Z87.820Personal history of traumatic brain injury

Z87.820 is the ICD-10-CM diagnosis code for personal history of traumatic brain injury. It belongs to category Z87 (personal history of other diseases and conditions), block Z77-Z99 (persons with potential health hazards related to family and personal history and certain conditions influencing health status) and chapter 21 (factors influencing health status and contact with health services). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within Z87.82 (personal history of other (healed) physical injury and trauma), Z87.820 is specifically for personal history of traumatic brain injury. Related codes cover retained foreign body fully removed (Z87.821) and other (healed) physical injury and trauma (Z87.828).

Don't report Z87.820 together with the conditions in its Excludes1 note: personal history of transient ischemic attack (TIA), and cerebral infarction without residual deficits (Z86.73).

Code first: any follow-up examination after treatment (Z09).

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.

It is not acceptable as the principal diagnosis for an inpatient stay; it may be reported as a secondary diagnosis.

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as V15.52 (personal history of traumatic brain injury).
