About coding senile dysfunction
The ICD-10-CM code for senile dysfunction is R54 (Age-related physical debility).
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.
Don't confuse with (Excludes1 for R54)
