Blister (nonthermal), right great toe, subsequent encounter

This code signifies a non-thermal blister located on the right great toe, indicating a subsequent encounter for this specific injury. It describes a localized collection of fluid under the skin, not caused by heat or cold, that is being treated or monitored after the initial presentation.

This code is appropriate for follow-up visits where a patient is receiving ongoing care for a blister on their right great toe, such as wound care, re-evaluation, or monitoring for healing. It should be used after the initial encounter for the blister has already been coded.

• Ensure the documentation specifies "subsequent encounter" for the blister.
• Verify the laterality (right) and specific digit (great toe) are clearly documented.
• Confirm the blister is explicitly noted as non-thermal to differentiate from burn blisters.
