G97.49Accidental puncture and laceration of other nervous system organ or structure during other procedure

G97.49 is the ICD-10-CM diagnosis code for accidental puncture and laceration of other nervous system organ or structure during other procedure. It belongs to category G97 (intraoperative and postprocedural complications and disorders of nervous system, not elsewhere classified), block G89-G99 (other disorders of the nervous system) and chapter 6 (diseases of the nervous system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within G97.4, choose G97.49 (and laceration of other nervous system organ or structure during other procedure) only when documentation doesn't support a more specific option: or laceration of dura during a procedure (G97.41) and and laceration of other nervous system organ or structure during a nervous system procedure (G97.48).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 791 (Prematurity with Major Problems, relative weight 4.1075), DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), DRG 919 (Complications of Treatment with MCC, relative weight 1.763), DRG 920 (Complications of Treatment with CC, relative weight 0.9975) and DRG 921 (Complications of Treatment without CC/MCC, relative weight 0.6722), in MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period) and MDC 21 (Injuries, Poisonings and Toxic Effects of Drugs), 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 998.2 (accidental puncture or laceration during a procedure, not elsewhere classified).
