TL;DR: The Centers for Medicare & Medicaid Services modified NCD 202, its National Coverage Determination governing uroflowmetric evaluations, effective March 7, 2026. Here's what billing teams need to know.
CMS updated NCD 202 to affirm Medicare coverage of uroflowmetric evaluations — also called urodynamic voiding studies or urodynamic flow studies — for diagnosing urological dysfunctions including bladder outlet obstructions. The policy does not list specific CPT or HCPCS codes, which creates a documentation burden your billing team needs to plan for now, before March 7, 2026. This post covers everything currently published in the CMS policy for urology billing teams, RCM managers, and practice administrators handling Medicare claims.

CMS Uroflowmetric Evaluations Coverage Criteria and Medical Necessity Requirements 2026
NCD 202 is the National Coverage Determination that governs whether Medicare will reimburse uroflowmetric evaluations — the clinical term for urodynamic voiding or urodynamic flow studies used to assess how well the bladder and urethra are storing and releasing urine. The modified coverage policy affirms that these studies are covered under Medicare's Diagnostic Tests benefit category when used to diagnose various urological dysfunctions, including bladder outlet obstructions.
The medical necessity threshold here is diagnostic intent. CMS isn't covering uroflowmetry as a routine screening tool. The study must be ordered to diagnose a specific urological dysfunction — the documentation in the claim needs to reflect that clinical purpose directly.
The policy does not specify prior authorization requirements, which is consistent with most diagnostic test NCDs. That said, absence of a prior auth requirement doesn't mean your claims are low-risk. Medical necessity documentation is your primary defense against claim denial on these services. If the ordering diagnosis isn't clearly documented and linked to the study in your clinical notes, you're exposed.
One thing worth flagging: CMS explicitly notes that NCD 202 may not cover every applicable Medicare benefit category for uroflowmetric evaluations. That's a signal to review whether any secondary benefit categories apply to your patient mix — particularly if you're billing in a hospital outpatient setting versus a physician office.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Diagnosing bladder outlet obstruction | Covered | Not specified in policy | Medical necessity documentation required |
| Diagnosing various urological dysfunctions | Covered | Not specified in policy | Diagnostic intent must be documented in the clinical record |
CMS Uroflowmetric Evaluations Billing Guidelines and Action Items 2026
The honest read on this policy modification is that CMS isn't dramatically expanding or restricting coverage — it's clarifying and reaffirming the existing framework. But "modification" still means your billing team needs to review current workflows before March 7, 2026.
Here's what to do:
| # | Action Item |
|---|---|
| 1 | Audit your urodynamic study documentation now. Pull a sample of uroflowmetry claims from the last 90 days. Check that every claim has a clear diagnosis code linked to a urological dysfunction and that the clinical notes support the diagnostic intent of the study. Do this before March 7, 2026, so you know where your exposure is. |
| 2 | Confirm your charge capture reflects the covered indications. The CMS uroflowmetric evaluation coverage policy covers studies performed for diagnosis — not surveillance or routine monitoring. If your charge capture process doesn't flag the distinction between diagnostic and non-diagnostic orders, fix that workflow before the effective date. |
| 3 | Identify which CPT codes your practice uses for urodynamic flow studies. NCD 202 does not list specific codes, so your billing team needs to know which codes you're billing and verify they fall under the Diagnostic Tests benefit category. This is a gap in the policy that creates real claim denial risk if your coders are working from assumptions. |
| 4 | Review your claim denial history for uroflowmetry. If you've seen denials on urodynamic voiding studies in the past 12 months, this policy modification is worth reviewing against those denial reasons. A documented CMS coverage affirmation can support your appeals. |
| 5 | Talk to your compliance officer if you bill across multiple settings. The policy's note that NCD 202 may not cover all applicable benefit categories is particularly relevant if you're billing in hospital outpatient, ASC, or physician office settings. Each setting can have different reimbursement rules layered on top of the NCD. If you're not sure how this applies to your billing mix, loop in your compliance officer before March 7, 2026. |

CPT, HCPCS, and ICD-10 Codes for Uroflowmetric Evaluations Under NCD 202
Covered CPT Codes (When Medical Necessity Criteria Are Met)
The CMS policy for NCD 202 does not list specific CPT or HCPCS codes. This is notable — and it matters for your billing team.
When a CMS NCD doesn't enumerate codes, the practical implication is that claims are evaluated based on the broader benefit category (Diagnostic Tests, in this case) combined with medical necessity documentation. Your coding team should identify which CPT codes they're currently using for uroflowmetric evaluations and cross-reference those codes against CMS's Diagnostic Tests benefit category to confirm alignment.
Because no codes are specified in the policy data for NCD 202, no code table is included here. Do not assume any code is automatically covered or excluded based on this policy alone — that determination depends on your specific codes and documentation.
Not Covered / Experimental Codes
NCD 202 does not designate any uroflowmetric evaluation codes or indications as experimental or non-covered. No exclusions are listed in the current policy.
Key ICD-10-CM Diagnosis Codes
NCD 202 does not enumerate specific ICD-10-CM codes. The policy references urological dysfunctions and bladder outlet obstructions as the covered diagnostic targets. Your coding team should select ICD-10-CM codes that accurately reflect the documented urological dysfunction being evaluated — and those codes should match the physician's stated reason for ordering the study.
If you need ICD-10 code guidance for urodynamic studies, that's a separate coding question that falls outside what this NCD specifies. Talk to your coding consultant or refer to the CMS Claims Processing Instructions cross-referenced in the policy.
