About coding Cervicobrachial diffuse syndrome
The ICD-10-CM code for Cervicobrachial diffuse syndrome is M53.1 (Cervicobrachial syndrome).
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.
