About coding secondary hyperhidrosis
The ICD-10-CM code for secondary hyperhidrosis is R61 (Generalized hyperhidrosis). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on R61.
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.
