S99.811S
ICD-10-CMThis code signifies a long-term complication or residual effect stemming from a past injury to the right ankle, where the specific nature of the sequela is documented but does not fit into more specific categories. It indicates that the original acute injury has resolved, but its lasting impact on the right ankle is still present and requires ongoing management or documentation.
This code is appropriate for documenting chronic pain, stiffness, instability, or other persistent issues in the right ankle that are directly attributable to a previous injury, after the initial healing period has passed. It should be used when the specific sequela is known and documented, but there isn't a more precise ICD-10-CM code for that particular long-term effect.
