Code Classification

  • Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified
    • General symptoms and signs
      • Generalized hyperhidrosis

R61 is a billable diagnosis code used to specify a medical diagnosis of generalized hyperhidrosis. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

According to ICD-10-CM guidelines this code should not to be used as a principal diagnosis code when a related definitive diagnosis has been established.

Clinical Classification

Clinical Information

  • 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.
  • 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)
  • 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.
  • Parotid Neoplasms

    tumors or cancer of the parotid gland.
  • Sweating Fever

    a febrile response accompanied by diaphoresis.

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.

Inclusion Terms

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

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

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

Patient Education


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.

Sweating a lot is normal when it is hot or when you exercise, are anxious, or have a fever. It also happens during menopause. If you often sweat too much, it's called hyperhidrosis. Causes include thyroid or nervous system disorders, low blood sugar, or another health problem.

Sweating too little, anhidrosis, can be life-threatening because your body can overheat. Causes of anhidrosis include dehydration, burns, and some skin and nerve disorders.

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
