Z30.46Encounter for surveillance of implantable subdermal contraceptive

Z30.46 is the ICD-10-CM diagnosis code for encounter for surveillance of implantable subdermal contraceptive. It belongs to category Z30 (encounter for contraceptive management), block Z30-Z39 (persons encountering health services in circumstances related to reproduction) and chapter 21 (factors influencing health status and contact with health services). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within Z30.4 (encounter for surveillance of contraceptives), Z30.46 is specifically for encounter for surveillance of implantable subdermal contraceptive. Related codes cover unspecified (Z30.40), contraceptive pills (Z30.41), injectable contraceptive (Z30.42), intrauterine contraceptive device (Z30.43), vaginal ring hormonal contraceptive device (Z30.44), transdermal patch hormonal contraceptive device (Z30.45) and other contraceptives (Z30.49).

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 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), 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 not acceptable as the principal diagnosis for an inpatient stay; it may be reported as a secondary diagnosis.

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

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

It was added in FY2017, effective October 1, 2016.

Before ICD-10, this condition was coded in ICD-9-CM as V25.43 (surveillance of implantable subdermal contraceptive).
