About coding maintenance contraception
The ICD-10-CM code for maintenance contraception is Z30.40 (Encounter for surveillance of contraceptives, unspecified). The official index lists 10 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Z30.40.
Within Z30.4, choose Z30.40 (unspecified) only when documentation doesn't support a more specific option: 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), implantable subdermal contraceptive (Z30.46) 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.
