Death of bone tissue in the right wrist bones (carpus) caused by medication side effects.
Coding Tips
- •The carpus refers to the small wrist bones; ensure this is the correct anatomical location documented
- •Identify the specific medication responsible for the osteonecrosis in the clinical documentation
Clinical Significance
Drug-induced osteonecrosis of the right carpus affects the complex wrist bone structure, potentially compromising hand function and grip strength. This condition can significantly impact activities of daily living and requires specialized orthopedic management for optimal outcomes.
Documentation Requirements
- ✓Specific documentation of right carpal bone involvement
- ✓Identification of causative medication with exposure details
- ✓Advanced imaging confirming carpal osteonecrosis (MRI preferred)
- ✓Clinical assessment of wrist pain and functional limitations
- ✓Evaluation of grip strength and range of motion deficits
- ✓Drug therapy timeline and relationship to symptom development
- ✓Treatment plan including splinting, therapy, or surgical options
- ✓Provider statement linking drug use to osteonecrosis development
