Introduction: Primary care physicians play a key role in managing patient access to healthcare. The COVID-19 pandemic has changed the organization of access to healthcare, giving primary care professionals (doctors, nurses, physiotherapists) additional tools for communicating with patients, in particular the possibility of communicating remotely (teleconsultations) through both verbal and video communication. Objective: The role and tasks of primary care physicians in the face of the emergence of a new disease entity. Material and methods: For patients who had codes after 2019 (and practically from 2020), additional data was collected on gender, age from 2018 to 2024, divided into subsequent years. The analyzed data set covered 68,926 people who were provided with healthcare services in all primary care healthcare facilities of the Ministry of Interior and Administration. Results: The number of patients in individual organizational units who had diagnoses from the scope after 2019/2020 is presented in the table below. The number of patient's visits has been steadily decreasing, with an average rate of decline of "-2.66%". Discussion: Disease definitions and the assignment of a diagnostic code are often asynchronous and iterative. Despite the relatively early recognition of this condition, ICD-10 connected with COVID codes were not used in clinical settings until October 2021, and currently this group of codes may also prove insufficient (taking into account the phenotypic variability and severity of the disease) for marking post-COVID cases. Conclusions: Considering the possibility of various complications generated by a given disease entity, it is extremely important to assign it to a given code, not only for statistical reasons.
