If a patient has CKD stage 4 and comes in with AKI on CKD, how would you code this? The provider wants to code it as N17.9, N18.9 (for AKI on CKD) and N18.4. My thought since stage 4 is known, there is no need for N18.9 since N18.4 is coded to the highest specificity. Thank you for your suggestions.
