Code Description

ICD-10 M87.133 is a billable code used to indicate a diagnosis of osteonecrosis due to drugs of unspecified radius.

Key Diagnostic Point:

Osteonecrosis, also known as avascular necrosis, is a condition characterized by the death of bone tissue due to a lack of blood supply. This specific code, M87.133, refers to osteonecrosis that is induced by the use of certain medications, although the specific radius affected is unspecified. Commonly implicated drugs include corticosteroids and bisphosphonates, which can disrupt blood flow to the bone. The condition often presents with pain and limited mobility in the affected area, which can lead to significant orthopedic complications, including fractures and joint degeneration. Diagnosis typically involves imaging studies such as X-rays or MRI, which can reveal changes in bone density and structure. Treatment options may include medication adjustments, physical therapy, or surgical interventions such as joint replacement, depending on the severity of the condition. Understanding the underlying causes and the specific medications involved is crucial for effective management and coding.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of osteonecrosis, improving the ability to track drug-induced cases and their outcomes. This specificity aids in better patient management and research into the effects of medications on bone health.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of osteonecrosis, improving the ability to track drug-induced cases and their outcomes. This specificity aids in better patient management and research into the effects of medications on bone health.

Reimbursement & Billing Impact
