Elevated sedimentation rate

This code indicates an abnormally high erythrocyte sedimentation rate (ESR), a non-specific inflammatory marker. An elevated ESR suggests the presence of inflammation, infection, or tissue damage within the body.

Use this code when laboratory results document an elevated sedimentation rate without a definitive diagnosis for the underlying cause. This is often seen in initial workups for systemic inflammatory conditions, infections, or certain autoimmune diseases before a specific etiology is identified.

• Do not code an elevated ESR when a definitive diagnosis explaining the elevation has been established (e.g., rheumatoid arthritis, osteomyelitis).
• This code is typically used as a secondary diagnosis, indicating an abnormal lab finding that requires further investigation.
• Ensure documentation clearly states "elevated sedimentation rate" or "high ESR" from lab reports.
