Oth fx r patella, subs for opn fx type 3A/B/C w delay heal

This code signifies an open fracture of the right patella, specifically of types IIIA, IIIB, or IIIC, that is currently in a phase of delayed healing. It indicates that the initial injury has already occurred, and the patient is now receiving care for the ongoing healing process, which is progressing slower than expected.

Apply this code when documenting follow-up care for a patient with a previously diagnosed open fracture of the right patella (Gustilo-Anderson types IIIA, IIIB, or IIIC) who is experiencing delayed union or nonunion. This would be appropriate for subsequent encounters where the focus is on managing the delayed healing, such as wound care, monitoring for infection, or planning further interventions.

• Ensure documentation clearly specifies "delayed healing" for the right patella open fracture.
• Verify the Gustilo-Anderson classification (IIIA, IIIB, or IIIC) is explicitly stated or inferable from the clinical notes.
• This code is for subsequent encounters; an initial encounter code would have been used for the acute injury.
