Coding Tips

  • Document the type of body fluid exposure and the circumstances (needlestick injury, occupational exposure, healthcare worker exposure).
  • Use with codes for any resulting infections or post-exposure prophylaxis when applicable; this is critical for occupational health and infection control documentation.
