AHA Coding Clinic® for ICD-9 - 2006 Issue 4; VOLUMES 1 AND 2 NEW/REVISED CODES
Major Osseous Defect
Effective October 1, 2006, code 731.3, Major osseous defect, was created for osseous defects. Osseous defects are the result of extensive bone loss, commonly in the area of the hip joint. Causes of this bone loss include peri-prosthetic osteolysis from a joint replacement, osteomyelitis, aseptic or osteonecrosis, benign or malignant neoplasm, pathologic fracture, severe osteoporosis, trauma, or a combination of these conditions. For example, a defect or cavity may be created when osteolysis causes a joint prosthesis to become loose on bone that is weakened by osteoporosis. While some bone loss is common when a joint has been...

Article Overview
This premium article covers the addition of a diagnosis code for major osseous defects, the clinical situations associated with extensive bone loss, and the surrounding coding context for orthopedic repair and grafting cases. It is aimed at coding professionals who need to understand when this diagnosis applies and how it relates to underlying disease categories and procedure coding in joint reconstruction scenarios.
Why This Topic Matters
Major bone loss can affect both diagnosis reporting and procedure coding in orthopedic claims. Understanding the relevant classification update and the associated orthopedic context helps coders review complex joint repair cases more accurately.
Article Sections
-
Classification update and clinical context
Introduces the diagnosis classification change and describes the general orthopedic settings in which major bone loss may be encountered. It also outlines the broader types of underlying conditions associated with these cases.
-
Treatment considerations for hip and knee defects
Summarizes the general treatment approaches discussed for major osseous defects in major joint reconstruction. The section focuses on the broad use of grafting and structural support in orthopedic repair.
-
Related diagnosis categories
Lists the surrounding diagnosis classification context and indicates that underlying disease should be coded when known. This section places the topic within the broader set of related bone and joint conditions.
-
Coding question and example case
Presents a sample orthopedic revision scenario and asks how the case should be coded. The example is used to illustrate the relationship between diagnosis reporting and procedure selection in a complex joint case.
