About coding lumbar puncture complication

The ICD-10-CM code for lumbar puncture complication is G97.1 (Other reaction to spinal and lumbar puncture). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on G97.1.

Within G97, choose G97.1 (Other reaction to spinal and lumbar puncture) only when documentation doesn't support a more specific option: cerebrospinal fluid leak from spinal puncture (G97.0), intracranial hypotension following ventricular shunting (G97.2), intraoperative hemorrhage and hematoma of a nervous system organ or structure complicating a procedure (G97.3), accidental puncture and laceration of a nervous system organ or structure during a procedure (G97.4), postprocedural hemorrhage of a nervous system organ or structure following a procedure (G97.5), postprocedural hematoma and seroma of a nervous system organ or structure following a procedure (G97.6) and other intraoperative and postprocedural complications and disorders of nervous system (G97.8).

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 102 (Headaches with MCC, relative weight 1.1201), DRG 103 (Headaches without MCC, relative weight 0.822), DRG 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), in MDC 01 (Diseases and Disorders of the Nervous System) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
