Checking J codes if supported basing on Medical Records submitted

Best answers
Can Anyone help me as to how the number units are computed basing on the billed unit that the provider submits ? Example

Code J1100 is Injection, dexamethasone sodium phosphate, 1 mg

Based on the medical records , Provider is billing 8 units of the J1100 . Medical record states "The injection consisted of 8cc, w/o epinephrine of 1% lidocaine, 4 mg of dexamethasone and into multiple trigger points.

Will it be supported ? or denied ?
