About ICD-9-CM 31.94

31.94 is an ICD-9-CM procedure code for injection of locally-acting therapeutic substance into trachea. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-PCS took over.

The CMS General Equivalence Mappings translate it to 3 ICD-10-PCS codes, such as 3E0F3GC (Introduction of Other Therapeutic Substance into Respiratory Tract, Percutaneous Approach), 3E0F7GC (Introduction of Other Therapeutic Substance into Respiratory Tract, Via Natural or Artificial Opening) and 3E0F8GC (Introduction of Other Therapeutic Substance into Respiratory Tract, Via Natural or Artificial Opening Endoscopic). All of these are approximate matches, so review the record to pick the right one.
