About coding senile degeneration
The ICD-10-CM code for senile degeneration is R54 (Age-related physical debility). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R54.
Don't report R54 together with the conditions in its Excludes1 note: age-related cognitive decline (R41.81), sarcopenia (M62.84), senile psychosis (F03.-) and senility NOS (R41.81).
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 884 (Organic Disturbances and Intellectual Disability, relative weight 1.6001), in MDC 19 (Mental Diseases and Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
