Procedures: TTE
CT

Hospital Course:

This patient was transferred from an outside facility where he was initially treated for acute hypoxic respiratory failure 2/2 medications and subsequently developed AKI with a creatinine of 4.6 from his baseline of 2.4-2.8. At the time of admission he was on room air and creatinine was 2.7. Echo was repeated showing EF 25-30 (which is about baseline), cyclosporine 72 and mycophenolate 0.9.

Cardiology was consulted on admission and agreed advised to restart home doses of immune suppression once levels resulted. On 6/7 his creatinine began to rise to a high of 5.6 on 6/8 and WBC increased to a high of 31. Infectious disease recommended linezolid and cefepime which was stopped 6/10. He was changed to ceftriaxone then to cipro PO for a klebsiella UTI. He denied diarrhea; however c diff resulted positive, therefore he was started on flagyl, initially IV, then switched to PO after which his WBC improved. He was given a small amount of fluids and his creatinine returned to baseline of 2.8 at discharge. Rheumatology was consulted as he has tophaceous gout (due to renal impairment) with a uric acid of 11.4. They recommended increasing prednisone to 7.5mg daily with increasing to 20mg in case of flares and adding allopurinol 100mg daily. Prior to discharge he was restarted on carvedilol which he had not been taking for quite some time.

Physical Exam:

HEENT: Normocepahlic and atraumatic
Neck: Supple, no palpable lymphadenopathy
Pulmonary: Clear to auscultation bilaterally without any wheezing, rales, or ronchi
Cardiac: S1 S2, RRR, no rubs, murmurs, gallops
GI/Abdomen: obese, normal bowel sounds, soft, non-tender, no palpable masses. No guarding or rebound
Extremities: no edema, redness or tenderness in the calves or thighs, tophi over elbows, L wrist incision CDI
Skin: Skin color, texture, turgor normal. No rashes or lesions

1. FILL IN THE BLANK.
   Enter the proper code(s) in the blank(s) provided. If a specific category of code is not applicable, please leave the box blank. When entering multiple codes in the same box, separate them with a comma and a space (i.e. E11.9, I10). For each diagnosis code, add the applicable POA indicator, in parentheses, following the code, for example E11.9(Y). There is no POA indicator assigned for the Admit diagnosis.

   Z codes may be used as either a first-listed (principal diagnosis code in the inpatient setting) or secondary code, depending on the circumstances of the encounter. There is a list of Z codes that may only be principal/first-listed diagnosis in the Coding Guidelines. This means that they are not appropriate in a secondary position. If a Z code is the Admit and/or Principal Diagnosis position, please list them in the appropriate boxes. If however a Z code is not a principal/first-listed diagnosis, enter it in the Z Code box. External cause codes are never listed as the Admit/Principal Diagnosis. Any External cause codes will be listed in the External cause of morbidity code(s) box.

   1. Admit Diagnosis Code:

   5. External Cause of Morbidity Code(s):

Answer 1

Answer :

* Admit diagnosis code is for Renal failure : " N17. 9 " is the used for reimbursement purpose.

It is diagnosis code for renal failure.

* Secondary ICD10 CM codes :

1. Heart replaced by transplantation : Z94.1.

2. Sinus node dysfunction : I49. 5.

3. Hypertension : I15.9.

4. Hyperlipidemia : E78.5

5.Type 2 diabetis mellitus : E11.65.

6. Hypomagnisemia : E83.42.

7. Systolic heart failure : I50.2.

8. Right bundle branch block : I45.10.

9. Morbid obesity : E66.01.

10.cellulitis of forearm left :

11. Congestive heart failure NYHA class 2 pace maker : I50.2.

12. Long term current use of systemic steroids : Z79. 52.

13. Long term use of immuno suppression medication : Z79. 899.

Z code is the principle diagnosis code that is " N17. 9 ".

External code of morbidity codes : N29.1.
