What This Code Means

Death of bone tissue in the right hand (including metacarpal and phalangeal bones) due to causes other than trauma or infection, leading to bone deterioration and potential collapse.

Coding Tips

•This code covers osteonecrosis of hand bones beyond the carpus; specify which hand bones if documented
•Differentiate between carpal osteonecrosis (M87.837-839) and hand bone osteonecrosis (M87.84x)

Clinical Significance

Osteonecrosis of the right hand affects the metacarpal and phalangeal bones, potentially causing severe functional disability and chronic pain. This diagnosis has significant risk adjustment implications due to the complex care requirements, potential need for reconstructive surgery, and impact on activities of daily living.

Documentation Requirements

✓Specific identification of right hand bones (metacarpals, phalanges) affected by osteonecrosis
✓Documentation of osteonecrosis from causes other than idiopathic or drug-induced
✓Detailed imaging (MRI, X-ray, bone scan) confirming hand bone necrosis
✓Clinical presentation including right hand pain, swelling, and functional impairment
✓Exclusion of infectious or traumatic causes as primary etiology
✓Assessment of impact on grip strength, dexterity, and hand function
✓Documentation of any underlying conditions or contributing factors
✓Provider evaluation of treatment options and functional prognosis

Commonly Confused Codes

M87.041 — Idiopathic aseptic necrosis of right hand - specifically idiopathic etiology M87.043 — Idiopathic aseptic necrosis of unspecified hand - different cause and lacks laterality M86.841 — Other osteomyelitis, right hand - infectious bone disease rather than necrosis S62.301A — Unspecified fracture of fifth metacarpal bone, right hand - acute trauma rather than chronic necrosis M25.541 — Pain in joints of right hand - symptom rather than specific bone pathology
