Chronic low back pain

low back pain = 724.2

other chronic pain = 338.29

Documentation states chronic low back pain.

Under icd9datacom - Disease Synonyms - Chronic low back pain is there. I do not see this description within the icd9 manual.

For chronic low back pain - would you use 724.2 or 338.29

I would think 338.29 would be the more correct code to use. Is this correct?

Thanks.
