ICD10 New Diagnosis Codes Z23

 

Z23 the ICD10 Vaccine Superhero

With ICD-10, new diagnosis codes will be implemented to change the way you bill. Codes like Z-23, this alpha/numeric superhero is helping with the confusion of diagnosis coding concerning vaccinations and routine health exams. Now you don’t have to remember, "Was it the V03 or was it V06.1?" The new code reduces time spent on complicated coding procedures and allows you to focus on your patient's needs. ICD-10 will recognize the type of vaccine you report with a CPT or HCPCS code gives sufficient detail about the type of immunization the patient needed.

The new coding information for the "Z" codes are found in Chapter 21 of the ICD-10 code book. Z00 – Z99 represent encounters besides disease or injury related visits. A00 – Y89 should always be reported as a primary reason for the encounter. The only exceptions to this can be when a person, who may or may not be sick, encounters the health services for some specific reason like receiving prophylactic vaccination (immunization), or to discuss a problem unrelated to an illness or injury. The other exception is when a problem is present which influences the person's health status but is not a current illness or injury.

Z23 is considered unacceptable as a principal diagnosis, always report A00 – Y89 as the primary reason for the encounter. When providing immunizations with a well-child visit, a code for routine child health examination should be reported first followed by Z23 for any immunizations. Guidelines for ICD-9 and V20.2 (routine infant / child health check) include immunizations appropriate to the patient's age. As a current example of the complexity of coding vaccines, under ICD-9, you have to report V04.81 for the influenza vaccine alone or V06.6 if you provide both the influenza vaccine and the pneumonia vaccine on the same date. ICD-9 codes V06.0-V06.9 are used for prophylactic vaccination and inoculation against combinations of diseases. Single vaccination V03-V05 codes are not included in the combination code. With Z23, reporting one code, regardless of how many or what types of vaccines are administered, will save valuable time.

Although the ICD-10 preventive codes are fairly straight-forward, they can still be complicated in part because of the Affordable Care Act. To receive insurance payments for preventive services covered under the ACA, you must properly code the combination of CPT and ICD-10 codes. Of course there could also be a villain in the Modifier -33. For information on modifier -33 and how it may affect payer reimbursement, stay tuned for more to come.
