In simple words: This code describes a follow-up visit for frostbite that caused tissue damage to the right ear.

Frostbite with tissue necrosis of right ear, subsequent encounter. This code indicates that the patient has experienced frostbite resulting in tissue death (necrosis) specifically affecting their right ear. The "subsequent encounter" designation signifies that this is not the initial visit for this condition, implying ongoing care or follow-up for the frostbite injury.

Example 1: A patient presents for a follow-up appointment after being diagnosed with frostbite of the right ear two weeks prior. The initial injury resulted in tissue necrosis. The physician assesses the healing progress and adjusts the treatment plan., A patient with a history of frostbite to the right ear is seen for wound care and pain management related to the necrotic tissue., A patient who experienced frostbite to the right ear, leading to tissue necrosis, now presents with a secondary infection. The physician treats the infection while continuing to manage the frostbite injury.

Documentation should include the initial date of the frostbite injury, the location and extent of tissue necrosis, details of ongoing treatment, and evidence of the patient's subsequent encounters for this condition.
