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 R87.623Overview

Is R87.623 (Abnormal cytological findings in specimens from vagina) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report high grade squamous intraepithelial lesion on cytologic smear of vagina (HGSIL) on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does R87.623 group to?

When high grade squamous intraepithelial lesion on cytologic smear of vagina (HGSIL) is the principal diagnosis on an inpatient stay, it groups to MS-DRG 742, 743, 760, 761, with relative weights from 0.7039 to 1.8448 depending on complications. Higher weights mean higher Medicare reimbursement.

Can R87.623 be a principal diagnosis?

Use it with care. This is a symptom code, so once a definitive diagnosis explaining the high grade squamous intraepithelial lesion on cytologic smear of vagina (HGSIL) is established, that condition takes the principal position instead.

Can R87.623 be reported with a code from R87.61?

Not as a rule. The Excludes1 note at R87.62, which applies to R87.623, lists "abnormal cytological findings in specimens from cervix uteri (R87.61-)". 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).

Does R87.623 need an additional code?

When the condition applies, yes. The Use Additional Code note at R87.62, which applies to R87.623, reads: code to identify acquired absence of uterus and cervix, if applicable (Z90.71-). The additional code is reported after R87.623.
