  1. ICD 10 and Nephrology Jeff Kaufhold, MD FACP Nephrology Associates of Dayton Oct 2013

  2. Make the Diagnosis of Kidney Disease • Criteria The ICD9 Code for CKD is 585.x where x = stage The ICD 9 Code for ARF is 584.9 • Decreased kidney function eGFR of <60 ml/min/1.73 m2 for ≥ 3 months • Abnormal urinalysis including the presence of proteinuria or hematuria • Request a spot urine protein/creatinine ratio (Normal is <30 mg/g) • Document an abnormal Renal Imaging Study

  3. ICD 9 and 10 history • ICD 9 developed by WHO • ICD 9 Clinical Modification developed for US in 1979. • CPT (clinical Procedural Terminology) codes used for ambulatory reporting. • ICD 10 developed in 1990’s • ICD 10 codes are now available in EPIC as of Oct 1 2013 • Mandatory use of ICD 10 is Oct 1, 2014. • CPT codes will continue to be used for physician practice settings/ office billing

  4. ICD 10 after Oct 1 2014 • Required for HIPAA transactions • ICD 10 CM (Diagnosis) codes Required for diagnosis of all services inpt or outpt • ICD 10 PCS (procedure) codes will be required on inpt claims • EPIC is starting the migration from ICD 9 to 10 codes now, and EPIC Premier inpt billing function includes the new ICD 10 coding structure.

  5. ICD 10 Changes Over 50% of new Dx are musculoskel, and 36 % are to distinguish R from L

  6. ICD 10 Changes • Up to 7 characters • Includes complication, severity, sequelae and other disease related parameters • Includes laterality • Includes initial or subsequent encounter code • Improved consistency of terminology • Combination codes are common i.e DM 2, controlled with renal manifestation • Has space holders for expansion

  7. ICD 10 PCS coding for inpts ICD 9 ; 45.16 EGD with excisional biopsy, ICD 10 0DB58ZX Endoscopic esophageal excision via natural or artificial opening

  8. Most common issues in ICD 10 • Laterality – as you code, EPIC will prompt you if right or left is required • Trimester specific • Many new orthopedic codes • Specificity is increased dramatically, so physician documentation must be more specific too.

  9. Top 5 Clinical Documentation Issues • CHF • Sepsis • Renal Failure • Pneumonia • Respiratory Failure • Don’t use “Other” or accept a nonspecific diagnosis like DM, when a more specific term exists: • “DM 2 controlled with renal manifestation”

  10. ICD 10 codes • Epic is migrating codes so over next year you may search using known ICD 9 codes • Can keep your PMHx and ongoing problem list NONSPECIFIC, • But your visit diagnosis list must be as specific, detailed, and include as many modifiers/ comorbidities/severity codes as possible

  11. Common Diagnoses • ICD 9 • 250.02 DM 2 no mention of controlled or complication • 250.43 DM 1 with renal manifestation • ICD 10 • E11.65 DM 2 with hyperglycemia • E10.21 DM 1 with nephropathy AND • E10.65 DM1 with hyperglycemia

  12. Top 5 Clinical Documentation issues

  13. Quality Performance hinges on Documentation • For inpts affects the hospital quality score • For our pts affects our practice score • Lack of clear documentation results in inappropriate assignment of complication codes for expected consequence of renal disease • Improved documentation results in lower reported complication rates, • higher complexity/ comorbidity scores reflect sicker population we care for.

  14. Specific details for ptswith ARF and CKD • DM Type I or II, controlled or uncontrolled • Use A1c over 6.5 as uncontrolled • With renal manifestation • Hypertension • With nephropathy • CKD stages 1-5, use ESRD for pts on dialysis in the medicare ESRD program. • AKI with ATN

  15. Specific details for ptswith ARF and CKD • AKI with ATN • Urine findings ATN casts • Oliguria • Creatinine over 2.5 or > 2X baseline • Were they pre-renal? • Does pt have TIN? • Complications of renal failure • Anemia of CKD • Secondary hyperparathyroidism of renal origin • Protein calorie malnutrition Severe = albumin less than 3.0

  16. Estimated impact on physician practice • 10 -20 % increase in denials • Differences in authorization and referral triggers • Increased scrutiny of documentation • Impact on contracting/ preferred provider status based on severity of illness as reflected in coding.

