S20.121D
ICD-10-CMBlister (nonthermal) of breast, right breast, subsequent encounter
This diagnosis code indicates a non-heat-related fluid-filled lesion on the right breast. This blister is not due to burns or frostbite, but rather from other causes such as friction, pressure, or an allergic reaction. The "D" suffix signifies that this is a subsequent encounter for the management of this specific injury.
Apply this code when a patient presents for follow-up care, such as wound checks, dressing changes, or medication adjustments, for a non-thermal blister previously diagnosed on their right breast. This includes situations where the blister is healing, has ruptured, or is being monitored for complications.
