Starting October 1, 2026, medical coders working in home health will have 19 new HCPCS Level II codes to watch for. The Centers for Medicare & Medicaid Services (CMS) is expanding the non-routine supply list under home health consolidated billing (HH CB) — and if you code for an agency, a supplier, or a physician practice that touches home health patients, this update directly affects how (and whether) you get paid for these supplies.
Here’s a plain-English breakdown of what’s changing, which codes are affected, and how consolidated billing rules apply so you can avoid denied claims.
Quick Refresher: What Is Home Health Consolidated Billing?
Home health consolidated billing is a Medicare rule that bundles payment for services under one roof. When a patient is under a home health plan of care that a physician has authorized, Medicare pays one agency — the home health agency (HHA) that filed the Notice of Admission — for essentially everything tied to that plan of care. This is called the primary HHA.
In practice, that means Medicare generally won’t pay a separate claim from another provider for services or supplies that fall under the patient’s HH plan of care, even if a different provider technically furnished them. The primary HHA is responsible for billing and, in turn, for reimbursing or coordinating with any other providers involved.
There are a few carve-outs where consolidated billing doesn’t apply:
- Therapy services performed directly by a physician
- Supplies that are incidental to a physician’s service
- Supplies furnished in an institutional setting
Everything else that falls under the scope of the home health benefit — skilled nursing, home health aide visits, physical therapy, speech-language pathology, occupational therapy, medical social services, and most medical supplies — typically gets bundled into that single HHA claim.
One important exception coders should always remember: durable medical equipment (DME) is not subject to HH CB. DME can still be billed separately outside the home health bundle.
What’s Actually Changing on October 1, 2026
CMS is adding 19 new HCPCS Level II “A” codes to the non-routine supply list that falls under consolidated billing. Most of these are supplies coders will recognize immediately — syringes, urinary and ostomy supplies, wound-related tape, and irrigation devices. Once these codes go live, billing them separately outside the primary HHA’s claim (for a patient under an active HH plan of care) will likely trigger a denial.
Here’s the full list:
| HCPCS Code | Description |
|---|---|
| A4206 | Syringe with needle, sterile, 1 cc or less, each |
| A4207 | Syringe with needle, sterile, 2 cc, each |
| A4208 | Syringe with needle, sterile, 3 cc, each |
| A4209 | Syringe with needle, sterile, 5 cc or greater, each |
| A4210 | Needle-free injection device, each |
| A4211 | Supplies for self-administered injections |
| A4218 | Sterile saline or water, metered dose dispenser, 10 ml |
| A4318 | Female external urinary collection cup, with or without ring attachment, per day |
| A4336 | Incontinence supply, urethral insert, any type, each |
| A4337 | Incontinence supply, rectal insert, any type, each |
| A4341 | Indwelling intraurethral drainage device with valve, patient inserted, replacement only, each |
| A4342 | Accessories for patient-inserted indwelling intraurethral drainage device with valve, replacement only, each |
| A4397 | Irrigation supply; sleeve, each |
| A4398 | Ostomy irrigation supply; bag, each |
| A4399 | Ostomy irrigation supply; cone/catheter, with or without brush |
| A4400 | Ostomy irrigation set |
| A4450 | Tape, non-waterproof, per 18 square inches |
| A4452 | Tape, waterproof, per 18 square inches |
| A4453 | Rectal catheter with or without balloon, for use with any type of transanal irrigation system, each |
Why This Matters for Coders and Billers
If you code claims involving supplies for patients receiving home health services, this update is worth flagging now, not in October. A few practical takeaways:
Check the HH CB status before billing. For any patient under an active home health plan of care, cross-reference these codes against your claim before submission. If a supplier or physician office bills one of these 19 codes for a patient who is under HH CB, expect the claim to be rejected or bundled back into the primary HHA’s payment.
DME still bills separately. Don’t confuse non-routine supplies with durable medical equipment. DME remains exempt from consolidated billing, so equipment claims aren’t affected by this update.
Watch for the narrow exceptions. Physician-performed therapy, supplies incidental to a physician visit, and supplies furnished in an institutional setting are still billable outside the HH bundle. Everything else tied to the plan of care generally isn’t.
Update your claim scrubbers and edits. If your organization uses claim-edit software or payer-specific logic to flag HH CB conflicts, make sure these 19 codes are added to that list before the October 1, 2026 effective date.
Where to Verify the Full Code List
CMS maintains the complete, authoritative list of codes subject to home health consolidated billing on CMS.gov. Since this list is updated periodically, it’s worth bookmarking and checking directly rather than relying solely on secondary sources — especially close to the effective date, in case of last-minute revisions.
The Bottom Line
This isn’t a sweeping overhaul of home health billing rules, but it is a meaningful expansion of the non-routine supply list that coders need to bake into their workflows before October 1, 2026. Getting ahead of it now — updating edits, briefing billing staff, and double-checking claims for these 19 codes — will save your team from a wave of denials once the change takes effect.
