Question: Encounter notes indicate that a patient suffers from right-sided lumbago and sciatica. What ICD-10 code(s) should I report? I was thinking M54.31 and M54.50. Connecticut Subscriber Answer: You shouldn’t report either of the codes you mentioned for this patient’s diagnosis. Instead, report M54.41(Lumbago with sciatica, right side).
The ICD-10 codes you chose — M54.31 (Sciatica, right side) and M54.50 (Low back pain, unspecified) — are technically accurate to report this patient’s condition. However, you should always choose a single diagnosis code when it can accurately portray what two (or more) codes can portray.
