This code signifies a chemical burn of indeterminate severity affecting multiple areas of the right shoulder and upper arm, excluding the wrist and hand. It indicates damage to the skin and underlying tissues caused by corrosive substances, without specifying the exact depth of the burn.

Use this code when documenting the initial treatment of a patient presenting with a chemical burn to various sites on their right shoulder and/or upper arm. This applies when the degree of the burn (e.g., first, second, third) is not yet determined or documented.

• Ensure documentation clearly specifies "unspecified degree" and multiple sites on the right shoulder and upper limb, excluding the wrist and hand.
• This "A" initial encounter character is only used for the first time the patient is seen for this specific injury.
• Do not use if the degree of the chemical burn is known; instead, select a more specific code from the T22.0-T22.3 series.
