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 R11.13Overview

What is the ICD-10 code for vomiting of fecal matter?

The ICD-10-CM code for vomiting of fecal matter is R11.13 (sometimes written as R1113). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is R11.13 (Vomiting) a billable code?

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

What MS-DRG does R11.13 group to?

When vomiting of fecal matter is the principal diagnosis on an inpatient stay, it groups to MS-DRG 394, 395, 393, with relative weights from 0.6379 to 1.5877 depending on complications. Higher weights mean higher Medicare reimbursement.

Can R11.13 be a principal diagnosis?

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

Can R11.13 be reported with a code from G43.A?

Not as a rule. The Excludes1 note at R11, which applies to R11.13, lists "cyclical vomiting associated with migraine (G43.A-)". 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).
