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 R23.2Overview

What is the ICD-10 code for flushing?

The ICD-10-CM code for flushing is R23.2 (sometimes written as R232). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is R23.2 (Other skin changes) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report flushing on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does R23.2 group to?

When flushing is the principal diagnosis on an inpatient stay, it groups to MS-DRG 948, 947, with relative weights from 0.7833 to 1.2608 depending on complications. Higher weights mean higher Medicare reimbursement.

Can R23.2 be a principal diagnosis?

Use it with care. This is a symptom code, so once a definitive diagnosis explaining the flushing is established, that condition takes the principal position instead.

What is coded first with R23.2?

The Code First note reads: if applicable, menopausal and female climacteric states (N95.1). When one of these applies, it is sequenced before R23.2.
