About coding postural adolescent kyphosis
The ICD-10-CM code for postural adolescent kyphosis is M40.00 (Postural kyphosis, site unspecified). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on M40.00.
Within M40.0, choose M40.00 (site unspecified) only when documentation doesn't support a more specific option: cervicothoracic region (M40.03), thoracic region (M40.04) and thoracolumbar region (M40.05).
Code first: underlying disease.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
