About ICD-9-CM 01.10

01.10 is an ICD-9-CM procedure code for intracranial pressure monitoring. 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 6 ICD-10-PCS codes, such as 4A003BD (Measurement of Intracranial Pressure, Percutaneous Approach), 4A007BD (Measurement of Intracranial Pressure, Via Natural or Artificial Opening) and 4A008BD (Measurement of Intracranial Pressure, Via Natural or Artificial Opening Endoscopic). All of these are approximate matches, so review the record to pick the right one.
