Late effect of contusion

This code signifies a persistent health problem or complication that arises months or years after an initial contusion has healed. It describes a residual condition directly attributable to the original blunt force trauma, rather than the acute injury itself. Examples include chronic pain, nerve damage, or functional limitations resulting from the initial bruising.

Use this code when documentation clearly links a current, ongoing condition to a past contusion. This applies when the acute phase of the contusion has passed, and the patient is experiencing a long-term sequela. Documentation should specify the nature of the late effect and its causal relationship to the previous contusion.

• Always sequence this code after the code identifying the specific late effect (e.g., chronic pain, scar formation).
• Ensure the medical record explicitly states the connection between the current condition and a past contusion.
• Do not use for acute contusions; those are coded with codes from the 920-924 range.
