ICD-9 to ICD-10 Conversion: Simplify Pain Dx: Get Confident on G89

Go for site specific codes and involve psychological factors.

You must be careful while reporting the codes that come from the G89 category. These particular codes are never allocated in case the definitive diagnosis is recognized. The lone exception is when the purpose for the encounter is mainly pain control and not the management of the original condition per se. See the examples listed below for neurosurgery applications you might face in the ICD-9 to ICD-10 conversion:

1) In case the neurosurgeon implants a neurostimulator for control of pain, you then report the pain code as the major or firstlisted diagnosis.

2) In case the patient comes to the neurosurgeon for management of pain post a displaced intervertebral disc, you report G89 code and the primary condition can be reported as an added diagnosis.

3) In case the patient reports to the neurosurgeon for spinal fusion, you, then, do not report the G89 category code. In its place, you report the chief diagnosis; like the spinal stenosis or a vertebral fracture.

G89 Should Be Combined with Site-Specific Pain Codes

When ICD-9 to ICD-10 transition takes place, you can use the G89 category code together with codes that explain the site of pain. You arrange the two codes according to the conditions.

Example: In case a patient withstands an acute neck injury in an accident and your neurosurgeon offers treatment for pain, you assign code G89.11 (Acute pain due to trauma) and you also report M54.2 (Cervicalgia) to explain the site of pain. Though, in case your neurosurgeon is treating the patient for a different reason, then you assign the G89 code only as a secondary diagnosis.

Note the One-To-One Match

ICD-10 includes a one-to-one match for numerous pain codes in ICD- 9. Below are the selections you will have once ICD-9 to ICD-10 transition goes into effect in October 2013.

Distinguish Postoperative vs. Postprocedure

In ICD-9, you have 338.18 (Other acute postoperative pain) which matches to G89.18 (Other acute postprocedural pain) in ICD-10. Likewise, 338.28 (Other chronic postoperative pain) matches up to G89.28 (Other chronic postprocedural pain) in ICD-10. There is a modification from ‘postoperative' to ‘postprocedure' in these pairs. G89.18 includes both postoperative pain NOS along with postprocedural pain NOS. The presence of postprocedure pain recognizes those conditions where a procedure for instance lumbar puncture or further percutaneous treatment leads to acute or chronic pain.

Involve Psychological Factors

Pain is essentially an emotional experience. There may be an additional psychological component which you are not supposed to miss. When ICD-9 to ICD-10 transition take place, the ICD-10 code for the psychological factors is F45.42 (Pain disorder with related psychological factors) which matches to 307.89 (Other, pain disorder related to psychological factors) in ICD-9. Ensure that you have backup documents for the psychological factors.
