About coding Palpitations
The ICD-10-CM code for Palpitations is R00.2 (Palpitations). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on R00.2.
Within R00 (abnormalities of heart beat), R00.2 is specifically for Palpitations. Related codes cover tachycardia, unspecified (R00.0), bradycardia, unspecified (R00.1), other abnormalities of heart beat (R00.8) and unspecified abnormalities of heart beat (R00.9).
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 308 (Cardiac Arrhythmia and Conduction Disorders with MCC, relative weight 1.1806), DRG 309 (Cardiac Arrhythmia and Conduction Disorders with CC, relative weight 0.7316) and DRG 310 (Cardiac Arrhythmia and Conduction Disorders without CC/MCC, relative weight 0.568), 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.
