Disp fx of neck of fourth MC bone, right hand, sequela

This code signifies a past fracture of the neck of the fourth metacarpal bone in the right hand that was displaced and is now causing a long-term complication or residual effect. This could include ongoing pain, stiffness, deformity, or functional limitation directly attributable to the previous injury. The "sequela" indicates that the acute phase of the fracture has passed, and the current encounter addresses a chronic issue stemming from it.

This code is appropriate for encounters where a patient presents with a chronic condition or complication directly resulting from a previously displaced fracture of the right fourth metacarpal neck. Examples include follow-up appointments for persistent malunion, nonunion, post-traumatic arthritis, or chronic pain after the initial healing period. It should be used when the focus of the encounter is on managing these long-term effects.

• Always ensure documentation clearly links the current condition to the past displaced fracture of the right fourth metacarpal neck.
• Do not use this code for the initial treatment of an acute fracture or for routine follow-up of a healing fracture without documented sequelae.
• Consider additional codes for specific sequelae, such as M20.0x for malunion or M19.041 for post-traumatic arthritis, if applicable and documented.
