About coding thoracic spine pain
The ICD-10-CM code for thoracic spine pain is M54.6 (Pain in thoracic spine). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on M54.6.
Within M54 (dorsalgia), M54.6 is specifically for pain in thoracic spine. Related codes cover panniculitis affecting regions of neck and back (M54.0), radiculopathy (M54.1), Cervicalgia (M54.2), sciatica (M54.3), Lumbago with sciatica (M54.4), low back pain (M54.5), other dorsalgia (M54.8) and unspecified (M54.9).
Don't report M54.6 together with the conditions in its Excludes1 note: pain in thoracic spine due to intervertebral disc disorder (M51.-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
