Blister (nonthermal) of lower back and pelvis, subs encntr

This code signifies a non-burn related blister located on the lower back or pelvic region. This type of blister is typically caused by friction, pressure, or other mechanical trauma, rather than heat or chemical exposure.

Apply this code when documenting follow-up care for a patient with a previously diagnosed nonthermal blister on the lower back or pelvis. This includes subsequent visits for wound care, monitoring healing progress, or addressing complications related to the initial injury.

• Ensure the documentation clearly states the blister is nonthermal and located specifically on the lower back or pelvis.
• Confirm this is a subsequent encounter for the condition, not the initial treatment.
• Look for associated documentation regarding the cause of the blister (e.g., friction from clothing, prolonged pressure).
