Contusion of right thumb without damage to nail, sequela

This code describes a healed injury to the right thumb, specifically a bruise, where the nail itself was not damaged. It indicates that the initial injury has resolved, but there are lasting effects or complications from that original contusion.

Apply this code when documenting a patient presenting with a current condition directly attributable to a past contusion of the right thumb, where the nail was not involved. This is appropriate for follow-up encounters addressing residual pain, stiffness, or other chronic issues stemming from the original bruise.

• Ensure documentation clearly links the current symptoms to a previously sustained right thumb contusion.
• This code requires a seventh character "S" for sequela, indicating a late effect.
• Do not use for acute injuries; refer to the appropriate acute contusion codes.
