About coding fall
The ICD-10-CM code for fall is W19.XXXA (Unspecified fall, initial encounter). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on W19.XXXA.
It is also searched as fall risk.
The 7th character "A" means initial encounter: use it while the patient is receiving active treatment for the condition.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
