Aetna · Type 2 diabetes with chronic kidney disease · Updated May 25

Aetna prior authorization letter for Type 2 diabetes with chronic kidney disease.

A defensible, plan-specific letter template for Ozempic (semaglutide) or Mounjaro (tirzepatide). T2D with CKD is one of the most defensible PA paths under the ADA Standards of Care and the KDIGO guidelines, which name GLP-1 RA as a preferred therapy for renal protection.

Plan note: Aetna requires documented BMI greater than or equal to 30, or BMI greater than or equal to 27 with at least one comorbidity (T2D, hypertension, dyslipidemia, OSA). Six months of documented dietary intervention. Aetna prefers Wegovy for obesity indication. Step therapy may apply (phentermine, orlistat tried first under some plan formularies).
What CVS Caremark actually requires

Aetna contracts pharmacy benefit administration to CVS Caremark, which adjudicates this PA. The criteria below are pulled from the publicly posted PBM clinical policy. Match each item before you send.

  • BMI greater than or equal to 30, OR BMI greater than or equal to 27 with at least one weight-related comorbidity (T2D, hypertension, dyslipidemia, OSA)
  • Documented six-month lifestyle intervention or prior anti-obesity medication trial
  • Step therapy through phentermine or orlistat (or documented contraindication / intolerance)
  • Treatment plan including continued lifestyle counseling and 5 percent weight-loss target at 6 months
  • Reauthorization requires documented adherence and ≥5 percent weight loss from baseline at 12 months

To the Aetna Prior Authorization Reviewer,

I am the treating clinician for [Patient name]. I am writing to request prior authorization for Ozempic (semaglutide) or Mounjaro (tirzepatide) for treatment of Type 2 diabetes with chronic kidney disease (ICD-10: E11.22, N18.3, N18.4, N18.5, N18.6).

Clinical justification

The KDIGO 2022 Clinical Practice Guideline for Diabetes Management in CKD names GLP-1 receptor agonists as a preferred second-line agent (after metformin and SGLT2 inhibitors) for patients with T2D and CKD, citing demonstrated renal-outcome benefit. The FLOW trial (semaglutide in T2D and CKD), published in NEJM in May 2024, randomized 3,533 adults with T2D and CKD (eGFR 25 to 75) to semaglutide 1.0 mg or placebo and demonstrated a 24 percent reduction in the composite kidney outcome (kidney failure, sustained eGFR decline of 50 percent or more, kidney or cardiovascular death) over a median 3.4 years. The ADA 2026 Standards of Care recommend GLP-1 RA independent of A1c for patients with T2D and CKD.

Patient-specific findings

  - [Insert current measurements: weight, height, BMI, blood pressure]
  - [Insert relevant lab values with dates: A1c, lipid panel, kidney function]
  - [Insert documentation of comorbidities with ICD-10]
  - [Insert documentation of prior treatment history, including any prior GLP-1 trials, anti-obesity medication trials or lifestyle intervention]

Criteria met per Aetna policy

This request meets the criteria set out in Aetna Clinical Policy Bulletin 0040 (Obesity Treatment) and 0040 (Anti-Obesity Medications):

  - Diagnosis of T2D documented with ICD-10 E11.22 (T2D with diabetic chronic kidney disease) or E11.x plus N18.x
  - Most recent eGFR and urine albumin-to-creatinine ratio (UACR), with dates drawn
  - CKD stage documented (N18.3 = stage 3, N18.4 = stage 4, N18.5 = stage 5, N18.6 = ESRD)
  - Current A1c (within the past 90 days)
  - Nephrology consult letter or documentation of nephrology co-management (strengthens but not always required)

Supporting evidence

The clinical case for Ozempic (semaglutide) or Mounjaro (tirzepatide) in this indication is supported by the following registration trials and outcomes data:

  - FLOW (semaglutide in T2D and CKD), Perkovic et al., NEJM 2024, DOI 10.1056/NEJMoa2403347
  - SUSTAIN-6 (semaglutide cardiovascular outcomes in T2D, included renal subgroup), Marso et al., NEJM 2016
  - AMPLITUDE-O (efpeglenatide in T2D with CV or kidney disease), Gerstein et al., NEJM 2021

Plan-specific note

Aetna requires documented BMI greater than or equal to 30, or BMI greater than or equal to 27 with at least one comorbidity (T2D, hypertension, dyslipidemia, OSA). Six months of documented dietary intervention. Aetna prefers Wegovy for obesity indication. Step therapy may apply (phentermine, orlistat tried first under some plan formularies).

Requested action

I am requesting prior authorization for Ozempic (semaglutide) or Mounjaro (tirzepatide) at the [insert starting dose] starting dose, with planned titration per FDA labeling. I am also requesting that this authorization be granted for a continuous 12-month period subject to documented clinical response, per standard formulary practice.

If additional information is required, please contact me directly at [Prescriber phone] or [Prescriber email]. I am available to discuss this case with your medical director if helpful.

Thank you for your attention to this request.

Sincerely,

The denial reasons to preempt

Most denials of this combination cite one of the reasons below. Address each one in the patient-specific findings section before you send. If the plan denies anyway, the appeal letter cites the same evidence with the denial reason added in the opening paragraph.

  • eGFR not documented or older than 90 days
  • PA submitted for Wegovy or Zepbound (obesity-indication brands) rather than Ozempic or Mounjaro (the T2D brands of the same molecule)
  • Plan asks for SGLT2 inhibitor trial first; cite KDIGO 2022 which allows either drug class as second-line for CKD
