About 08JMXZZ

08JMXZZ is the ICD-10-PCS code for a inspection procedure on the left extraocular muscle using an external approach. In ICD-10-PCS, inspection means visually and/or manually exploring a body part.

In plain terms, this corresponds to other nonoperative measurements and examinations, the ICD-9-CM procedure title it maps to (89.39).

For a different body part, codes include 08J0XZZ (right eye), 08J1XZZ (left eye), 08JJXZZ (right lens), 08JKXZZ (left lens) and 08JLXZZ (right extraocular muscle).

The same procedure with a different approach is coded 08JM0ZZ (open).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
