About coding falling problem
The ICD-10-CM code for falling problem is Z91.81 (History of falling).
Within Z91.8 (other specified personal risk factors, not elsewhere classified), Z91.81 is specifically for history of falling. Related codes cover personal history of military deployment (Z91.82), Wandering in diseases classified elsewhere (Z91.83), oral health risk factors (Z91.84), personal history of military service (Z91.85) and other specified personal risk factors, not elsewhere classified (Z91.89).
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 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
