A35 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM A35 became effective on October 1, 2021. This is the American ICD-10-CM version of A35 - other international versions of ICD-10 A35 may differ.
Tdap vaccination offers the best prevention against pertussis, tetanus, and diphtheria. Tdap stands for tetanus and diphtheria toxoids with acellular pertussis. It is marketed under the brand names Adacel and Boostrix. Tdap is an inactive vaccine, which means it is made using dead bacteria.
DTaP is a vaccine that helps children younger than age 7 develop immunity to three deadly diseases caused by bacteria: diphtheria, tetanus, and whooping cough (pertussis). Tdap is a booster immunization given at age 11 that offers continued protection from those diseases for adolescents and adults.
Diphtheria, tetanus, and acellular pertussis booster vaccine (also known as Tdap) is a combination immunizing agent used to protect against infections caused by diphtheria, tetanus (lockjaw), and pertussis (whooping cough).
ICD-10 requires only one code (Z23) per vaccination, regardless if single or combination. Report Z23 for all vaccination diagnoses.
ICD-10-CM Description Clinicians may assign code Z28. 311, “Partially vaccinated for COVID-19,” when the patient has received at least one dose of a multi-dose COVID-19 vaccine regimen, but has not received the doses necessary to meet the CDC definition of “fully vaccinated” at the time of the encounter.
The Z23 code includes the following note: “Code first any routine childhood examination.” Therefore, when you provide immunizations in conjunction with a well-child visit, a code for routine child health examination should be reported first, followed by Z23 for any immunizations. This is similar to ICD-9 rules.
