About coding torticollis
The ICD-10-CM code for torticollis is M43.6 (Torticollis). The official index lists 10 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on M43.6.
Within M43 (other deforming dorsopathies), M43.6 is specifically for torticollis. Related codes cover Spondylolysis (M43.0), spondylolisthesis (M43.1), fusion of spine (M43.2), recurrent atlantoaxial dislocation with myelopathy (M43.3), other recurrent atlantoaxial dislocation (M43.4), other recurrent vertebral dislocation (M43.5), other specified deforming dorsopathies (M43.8) and deforming dorsopathy, unspecified (M43.9).
Don't report M43.6 together with the conditions in its Excludes1 note: congenital (sternomastoid) torticollis (Q68.0), current injury - see Injury, of spine, by body region, ocular torticollis (R29.891), psychogenic torticollis (F45.8) and 2 more.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
