About coding Fourchette laceration
The ICD-10-CM code for Fourchette laceration is O70.0 (First degree perineal laceration during delivery). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on O70.0.
Within O70 (perineal laceration during delivery), O70.0 is specifically for first degree perineal laceration during delivery. Related codes cover second degree perineal laceration during delivery (O70.1), third degree perineal laceration during delivery (O70.2), fourth degree perineal laceration during delivery (O70.3), anal sphincter tear complicating delivery, not associated with third degree laceration (O70.4) and unspecified (O70.9).
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 769 (Postpartum and Post Abortion Diagnoses with O.R. Procedures, relative weight 1.6673) and DRG 776 (Postpartum and Post Abortion Diagnoses without O.R. Procedures, relative weight 0.6721), in MDC 14 (Pregnancy, Childbirth and the Puerperium), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
