Sltr-haris Type IV physeal fx unsp metatarsal, sequela

This code describes a Salter-Harris Type IV fracture affecting the growth plate of an unidentifiable metatarsal bone in the foot, where the fracture has healed but is causing ongoing issues. A Type IV fracture involves both the epiphysis and metaphysis, extending through the physis. The "sequela" designation indicates that this code is used for complications or conditions arising as a direct result of the original injury, long after the initial healing phase.

This code is appropriate when documenting chronic pain, deformity, growth disturbance, or other long-term complications directly attributable to a previously sustained Salter-Harris Type IV fracture of an unspecified metatarsal. It should be used for follow-up encounters addressing these residual effects, not for the initial acute injury.

• Always use this code as a secondary diagnosis, following a primary code that describes the specific sequela (e.g., M21.00 for unspecified deformity).
• Ensure documentation clearly links the current condition to the prior Salter-Harris Type IV metatarsal fracture.
• Avoid using this code for acute or subacute fracture care; it is strictly for long-term effects.
