Nondisp fx of base of fourth MC bone, left hand, sequela

This code describes a healed or residual condition resulting from a fracture at the base of the fourth metacarpal bone in the left hand, which was initially nondisplaced. It indicates that the acute phase of the fracture has passed, and the patient is now experiencing a long-term effect or complication related to the previous injury.

Use this code when documenting a patient presenting with a chronic issue, pain, stiffness, or functional limitation directly attributable to a previously sustained nondisplaced fracture of the base of the left fourth metacarpal. This is appropriate for follow-up encounters occurring after the initial healing period, where the fracture itself is no longer acute but its sequelae are being addressed.

• Always assign a sequela code (ending in 'S') for conditions that are residual effects of a past injury.
• Do not use this code for the initial treatment of an acute fracture; use an acute fracture code instead.
• Consider additional codes for specific sequelae, such as chronic pain (G89.29) or malunion (M84.0x), if documented.
