About coding cervical root syndrome

The ICD-10-CM code for cervical root syndrome is M53.1 (Cervicobrachial syndrome). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on M53.1.

Within M53 (other and unspecified dorsopathies, not elsewhere classified), M53.1 is specifically for Cervicobrachial syndrome. Related codes cover Cervicocranial syndrome (M53.0), spinal instabilities (M53.2), sacrococcygeal disorders, not elsewhere classified (M53.3), other specified dorsopathies (M53.8) and dorsopathy, unspecified (M53.9).

The conditions in its Excludes2 note aren't part of M53.1, but may be coded alongside it if the patient has both: cervical disc disorder (M50.-) and thoracic outlet syndrome (G54.0).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
