Corros first degree of unsp mult fngr, not inc thumb, subs

This code describes a superficial chemical burn (corrosion) affecting one or more fingers, excluding the thumb, where only the outermost layer of skin is damaged. The injury is mild, characterized by redness and pain, without blistering or deeper tissue involvement. This specific code is used for follow-up care after the initial treatment.

Apply this code for subsequent encounters when a patient presents for follow-up care of a first-degree chemical burn to multiple fingers (excluding the thumb). This includes situations like wound checks, dressing changes, or reassessment of healing after the initial injury has been addressed.

• Ensure the documentation clearly specifies a chemical burn (corrosion) and not a thermal burn.
• Verify that the burn is explicitly stated as first-degree and involves multiple fingers, excluding the thumb.
• Confirm this is a subsequent encounter, indicated by the "D" seventh character, meaning the patient is receiving routine care during the healing phase.