  17. ICD 10 and EPIC • ICD 10 diagnosis calculator goes live on Premier Epic Oct 28 2013 • Training modules available on Healthstream • Some codes require specific information, and a coding window will open to fill in R vs L, initial visit vs followup, sequelae. • Many codes won’t require more specificity, but for visits we should try to be as specific as possible.

  18. ICD 10 and EPIC • Many codes won’t require more specificity, but for visits we should try to be as specific as possible. • We can double click item on the problem list like DM, HTN, Other disorder of renal etc, and make it more specific, without losing / deleting associations.

  19. Diabetes codes • E08.22 DM due to underlying condition with diabetic nephropathy • E09.22 Drug or chemical induced DM with DM CKD • E10.22 DM I with Diab. Neph • E11.22 DM II with Diabetic Nephropathy • E13.22 Other specified DM with Diabetic CKD

  20. CKD Codes • N18.1 CKD stage 1 • N18.2 CKD Stage 2 • N18.3 CKD Stage 3 • N18.4 CKD Stage 4 • N18.5 CKD stage 5 • N18.6 ESRD • N18.9 CKD unspecified

  21. CKD and DM codes • Code the DM first, then the stage: • E10.22 Type I DM with nephropathy • N18.6 ESRD • Same for Hypertensive Kidney Disease • I12 hypertensive Kidney disease • N18.4 CKD Stage 4 • If pt has heart and kidney disease, use • I13 hypertensive Heart and CKD • CHF uses I 50 codes

  22. HTN and CKD Codes • I12.0 Hypertensive CKD with Stage 5 or ESRD • I12.9 “”“” with stages 1-4 CKD • I13.10 Hypertensive Heart and CKD without heart failure, Stages 1-4 • I13.11 Hypertensive Heart and CKD without heart failure, Stage 5 or ESRD • I13.2 Hypertensive Heart and CKD with heart failure, Stage 5 or ESRD

  23. Nephrology Codes • N 0 – 8 Glomerulonephritis • N 10 Interstitial Nephritis • N 17 ARF • N 18 CKD • N 20 Kidney stone • N 30-39 Bladder disorders • N 40 BPH • ICD10Data.com

  24. Nephrology Codes • PCKD Q 61.3 • Acquired cyst N 28.1 • Q 60-64 Congenital Malformations of the urinary System • R 80 Proteinuria • R 81 Glycosuria • R 60 Edema • ICD10data.com

  25. Nephrology Codes for ICD 10 • Electrolyte disorders: E 87 • High K E 87.5 • Protein Calorie Malnutrition • E 43 severe • E 44 Mild to Moderate • Secondary hyperparathyroidism of renal origin • N 25.81

  26. Nephrology Common Codes • Anemia of CKD D 63.1 • Lupus Nephritis • SLE M 32 – not completely mapped yet • Renal transplant – has not yet mapped • (as of Oct 2013) • Dysfunction would be coded with the ARF or CKD code to denote pts renal function at time of visit • N 17.9 ARF • N 18.3 CKD stage 3

  27. Transplant Specifics • Just because your patient has a transplant, they still have Chronic Kidney disease. • List the transplant • List the CKD stage for chronic allograft dysfunction • List acute allograft dysfunction if present • List the cause of their underlying CKD/ESRD • List comorbidities and complications • Are they anemic due to Cellcept use? • Did they develop NODAT?

  28. PCKD specifics • PCKD Q 61.3 • Acquired cyst N 28.1 • Q 60-64 Congenital Malformations of the urinary System • Autosomal Dominant or recessive? • Liver /other cysts?
