Other superficial injuries of left thumb, subs encntr

This code signifies a superficial injury to the left thumb, such as a bruise, abrasion, or minor cut, that is being treated during a follow-up visit. It indicates that the initial treatment for the injury has already occurred, and the patient is now presenting for subsequent care, monitoring, or rehabilitation.

Use this code for follow-up encounters related to minor, non-open wounds of the left thumb, like contusions or scrapes, after the initial diagnosis and treatment. This includes visits for wound checks, dressing changes, or assessment of healing progress for injuries that did not involve a significant break in the skin or underlying tissue damage.

• Ensure the documentation clearly specifies "left thumb" and a "superficial" injury type.
• Confirm the encounter is for subsequent care, not the initial treatment, as indicated by the "D" seventh character.
• Do not use for open wounds, fractures, sprains, or more severe injuries; these require different codes.
