ICD-10 code M54 for Dorsalgia is a medical classification as listed by WHO under the range -Other dorsopathies . ICD-10 code M54.9 for Dorsalgia, unspecified is a medical classification as listed by WHO under the range -Other dorsopathies .

A quick look in the Alphabetic Index of ICD-10-CM points you to M54.9 Dorsalgia, unspecified, which includes backache and back pain. Close enough, right? This could work, but let’s see if we can avoid an unspecified code.
