Blood pressure and weight, with proteinuria followed by laboratory.

CMS chronic condition · CCW category: Chronic Kidney Disease · Devices: Blood pressure cuff, Connected weight scale

This family runs to 148 codes that differ mainly by anatomic site and laterality, which does not change whether the condition supports care management. The codes are not listed one by one here.

Clinical Context

Why nephrology practices benefit from RPM.

Nephrology patients require close monitoring of blood pressure and fluid balance. RPM enables daily weight and BP tracking that is critical for CKD management, especially in stages 3–5 where fluid overload can rapidly lead to hospitalization.

FAQ

Common questions.

01

What ICD-10 codes qualify nephrology patients for RPM?

CMS publishes no list of codes that qualify a patient for RPM: eligibility turns on the condition and on documented medical necessity. For nephrology, 48 billable ICD-10-CM codes cover the conditions RPM manages, spanning 5 conditions including essential hypertension, hypertensive heart and kidney disease, chronic kidney disease and esrd, glomerular and tubulo-interstitial kidney disease, transplant status and long-term drug therapy.

02

How does CCN Health support nephrology practices with RPM?

CCN Health provides turnkey RPM services for nephrology practices, including patient eligibility identification, enrollment documentation, device provisioning, clinical monitoring, and full Medicare billing support.

03

What is the revenue potential for RPM in nephrology?

Reimbursement varies by locality and payer contract, so see the RPM billing guide for current figures. Nephrology practices with a high prevalence of these conditions generally see the most benefit, particularly when RPM is combined with RPM and BHI for patients whose needs are distinct enough to document separately.

Sources & Compliance

Code set. Every code on this page is drawn from the official ICD-10-CM ICD-10-CM FY2026 (valid 2025-10-01 through 2026-09-30) released by CDC/NCHS, and only codes flagged valid for submission are listed. ICD-10-CM is published by the federal government and is in the public domain, so the descriptions here are the official long descriptors reproduced verbatim rather than summarized. The next code set, ICD-10-CM FY2027 (valid from 2026-10-01), is already reflected in the change flags.

Eligibility is not a code list. CMS does not publish a list of ICD-10 codes that qualify a patient for RPM, CCM, PCM, BHI, or RTM. Eligibility turns on the condition and on documented medical necessity. The programs shown against each condition are CCN Health’s clinical assessment of which programs that condition can support, not a statement of CMS approval.

Risk adjustment. HCC labels and category assignments come from the CMS-HCC V28 model for the 2026 payment year. Risk adjustment depends on the full encounter record, not on a single code, and the flags here are a prompt to check specificity rather than a payment guarantee.
