What This Code Means

A chronic bone infection of the hand bones that developed from bacteria spreading through the bloodstream, with unspecified laterality.

Coding Tips

• •Use this code only when documentation does not specify right or left hand
• •Query the provider if laterality can be determined from clinical notes or imaging reports

Clinical Significance

This code represents chronic hematogenous osteomyelitis of the hand when laterality is not specified in documentation. While still capturing the serious nature of chronic bone infection, the lack of laterality specification may indicate incomplete clinical documentation that should be improved for optimal patient care coordination.

Documentation Requirements

• ✓Evidence of chronic osteomyelitis (>6 weeks duration or recurrent)
• ✓Documentation of hematogenous origin (bloodstream spread)
• ✓Hand bone involvement without specified laterality
• ✓Imaging studies confirming bone infection
• ✓Laboratory evidence of active or chronic infection
• ✓Clinical symptoms consistent with chronic osteomyelitis
• ✓Treatment history and current management plan
• ✓Justification for unspecified laterality (bilateral involvement or unclear documentation)
