Blister (nonthermal) of right middle finger, init encntr

This code signifies a non-burn related blister located on the right middle finger. This type of blister typically results from friction, pressure, or other mechanical trauma, rather than exposure to heat or chemicals. It indicates the initial presentation and treatment of this specific injury.

Apply this code when documenting a patient presenting with a blister on their right middle finger that is not caused by a thermal source (e.g., heat, cold, chemical). This is appropriate for conditions like a friction blister from a tool or a tight glove, or a blister from a pinch injury. It should be used for the first time the patient is seen for this particular injury.

• Ensure the blister is explicitly documented as non-thermal and located on the right middle finger.
• Verify that this is the patient's initial encounter for this specific blister, not a follow-up visit.
• Consider additional codes for any underlying cause of the trauma if applicable and documented.
