Inferior subluxation of unspecified humerus, init encntr

This code signifies a partial dislocation of the shoulder joint where the head of the humerus has slipped downwards out of the glenoid fossa, but still maintains some contact. It specifically refers to an injury where the affected side (left or right) is not documented.

This code is appropriate for the initial treatment of an inferior subluxation of the humerus when the laterality is unknown or unspecified in the medical record. This might occur following trauma, such as a fall or direct impact to the shoulder.

• Always strive for laterality (left or right) documentation from the provider.
• If laterality is specified, use the appropriate S43.031- or S43.032- code.
• The "A" seventh character indicates an initial encounter for active treatment of the injury.
