A surgical specialty office documents follow-up for sequela of a traumatic brain injury with residual cognitive deficit. Which concept should guide diagnosis coding?
Select an answer to reveal the explanation.
Short Explanation
Sequela is the “aftershock” chapter—old injury, lingering problem. Clinic follow-up for residual cognitive deficit after TBI is not a fresh initial-encounter reboot; code the residual as sequela of the prior injury.
Full Explanation
ICD-10-CM distinguishes acute injury episodes from sequela (late effects). When documentation describes residual deficits from a prior traumatic brain injury under follow-up care, sequela coding concepts apply rather than repeated initial-encounter acute injury coding. Personal-history codes are not used in place of active residual conditions being managed.
