- Billable — Valid for Submission
- CC — Complication or Comorbidity
- Not Chronic
I97.51 is a billable ICD-10-CM diagnosis code for accidental puncture and laceration of a circulatory system organ or structure during a circulatory system procedure. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 791, 793, 919 through 921. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 78 closely related codes. Coders also document this condition as perforation of left ventricle due to procedure. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Postprocedural or postoperative circulatory system complication.

Questions About I97.51Overview
Is I97.51 a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report accidental puncture and laceration of a circulatory system organ or structure during a circulatory system procedure on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does I97.51 group to?
When accidental puncture and laceration of a circulatory system organ or structure during a circulatory system procedure is the principal diagnosis on an inpatient stay, it groups to MS-DRG 793, 791, 920, 919, 921, with relative weights from 0.6719 to 4.2192 depending on complications. Higher weights mean higher Medicare reimbursement.
Is I97.51 a CC or MCC?
CMS lists I97.51 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 78 closely related codes in its exclusion list.
What is the ICD-9 equivalent of I97.51?
Under the General Equivalence Mappings, accidental puncture and laceration of a circulatory system organ or structure during a circulatory system procedure converts to ICD-9-CM 998.2 (accidental op laceration). The mapping is approximate, so confirm the match fits the documentation.
