About coding chest discomfort
The ICD-10-CM code for chest discomfort is R07.89 (Other chest pain).
Within R07.8, choose R07.89 (Other chest pain) only when documentation doesn't support a more specific option: pleurodynia (R07.81) and intercostal pain (R07.82).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 313 (Chest Pain, relative weight 0.7114), in MDC 05 (Diseases and Disorders of the Circulatory System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
