About N98.3

N98.3 is the ICD-10-CM diagnosis code for complications of attempted introduction of embryo in embryo transfer. It belongs to category N98 (complications associated with artificial fertilization), block N80-N98 (noninflammatory disorders of female genital tract) and chapter 14 (diseases of the genitourinary 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 N98 (complications associated with artificial fertilization), N98.3 is specifically for complications of attempted introduction of embryo in embryo transfer. Related codes cover infection associated with artificial insemination (N98.0), Hyperstimulation of ovaries (N98.1), complications of attempted introduction of fertilized ovum following in vitro fertilization (N98.2), other complications associated with artificial fertilization (N98.8) and complication associated with artificial fertilization, unspecified (N98.9).

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 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 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 is on the CMS list of diagnoses consistent only with female patients (the sex-conflict edit itself was retired in FY2025).

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 997.99 (complications affecting other specified body systems, not elsewhere classified).
