What ACHI codes should be assigned for decompression of colonic pseudo-obstruction and gastric pseudo-obstruction?
Refer to the clinical documentation to obtain information as to how the decompression was performed e.g. was it via an endoscope or insertion of tube, or was it done at time of an open procedure?
This will then determine if the decompression is coded or not, see ACS 0042 Procedures normally not coded, point 13 Nasogastric intubation, aspiration and feeding.
For this query NZCA reviewed the operation reports for two cases. In both cases a flexible sigmoidoscopy was performed to decompress the colon.
Therefore, assign the procedure code 32084-00  Fibreoptic colonoscopy to hepatic flexure for the flexible sigmoidoscopy only and use free text to specify the decompression e.g. Flexible sigmoidoscopy with decompression of pseudo-obstruction.
