Blister (nonthermal) of unspecified elbow, sequela

This code signifies a non-thermal blister that has developed on an unspecified elbow, indicating a residual effect or complication from a previous injury or condition. It represents a persistent or late-appearing manifestation rather than an acute injury.

Apply this code when documenting a patient presenting with a blister on the elbow that is not due to a burn, and the blister is a long-term consequence of an earlier, resolved issue. This is appropriate for follow-up visits where the blister is a sequela, not the initial injury itself.

• Ensure the documentation clearly states the blister is non-thermal and located on the elbow.
• Verify that the blister is a sequela, meaning it's a late effect or complication of a prior condition, not an acute event.
• Do not use for acute blisters or blisters due to burns; those require different codes.
