor markers (R97.-)
From Chapter 18 (R00-R99) Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified applies to 774 codes
  • 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)

Notes

General instructions on how these codes are used.

From Chapter 18 (R00-R99) Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified applies to 774 codes
  • 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.

Questions About R89Overview

What is the ICD-10 code for abnormal findings in specimens from other organs, systems and tissues?

R89 is the ICD-10-CM category for abnormal findings in specimens from other organs, systems and tissues, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is R89 a billable code?

No. This is a category header that groups the codes for abnormal findings in specimens from other organs, systems and tissues, and headers cannot be submitted on claims. Claims for abnormal findings in specimens from other organs, systems and tissues need a more specific code from this category, such as R89.0, R89.1, and R89.2.

Can R89 be a principal diagnosis?

Use it with care. This is a symptom code, so once a definitive diagnosis explaining the abnormal findings in specimens from other organs, systems and tissues is established, that condition takes the principal position instead.

Can R89 be reported with a code from O28?

Not as a rule. The Excludes1 note at block R83-R89, which applies to R89, lists "abnormal findings on antenatal screening of mother (O28.-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
