What This Code Means

Death of bone tissue in one or more fingers caused by a previous injury when the specific side (left or right) is not documented or specified.

Coding Tips

•Use only when finger involvement is confirmed but laterality is unspecified
•Query provider to determine which hand is affected for more precise coding

Clinical Significance

Unspecified finger osteonecrosis following trauma represents localized bone death that can severely impact hand function and quality of life. This condition often requires multidisciplinary management including orthopedic surgery, hand therapy, and pain management to achieve optimal outcomes.

Documentation Requirements

✓Documentation of finger involvement without specified laterality
✓Clear history of previous trauma to finger(s)
✓Evidence of bone necrosis in phalangeal structures
✓Justification for unspecified laterality (bilateral involvement or unclear documentation)
✓Current functional assessment and range of motion
✓Pain levels and grip strength evaluation
✓Treatment modalities attempted and response
✓Impact on daily activities and occupational function
