This page describes products and general use; it is not medical advice.
Three HCPCS Level II codes describe blood pressure measuring equipment: A4660 (a manual kit with cuff and stethoscope), A4663 (a cuff only) and A4670 (an automatic monitor). The right one depends on what the product actually is, which makes this a lookup task for clinic billing staff, supplier staff and buyers writing or checking an order. For what the devices are and how they differ clinically, see what a blood pressure cuff is and the aneroid sphygmomanometer.
Which blood pressure monitor HCPCS code matches which product?
HCPCS Level II is the code set used mainly to identify products, supplies and services not included in the CPT codes, such as durable medical equipment, prosthetics, orthotics and supplies furnished outside a physician’s office. CMS maintains it and decides additions, revisions and deletions (CMS, HCPCS page, checked 2026-11-01). If you need the difference between HCPCS and CPT, see HCPCS vs CPT codes; for another worked code lookup, see the CAM boot HCPCS code guide.
| Code | Descriptor | Product it fits | Source |
|---|---|---|---|
| A4660 | Sphygmomanometer/blood pressure apparatus with cuff and stethoscope | A manual kit: gauge, cuff and stethoscope together | CMS ESRD PPS consolidated billing list, CY 2025 |
| A4663 | Blood pressure cuff only | A replacement cuff sold without the rest of the apparatus | CMS ESRD PPS consolidated billing list, CY 2025; Illinois HFS notice (2020) |
| A4670 | Automatic blood pressure monitor | A self-contained automatic monitor | Illinois HFS notice (2020); NC Medicaid Special Bulletin COVID-19 #29 (2020) |
Blood pressure cuff HCPCS code: A4663
A4663 is “blood pressure cuff only”. It applies when the cuff is the item being supplied. A cuff sold inside a kit is part of the kit code, A4660, rather than a separate line. For cuff types and sizing concepts, read the cuff guide.
HCPCS code for a blood pressure monitor (automatic): A4670
A4670 is “automatic blood pressure monitor”. Two state Medicaid sources in 2020 use this descriptor: Illinois lists it among the codes for a blood pressure monitoring kit, and North Carolina Medicaid added coverage of A4670 effective March 30, 2020. Whether a given device is accepted for a given patient or payer is a payer question, not something the code settles. For how monitors are validated, see validated blood pressure monitors.
Who gets billed: the ESRD consolidated billing list
CMS publishes a list of items and services subject to the End-Stage Renal Disease Prospective Payment System consolidated billing. Under the heading “DME ESRD supply HCPCS not payable to DME suppliers”, the CY 2025 list includes A4660 (sphygmomanometer/blood pressure apparatus with cuff and stethoscope) and A4663 (blood pressure cuff only). CMS states the list is not all-inclusive. In plain terms, for a patient in that dialysis context these supplies are bundled into the facility’s payment instead of being billed separately by a DME supplier. This page does not extend that rule to other patients or payers (CMS, checked 2026-11-01).
Benefit limits: one state’s example
Illinois Medicaid (HFS Provider Notice, July 1, 2020, “Blood Pressure Monitoring Kit”) shows how a payer can attach limits to these codes. This is one state’s 2020 notice and may have changed.
| Code | Illinois benefit limit |
|---|---|
| A4660 | 1 per 365 days |
| A4663 | 1 per 365 days |
| A4670 | 1 per 1,825 days |
The same notice says a health care provider may order the kit, including the appropriately sized cuff, from a durable medical equipment provider; there are no participant copayments for durable medical equipment; prior approval is not required within the limits; and a replacement before the limit needs prior approval for traditional Medicaid, or contact with the health plan for managed care participants.
North Carolina Medicaid’s 2020 bulletin, by comparison, added coverage of A4670 effective March 30, 2020, which it said could be provided without prior authorization, with suppliers keeping the usual documentation of medical necessity and all claims subject to audit.
What to confirm before ordering or billing
- That the product description matches one code descriptor exactly: kit (A4660), cuff only (A4663) or automatic monitor (A4670).
- The payer’s current quantity or frequency limit for that code.
- Whether the payer requires an order from a provider and what medical-necessity documentation the supplier must keep.
- The payer’s rule for replacing equipment before the limit.
- That the code is still valid: CMS issues quarterly HCPCS update files.
The device itself is a separate question from the code. For checking a monitor’s accuracy over time, see calibration of a blood pressure monitor.
Common mistakes
- Billing a cuff bought as part of a kit under the cuff-only code, or the reverse.
- Assuming the limits in one state’s notice apply everywhere.
- Treating a code as proof of coverage; the code identifies the item and the payer decides coverage.
