Blister (nonthermal) of left middle finger, subs encntr

This code signifies a non-thermal blister located on the middle finger of the patient's left hand. This blister is not due to burns or frostbite, but rather from other causes such as friction, irritation, or an allergic reaction. The "D" in the code indicates that this is a subsequent encounter for the injury, meaning the patient is receiving follow-up care after the initial treatment.

Use this code when documenting follow-up care for a patient presenting with a blister on their left middle finger that is not burn-related. This includes scenarios where the patient is returning for wound checks, dressing changes, or evaluation of healing progress after the initial presentation and treatment of the blister.

• Ensure the blister etiology is clearly documented as non-thermal to avoid miscoding with burn codes.
• Verify laterality (left) and specific digit (middle finger) are accurately reflected in the medical record.
• Confirm that the encounter is indeed subsequent to the initial treatment of the blister, as indicated by the "D" seventh character.
