Procedure Overview
This family covers the surgical removal of an entire bone or bony structure in the leg, foot, pelvis, or related lower-body skeletal segment, without putting anything back in its place. It applies to structures such as the femur, tibia, fibula, patella, pelvic bones, tarsals, metatarsals, and toe phalanges. Surgeons turn to it when a bone segment is destroyed by infection, riddled with tumor, so badly fractured that repair isn't feasible, or deformed beyond what osteotomy or reshaping could correct.
Because resection takes out the whole named bony part rather than a fragment, it is a bigger step than excision or debridement. Patients encounter it most often in the context of bone cancer (primary or metastatic), chronic osteomyelitis that has not responded to antibiotics, or severe joint destruction where the diseased bone end must be cleared away before a prosthesis or graft can be placed. Depending on the site, the surgeon may reconstruct with a graft, implant, or amputation-level closure in a separate, later procedure.
Anatomy & Axis Detail
Metatarsal, Right
The right metatarsals are the five long bones connecting the tarsus to the toes, forming the forefoot's weight-bearing platform and the lever arm used in push-off during walking. Resection of an entire metatarsal is performed for malignant or aggressive benign bone tumors, severe chronic osteomyelitis, or extensive traumatic destruction, and because these bones anchor the forefoot's transverse and longitudinal arches, removing one alters load distribution across the remaining metatarsal heads and can predispose neighboring bones to transfer metatarsalgia. Coders should confirm the procedure removed the entire bone rather than a partial segment, and note the specific ray involved, since the first metatarsal's structural role differs from the lesser metatarsals.
Approach: Open
Open approach means the surgeon cuts through skin, mucous membrane, or other tissue layers to physically expose the target site to view before performing the procedure. It gives direct visualization and hands-on access, distinguishing it from Percutaneous approaches where instruments pass through a small puncture without exposing the site. Open is typical for procedures needing wide access, such as most laparotomies.
Coding & Documentation
The operative note has to state that an entire named bony part was removed, not a portion of it - documentation reading "partial resection" or "removed a segment of the shaft" points instead to Excision. Coders should confirm the specific bone or bone group from the ICD-10-PCS body part table (e.g., distal femur vs. entire femur can carry different values) and check whether the pathology report or op note supports a diagnosis - like tumor or osteomyelitis - that clinically justifies total removal.
A frequent error is defaulting to Resection whenever a large piece of bone is taken, when the correct read is Excision if any portion of the bone remains. Another is missing a same-operative-session Replacement or Supplement, which should be coded separately if a graft or device is placed after the bone is removed.
