Sternal manubrial dissociation, subs for fx w routn heal

This code describes a condition where the manubrium, the upper part of the sternum, has separated from the body of the sternum. This specific code indicates that the patient is in the healing phase of the fracture, and the healing process is progressing routinely without complications.

Use this code for follow-up encounters with a patient who has previously been diagnosed with a sternal manubrial dissociation. This applies when the fracture is undergoing normal healing and the patient is receiving routine care, such as cast changes, physical therapy, or medication management during the recovery period.

• Ensure the encounter is for follow-up care and not the initial treatment of the fracture.
• Verify documentation explicitly states "routine healing" or similar to differentiate from delayed or nonunion healing.
• Always sequence this code after any applicable external cause codes, if relevant to the encounter.
