Lewy body dementia (LBD) is not a single disorder but a spectrum of disorders involving disturbances of movement, cognition, behavior, sleep and autonomic function.

When diagnosing Lewy body dementias, please use the following ICD-9 code combinations:

* dementia with Lewy bodies (DLB)

331.82 - "Dementia with Lewy bodies"

294.1x - "Dementia" with the 'x' determined by presence ("1") or absence ("0") of behavioral disturbance.

(NOTE: Not all insurance carriers process 294.1x codes the same way. Confer with a billing expert before using this code.)

* Parkinson's disease dementia (PDD)

331.82 - "DLB, parkinsonism with dementia, Lewy body dementia, Lewy body disease"

332.0 - "Parkinson's disease"

294.1x - "Dementia" with the 'x' determined by presence ("1") or absence ("0") of behavioral disturbance.

(NOTE: Not all insurance carriers process 294.1x codes the same way. Confer with a billing expert before using this code.)
