About P14.1

P14.1 is the ICD-10-CM diagnosis code for Klumpke's paralysis due to birth injury. It belongs to category P14 (birth injury to peripheral nervous system), block P10-P15 (birth trauma) and chapter 16 (certain conditions originating in the perinatal period). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within P14 (birth injury to peripheral nervous system), P14.1 is specifically for Klumpke's paralysis due to birth injury. Related codes cover Erb's paralysis due to birth injury (P14.0), phrenic nerve paralysis due to birth injury (P14.2), other brachial plexus birth injuries (P14.3), birth injuries to other parts of peripheral nervous system (P14.8) and unspecified (P14.9).

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 794 (Neonate with Other Significant Problems, relative weight 1.4935), in 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.

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 767.6 (injury to brachial plexus due to birth trauma).
