New in 2012

New Codes

Destruction by Neurolytic Agent (eg, chemical, thermal, electrical or radiofrequency)

64611: Chemodenervation of parotid and submandibular glands, bilateral. This code was created for reporting chemodenervation of the salivary glands. A parenthetical note has been added following the code, instructing users to report the code with modifier -52 if fewer than four salivary glands are injected.

New ICD-9 and CPT codes for 2012

For 2012, there are 4 newly introduced diagnosis codes you may want to be aware of:  

ICD-9 Code



Lambert-Eaton syndrome, unspecified


Lambert-Eaton syndrome in neoplastic disease

(Remember to code first the underlying neoplastic disease)


Lambert-Eaton syndrome in other diseases classified elsewhere

(Code first the underlying condition (e.g., Autoimmune disease, Vitiligo, etc.)


Other specified disorder of the bladder (i.e., bladder hypertrophy, contracted bladder)


Depending on the frequency of the reporting of these diagnoses at your facility, it may be beneficial to add these new codes to your billing forms.

For CPT 2012, EMG codes have been updated to add three new codes to be reported when performing studies the same day as nerve conduction tests. In addition, two new evoked potential codes were created for the reporting of testing on all 4 extremities at the same time.

CPT Code



Limited EMG, done with Nerve Conduction Studies


Complete EMG, done with Nerve Conduction Studies


Non-extremity EMG, done with Nerve Conduction Studies


SEP,  upper and lower extremities


MEP, upper and lower extremities


The new needle EMG codes are reported in addition to the nerve conduction codes 95900-95904 when nerve conduction studies are performed in conjunction with EMG on the same day. 

Codes 95885 and 95886 can be reported together up to a combined total of four units per patient when all four extremities are tested. 

For evoked potentials, new codes that combine both upper and lower limbs into a single code have been added to this series of codes.

Code 95938 combines both upper and lower limbs into a code when performing short-latency somatosensory evoked potential studies. 

Code 95939 combines both upper and lower limbs into a code when performing central motor evoked potential studies.

Each of these codes were created at the request of the CPT Panel to address concerns of duplicate work in the pre-procedure and post-procedure portion of testing when the services were being reported with more than one CPT code.
