About R07.2

R07.2 is the ICD-10-CM diagnosis code for Precordial pain. It belongs to category R07 (pain in throat and chest), block R00-R09 (symptoms and signs involving the circulatory and respiratory systems) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within R07 (pain in throat and chest), R07.2 is specifically for Precordial pain. Related codes cover pain in throat (R07.0), chest pain on breathing (R07.1), other chest pain (R07.8) and chest pain, unspecified (R07.9).

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 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.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 786.51 (Precordial pain).
