What This Code Means

Death of bone tissue in one or more fingers on the left hand caused by a previous injury, potentially affecting grip and fine motor function.

Coding Tips

•Verify left-side finger involvement is documented before assigning this code
•Distinguish from right finger codes (M87.244) and hand codes (M87.242)

This condition requires specialized hand surgery consultation and comprehensive rehabilitation to optimize functional outcomes and prevent further complications.

✓Clear identification of left finger(s) involvement
✓Documentation of previous trauma to left finger(s)
✓Clinical or radiological evidence of bone death in phalangeal bones
✓Specification of which fingers are affected when possible
✓Assessment of dominant hand impact
✓Current functional limitations and pain assessment
✓Treatment history and effectiveness
✓Impact on work and activities of daily living
