Penelitian ini dilatarbelakangi oleh masih tingginya pengembalian berkas klaim Inacbg’s Rawat Inap di RS Kanker “Dharmais” dimana pengembalian tertinggi disebabkan oleh konfirmasi koding dan resume medis. Hal ini berpotensi menimbulkan kerugan bagi RS akibat pembayaran klaim yang tertunda. Penelitian ini bertujuan untuk melakukan analisis kelengkapan dan ketepatan komponen diagnosis, prosedur dan koding terhadap besaran tarif klaim INA-CBG’s rawat inap di RS Kanker “Dharmais”. Studi kasus ini menggunakan pendekatan kualitatif dengan wawancara mendalam dan telaah resume medis pasien kanker payudara yang mendapatkan kemoterapi selama bulan Maret 2018. Hasil penelitian menunjukkan bahwa ketidaklengkapan pengisian resume medis tertinggi dalam pengisian indikasi masuk rawat 41%, pemeriksaan fisik 20%, dan pemeriksaan penunjang 4% dari total 45 kasus yang ditelaah. Angka ketidaksesuaian penulisan diagnosis sekunder dan prosedur berturut-turut sebesar 40% dan 37.8%. Namun penulisan diagnosis utama sudah sesuai antara rekam medis dan resume medis. Ketidaktepatan koding diagnosis utama masih ditemukan yaitu sebesar 17.8%. Akibat dari ketidaktepatan koding diagnosis utama, ketidaksesuaian diagnosis sekunder dan ketidaksesuaian prosedur/tindakan terdapat selisih negatif sebesar Rp. 142.763.800. Untuk itu komitmen dari manajemen RS Kanker “Dharmais” yaitu tim yang terlibat dalam koding final yang merupakan tim internal rumah sakit perlu diperkuat dalam rangka meningkatkan kualitas berkas klaim dari aspek kelengkapan dan ketepatan diagnosis, prosedur dan koding sehingga didapatkan nilai klaim INA-CBG’s yang tepat.
