Low back pain ICD-10 code
The ICD-10-CM code for low back pain is M54.50 — low back pain, unspecified. It is billable and valid for submission on a claim. There are 14 related codes, and which one you use depends on what the documentation supports.
Also written as lbp, lumbago, back pain.
The mistake coders make here
M54.5 alone is no longer valid — it was subdivided. M54.50 unspecified, M54.51 vertebrogenic, M54.59 other. Claims still submitted with plain M54.5 reject.
