Tricky one! Patient presented truly with sepsis due to a puncture wound in their back. The R65.10 is the principal diagnosis. The injury code indicates that it is a puncture wound of the lower back and pelvis but it does not penetrate into the retro peritoneum, the last character of the code indicates that it is an initial encounter. The A41.9 code is for sepsis, unspecified organism.Rate this question:
