Wiki field block

From the Atlas of Primary Care Procedures, I found "field block", =
which appears to be a type of local anesthesia.

"Field block anesthesia describes the infiltration of local anesthetic =
in a circumferential pattern around a surgical site. Like nerve blocks, =
field blocks are used to anesthetize large areas of skin. Field blocks =
differ from nerve blocks in that more than one nerve experiences =
interruption of the nerve transmission. The technique permits large areas =
to be anesthetized, and it is useful for large dermatologic procedures. =
The field block does not disrupt the architecture of the surgical site and =
often is administered for facial or cosmetic repairs."

But they don't also provide the codinig which could represent a procedure with a similiar technique that has a CPT or just an unlisted code.
 
Field block is one type of regional block
depending upon the area where the peripheral Nerve block is given.- inrelation to the umbilicus would help us to select the code:-

Thoracoabdominal nerves T7-T11 - supplies(sensory) between internal oblique and transverse abdominal muscles and cutaneous supply:
T7-T9 superior to umbilicus
T10- at the level of umbilicus
T11-inferior to umbilicus
T12- (subcostal nerves)inferior to the umbilicus.
L1- illiohypogastric - to the wall inferior to the umbilicus.
L1- illioinguinal nerves- to the wall inferior to the umbelicus.

In so saying, we may have to select from the 64420- 64425 and would have to append with-59 for any of these nerve block.


I feel that filed block is a type of regional block , the regional block code 64421 would fit these scenerio.
However experts in pain management coding would clarify it better for us!
