About R61

R61 is the ICD-10-CM diagnosis code for generalized hyperhidrosis. It belongs to block R50-R69 (general symptoms and signs) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Don't report R61 together with the conditions in its Excludes1 note: focal (primary) (secondary) hyperhidrosis (L74.5-), Frey's syndrome (L74.52) and localized (primary) (secondary) hyperhidrosis (L74.5-).

Code first: , if applicable, menopausal and female climacteric states (N95.1).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 606 (Minor Skin Disorders with MCC, relative weight 1.5728) and DRG 607 (Minor Skin Disorders without MCC, relative weight 0.8772), in MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 780.8 (generalized hyperhidrosis).
