Unspecified dislocation of left thumb, subsequent encounter

This code signifies a dislocation of the left thumb where the specific type of dislocation (e.g., open, closed, subluxation) is not documented. It indicates that the patient is receiving follow-up care for this injury, such as cast changes, physical therapy, or monitoring of healing.

Apply this code when documentation clearly states a left thumb dislocation, but lacks further specificity regarding the nature of the dislocation, and the patient is presenting for subsequent treatment after the initial encounter. This is appropriate for office visits, follow-up imaging, or rehabilitation sessions related to the initial injury.

• Ensure the documentation explicitly states "left thumb" and "dislocation" without further detail on the type.
• Verify that the encounter is not the initial treatment for the dislocation; the "D" seventh character indicates subsequent care.
• If the specific type of dislocation is documented (e.g., closed, open), a more specific code from the S63.1 series should be used.
