Nondisp fx of prox phalanx of fngr, subs for fx w delay heal

This code signifies a fracture of the proximal phalanx in any finger other than the thumb, where the bone fragments remain in their normal anatomical alignment. The patient is in the healing phase following initial treatment, but the fracture is not mending at the expected rate.

Use this code for follow-up encounters when a patient with a previously diagnosed and treated nondisplaced proximal phalanx fracture of a finger (excluding the thumb) presents with evidence of delayed healing. This includes situations where imaging shows persistent fracture lines or clinical signs indicate a prolonged recovery period.

• Ensure documentation explicitly states "nondisplaced" and identifies the specific finger (other than the thumb).
• Confirm the encounter is for follow-up care related to the fracture's healing, not initial treatment or a new injury.
• Pair with an external cause code if the mechanism of injury is relevant and documented.
