Burn unsp degree of single l finger except thumb, subs

This code indicates a burn of an unknown severity affecting a single finger on the left hand, excluding the thumb, where the burn's depth has not been specified. It specifically applies to the nail area or the entire finger. This diagnosis is used when the patient is receiving follow-up care for the burn.

Use this code for subsequent encounters when a patient presents for ongoing treatment, dressing changes, or evaluation of a burn to a single left finger (not the thumb) where the degree of the burn was not documented or is unknown. This applies to situations where the initial injury has already been assessed and coded.

• Ensure the documentation clearly specifies a left finger (excluding the thumb) and that the encounter is for follow-up care.
• Only use this code when the burn degree is truly unspecified; if a degree is documented, a more specific code should be chosen.
• Verify that the burn is to a single finger; if multiple fingers are involved, a different code may be appropriate.
