Generalized hyperhidrosis (R61) ICD-10-CM
The R61 code range covers generalized hyperhidrosis with 1 ICD-10-CM diagnosis codes. 1 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Excessive sweating
- Night sweats
- Secondary hyperhidrosis
Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
- , if applicable, menopausal and female climacteric states N95.1
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the R61 range.
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.
Parotid Neoplasms
Tumors or cancer of the PAROTID GLAND.
Sweating
The process of exocrine secretion of the SWEAT GLANDS, including the aqueous sweat from the ECCRINE GLANDS and the complex viscous fluids of the APOCRINE GLANDS.
Sweating Sickness
A clinical condition characterized by fever and profuse sweating and associated with high mortality. It occurred in epidemic form five times in the fifteenth and sixteenth centuries in England, first in 1485 and last in 1551, specially during the summer and early autumn, attacking the relatively affluent adult male population. The etiology was unknown.
Sweating, Gustatory
An autonomic disorder characterized by excessive sweating of the forehead, upper lip, perioral region, or sternum subsequent to gustatory stimuli. The auriculotemporal syndrome features facial flushing or sweating limited to the distribution of the auriculotemporal nerve and may develop after trauma to the parotid gland, in association with PAROTID NEOPLASMS, or following their surgical removal. (From Ann Neurol 1997 Dec;42(6):973-5)
About the R61 Code Range
ICD-10 code R61 is used to identify generalized hyperhidrosis, a condition characterized by excessive sweating over large areas of the body. This code covers various patterns and causes of abnormal sweating beyond localized areas.
The ICD-10 code for generalized hyperhidrosis includes a range of sweating symptoms such as hot sweats, night sweats, clammy sweat, and asymmetrical sweating. It encompasses conditions like drug-induced hyperhidrosis, menopausal hyperhidrosis, and hyperhidrosis linked with neurological or autonomic disorders. Common synonyms you may encounter include "excessive sweating," "sweating attack," and "idiopathic diffuse hyperhidrosis." Additionally, R61 captures hyperhidrosis associated with diseases like AIDS and may reflect related symptoms such as sweating fever or gustatory hyperhidrosis. This broad code is essential for medical coders and professionals to accurately document and differentiate generalized excessive sweating, aiding in proper diagnosis and care management.
