ICD-10 Quiz Time: Hypertension!
A patient has hypertension with chronic kidney disease (stage 3). Which code pair is correct?ICD-10 Quiz Time: Hypertension!
A patient has hypertension with chronic kidney disease (stage 3). Which code pair is correct?
A) I10 + N18.3-
B) I11.9 + N18.3-
C) I12.9 + N18.3-
D) I13.10 + N18.3-
Comment your answer below 👇
✅ Answer: C) I12.9 + N18.3-
📌 Why?
🔹 ICD-10-CM presumes a link between hypertension and CKD, unless the provider documents they are unrelated.
🔹 I12.- is hypertensive chronic kidney disease. Code the CKD stage after it with N18.-, for example N18.30, N18.31 (3a) or N18.32 (3b).
🔹 I10 is essential hypertension, used when there is no heart disease or CKD.
🔹 I11.- is hypertensive heart disease (no CKD).
🔹 I13.- is used when the patient has both heart disease and CKD.
💡 Coding tip: I12.- always needs an additional N18.- code for the CKD stage.

📌 Medical Billing Topic: Eligibility Issue
Insurance eligibility verification is a crucial step in the medical billing process! 🏥💻
An eligibility issue occurs when a patient's insurance coverage is inactive, expired, or the information provided does not match the insurance records.
🔹 Verify insurance eligibility before every visit.
🔹 Confirm the policy is active.
🔹 Check plan benefits and coverage limitations.
🔹 Update incorrect patient or insurance information.
🔹 Document discrepancies to help prevent claim denials and payment delays.
✅ Remember: Verify first, bill correctly, and reduce avoidable claim denials!

🧠 ICD-10 Quiz Time: Ulcerative Colitis!
Which code is used for ulcerative colitis, unspecified, without complications?
A) K50.90
B) K51.90
C) K52.9
D) K58.9
Comment your answer below 👇 and check the answer in this post's reply or after 24 hours.
✅ Answer: B) K51.90
📌 Why?
🔹 K50.- is Crohn's disease, so A is wrong.
🔹 K51.- is ulcerative colitis, and the 5th character 0 means without complications.
🔹 K52.9 is noninfective gastroenteritis and colitis, unspecified.
🔹 K58.9 is irritable bowel syndrome without diarrhea.
💡 Coding tip: if the documentation names the site (pancolitis, proctitis, left-sided colitis), use the specific K51.0-, K51.2- or K51.5- code instead of K51.9-.

❌ Services that need prior authorization
❌ Missed filing deadlines
❌ Duplicate claims
❌ Insurance eligibility not verified
