99392 is the CPT code for a well-child checkup for an established patient aged 1 through 4 years. 90460-51 and 90461 x 2 are used for the administration of the DTP vaccine, with 90460 for the first component of the vaccine and 90461 for each additional component (DTP is a combination vaccine, hence the need for multiple units of 90461). The -51 modifier indicates multiple procedures. 90700-51 is the CPT code for the DTP vaccine itself, with the -51 modifier again indicating it's part of multiple procedures. Z00.129 is the ICD-10-CM code for a well-child visit without abnormal findings, and Z23 is used for the encounter for immunization.
