About coding traumatic brain injury screening
The ICD-10-CM code for traumatic brain injury screening is Z13.850 (Encounter for screening for traumatic brain injury).
Within Z13.85 (encounter for screening for nervous system disorders), Z13.850 is specifically for encounter for screening for traumatic brain injury. Related codes cover other nervous system disorders (Z13.858).
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.
