Anesthesia time begins when the anesthesiologist begin to prepare the patient for anesthesia. Anesthesia time ends when the anesthesiologist is no longer in personal attendance. Anesthesia time is calculated in intervals of 15 minutes
Coding Pain Management
Transforaminal epidural injection: 64479-64484
Transforaminal epidural injection is given at the nerve root in to the epidural space(64479-64484). The injection is passed through the foramen to reach the nerve root. These are unilateral codes and require 50 modifier for bilateral injections. The physician injects at the nerve root like L4 or between the vertebral interspaces like L4-L5.
Interlaminar injections: 62310-62311
Interlaminar injections are given in to epidural or subarahnoid space through lamina without passing through the foramen. The injection goes directly into the lamina unlike previous one which has to go through foramen and then lamina. These are nonneurolytic injections for diagnostic or therapeutic purposes including anesthetic, steroid, opoid or other substances. These injections also includes contrast if given.
Facet joint injections: 64422-64427
Code Range 64470-64472 is for injection of steroid and/or an anesthetic.
If any other type of substance is injected may be nondestructive or pulsed radiofrequency use 64999. Facet joint injection codes are unilateral and modifier 50 should be used for bilateral procedures. If a Neurolytic is injected for destruction, code range is 62280-62284.
Trigger point injection: 20550-20553
CPT codes 20552-20553 are reported only once per session. CPT code 20551 should be reported one time for multiple or single injections to a single tendon origin or tendon insertion performed. Injections to multiple tendon origins or tendon insertions are reported one time for each injection. For dry needling technique use unlisted procedure code 20999. Imaging guidance is reported separately like 77002 for fluoroscopic, 76942 for ultrasound, and 77021 for MR.

Coding spinal arthrodesis procedures
Before coding spinal arthrodesis procedures also called as spinal fusion, one must understand the actual procedures that the physician does. Lets have a look at the procedures involved in spinal fusion or arthrodesis.
The physician first performs spinal fusion either by anterior, posterior, or transverse method. One the fusion of vertebra is accomplished, the physician may perform insertion of intervertebral biomechanical devices like synthetic cages or methylmethacrylate. This will require the use of bone grafts for better fixation of the intervertebral devices. The physician may also take a bone marrow aspirate and and mix it with bone grafts before applying them. The bone grafts can be taken either from the same incision or through a separate incision else the physician may also prefer to use premanufactured bonegrafts called as allografts. Before placing the intervertebral cages the physican performs partial or medial laminectomy, diskectomy, and or foraminotomy to prepare the interspace. Once the cages are fixed, the physician performs spinal instrumentation.
CPT codes for arthrodesis and fusion: 22548-22812
CPT codes for application of spinal instrumentation: 22840-22855
CPT codes for spinal bone graft: 20930-20938
CPT codes for partial laminectomy with diskectomty posterior approach: 63020-63035
CPT codes for partial laminectomy with diskectomty anterior approach: 63075-63078
CPT codes for bone grafts, intervertebral cages, and spinal instrumentation are addon codes and are exempt from 51 modifier.
Autografts are grafts taken from the same patient.
Allografts are grafts taken from same species usually from cadavers.
Morselized bone grafts are small pieces or bone powder.
Structural bone graft is a single bone piece.
If the same type of graft is used more than only then only one code should represent it.

Upcoding
Upcoding refers to the practice of coding services which are not actually provided. This can be intentional or unintentional. Radiology coders should be aware that coding all that is documented in the conclusion of radiology reports can result in upcoding. For example, if a multibody CT Scan is done to access the extent of malignancy, the coders should not pick codes for cholelithiasis, kidney stones, calcifications if documented in the result of the CT Scan, as these are incidental findings and are not related to the purpose of imaging i.e. to access the malignancy. In the same way, if abdomen x-ray is done for abdominal pain, the radiologist may document degeneration of lumbar intervertebral disk which should not be coded.
