Go online for your updated abdominal pain diagram In Pediatric Coding Alert, vol. 12, no. 6, the diagram of the abdomen reversed the bottom two quadrants and their identifying ICD-9 codes. Thanks to an astute reader for catching that the ICD-9 code for the RLQ- Right Lower Quadrant is incorrectly listed as 789.04 and the LLQ- Left Lower Quadrant is incorrectly listed as 789.03. The arrows should have instead indicated the RLQ- Right Lower Quadrant as 789.03 and the LLQ- Left Lower Quadrant as 789.04.
