Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to R61: its own notes plus those printed at Chapter 18. A note printed at a category, block or chapter applies to every code under it.

Applicable To

Conditions this code is used for: synonyms of the title or, for "other specified" codes, the conditions assigned to it. The list is not exhaustive.

  • Excessive sweating
  • Night sweats
  • Secondary hyperhidrosis

Excludes1

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

  • focal (primary) (secondary) hyperhidrosis (L74.5-)
  • Frey's syndrome (L74.52)
  • localized (primary) (secondary) hyperhidrosis (L74.5-)

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 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.

Clinical InformationClinical

  • Hyperhidrosis

    excessive sweating. in the localized type, the most frequent sites are the palms, soles, axillae, inguinal folds, and the perineal area. its chief cause is thought to be emotional. generalized hyperhidrosis may be induced by a hot, humid environment, by fever, or by vigorous exercise.

Patient EducationClinical

Sweat

Sweat is a clear, salty liquid produced by glands in your skin. Sweating is how your body cools itself. You sweat mainly under your arms and on your feet and palms. When sweat mixes with bacteria on your skin, it can cause a smell. Bathing regularly and using antiperspirants or deodorants can help control the odor.

Questions About R61Overview

What is the ICD-10 code for generalized hyperhidrosis?

The ICD-10-CM code for generalized hyperhidrosis is R61. It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is R61 (Generalized hyperhidrosis) a billable code?

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

What MS-DRG does R61 group to?

When generalized hyperhidrosis is the principal diagnosis on an inpatient stay, it groups to MS-DRG 607, 606, with relative weights from 0.8772 to 1.5721 depending on complications. Higher weights mean higher Medicare reimbursement.

Can R61 be a principal diagnosis?

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

Can R61 be reported with a code from L74.5?

Not as a rule. The Excludes1 note on R61 lists "focal (primary) (secondary) hyperhidrosis (L74.5-)". 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).
