Osteomyelitis, unspecified

This code signifies an infection of the bone and bone marrow where the specific type, cause, or location of the osteomyelitis is not documented. It indicates a general diagnosis of bone infection without further detail.

Use this code when the medical record clearly states "osteomyelitis" but lacks information regarding its acuity (e.g., acute, chronic), causative organism, or specific anatomical site. This is a last resort when more specific codes cannot be assigned due to insufficient documentation.

• Avoid using this code if a more specific ICD-10-CM code for osteomyelitis can be identified (e.g., acute, chronic, specific bone, with or without pathogen).
• Query the provider for more specific details (e.g., site, acuity, organism) to allow for more precise coding.
• This code should be sequenced as the primary diagnosis when the osteomyelitis is the reason for the encounter.
