ICD-10 code for birth injury paralysis

The ICD-10-CM code for birth injury paralysis is P14.9 (Birth injury to peripheral nervous system, unspecified). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on P14.9.

Within P14, choose P14.9 (unspecified) only when documentation doesn't support a more specific option: Erb's paralysis due to birth injury (P14.0), Klumpke's paralysis due to birth injury (P14.1), phrenic nerve paralysis due to birth injury (P14.2), other brachial plexus birth injuries (P14.3) and birth injuries to other parts of peripheral nervous system (P14.8).

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 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), 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.
