About coding chest pain
The ICD-10-CM code for chest pain is R07.9 (Chest pain, unspecified). The official index lists 6 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R07.9.
Within R07, choose R07.9 (Chest pain, unspecified) only when documentation doesn't support a more specific option: pain in throat (R07.0), chest pain on breathing (R07.1), Precordial pain (R07.2) and other chest pain (R07.8).
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.
