Generalized hyperhidrosis
In General symptoms and signs (R50-R69), chapter 18: Symptoms, Signs and Abnormal Clinical and Laboratory Findings
- R61 is billable and valid on claims for FY 2027. If the record has more detail, check the other codes under R50-R69 below.
- As a secondary diagnosis it is not a CC or MCC, so it doesn't raise the MS-DRG payment.
- Doesn't count toward a Medicare Advantage risk score (no HCC in V28).
- AHRQ's Chronic Condition Indicator classes it as not chronic (an acute or short-term condition).
Also indexed as: Diaphoresis; Excess, secretion, sweat; Excess, sweating; Hyperhidrosis; Hyperhidrosis, generalized; Hyperhidrosis, secondary; Night, sweats; Sweat, night; Sweating

R61 MS-DRGs

About the condition
Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.
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.
