Map (third character K) is a very narrowly defined ICD-10-PCS root operation. By definition, Map procedures are used to locate the route of passage of electrical impulses and/or locate functional areas in a body part.
Map only applies to the cardiac conduction mechanism and the central nervous system, so we only have two possible body systems for Map:
- Central nervous system (00K)
- Heart and great vessels (02K)
If you look at those tables, you’ll see very few options. The table for the central nervous system offers these body parts:
- 0, brain
- 7, cerebral hemisphere
- 8, basal ganglia
- 9, thalamus
- A, hypothalamus
- B, pons
- C, cerebellum
- D, medulla oblongata
For the heart and great vessels, we get only one body part choice: conduction mechanism.
Examples of Map procedures include:
- 00K83ZZ, percutaneous mapping of basal ganglia
- 00K00ZZ, intraoperative whole brain mapping via craniotomy
- 00K74ZZ, mapping of left cerebral hemisphere, percutaneous endoscopic
- 02K80ZZ, intraoperative cardiac mapping during open heart surgery
