Nondisp fx of med malleolus of unsp tibia, 7thK

This code describes a fracture of the inner ankle bone (medial malleolus) of an unknown tibia that is not out of alignment. It indicates that the patient is receiving follow-up care for this fracture, which has not healed as expected despite the skin remaining intact. The "nonunion" aspect signifies a failure of the bone to mend completely.

Use this code for subsequent encounters when a patient presents with a previously diagnosed, nondisplaced, closed medial malleolus fracture of an unspecified tibia that has failed to unite. This would apply during follow-up appointments where the physician is monitoring the nonunion, considering further treatment, or managing complications related to the lack of healing.

• Ensure documentation clearly states "nonunion" and "nondisplaced" for the medial malleolus fracture.
• Verify that the encounter is "subsequent" and the fracture is "closed" to align with the code's specificity.
• If the laterality (left or right tibia) is known, a more specific code should be selected.
