Dysphagia Billing for SLPs: CPT 92610 and 92611 Medicare Documentation Guide
Dysphagia evaluation is one of the higher-reimbursing SLP services billed to Medicare — and one of the most documentation-intensive. If you're evaluating swallowing disorders in your practice, getting 92610 and 92611 right isn't just about revenue — it's about surviving a post-payment review when one inevitably comes.
92610 vs. 92611: What's the Difference?
These two codes cover different levels of dysphagia evaluation:
- 92610 — Evaluation of oral and pharyngeal swallowing function. This is the clinical (bedside) swallowing evaluation — no instrumental assessment involved. It covers oral mechanism examination, trial swallows with various consistencies, and clinical judgment about swallowing safety and efficiency.
- 92611 — Motion fluoroscopic evaluation of swallowing function by cine or video recording. This is the instrumental evaluation — the Modified Barium Swallow Study (MBSS) or videofluoroscopic swallowing study (VFSS). It requires radiology facilities and produces objective imaging data.
Key distinction: 92610 and 92611 are not hierarchical. You don't bill 92610 as a "lower level" of 92611. They describe fundamentally different procedures. A clinical bedside eval is 92610. An instrumental study is 92611. Billing both on the same date of service is permissible when both are performed and documented separately — but the documentation must clearly show two distinct evaluation procedures, not one evaluation with two codes.
Documentation Requirements for 92610
CMS guidance indicates that 92610 documentation should include:
- Reason for referral — why the swallowing evaluation was ordered, including relevant medical history (stroke, head/neck cancer, neurological conditions, etc.)
- Oral mechanism examination — findings regarding oral motor strength, range of motion, coordination, sensation, and structural integrity
- Trial swallows — specific food/liquid consistencies trialed, volumes, and patient response to each trial (including signs of aspiration or penetration)
- Clinical impression — your professional assessment of swallowing safety and efficiency based on the clinical exam
- Recommendations — diet modifications, compensatory strategies, need for instrumental assessment, and/or treatment plan
The most common documentation failure on 92610 claims: insufficient detail on trial swallows. Writing "patient tolerated thin liquids and solids without difficulty" doesn't support a comprehensive clinical evaluation code. Auditors expect specific consistencies, volumes, and observations for each trial.
Documentation Requirements for 92611
For the instrumental evaluation, documentation requirements are more extensive:
- Clinical indication — why an instrumental study was necessary (what questions the clinical eval couldn't answer)
- Barium consistencies tested — specific bolus types, volumes, and modifications trialed during the study
- Anatomic and physiologic findings — oral phase, pharyngeal phase, and esophageal observations
- Penetration/aspiration findings — if applicable, with Penetration-Aspiration Scale scoring
- Compensatory strategy trials — any postural changes, swallow maneuvers, or consistency modifications tested during the study and their effectiveness
- Interpretation and recommendations — diet level recommendations, treatment plan, and follow-up timeline
- Report distribution — documentation that the report was provided to the referring physician
Common Billing Mistakes on Dysphagia Claims
1. Billing 92611 without radiology facility documentation
92611 requires fluoroscopic imaging. If you're performing what you call an MBSS but don't have documentation of fluoroscopic recording, the claim doesn't survive review. Some SLPs have attempted to bill 92611 for Fiberoptic Endoscopic Evaluation of Swallowing (FEES) — this is incorrect. FEES has its own code (31575) and is typically billed by the physician performing the endoscopy.
2. Billing both 92610 and 92611 without distinct documentation
If you perform a bedside evaluation and an instrumental study on the same date, you can bill both — but the documentation must show two clearly separate evaluation procedures with independent findings. A single note that blends both into one narrative will get one of the two codes denied.
3. Missing the -GN modifier
Both 92610 and 92611 require the -GN modifier when billed by an SLP to Medicare Part B. This is a common miss because dysphagia evaluations feel "medical" rather than "therapy" — but they're still SLP services under Medicare's classification.
4. Billing 92610 for a simple swallow screening
A swallow screening (pass/fail assessment to determine if a full evaluation is needed) is not the same as a clinical swallowing evaluation. Billing 92610 for a 5-minute bedside screen is upcoding. If you performed a screening that took 10 minutes rather than a comprehensive clinical evaluation, 92610 is not the appropriate code.
NCCI Edits Affecting Dysphagia Codes
The National Correct Coding Initiative (NCCI) has specific edit pairs that affect dysphagia billing. Be aware of:
- 92610 and 92507 on the same date — if you perform a clinical swallowing evaluation and provide treatment on the same visit, modifier documentation is critical
- 92611 and 92612/92613 — bundling rules apply; check current NCCI tables for your MAC
NCCI edit pairs are updated quarterly. What was billable together last quarter may be bundled this quarter — which is why ongoing monitoring matters.
Dysphagia billing rules change with every NCCI update.
SLPBillingClarity tracks NCCI edit pairs, documentation requirements, and audit signals for dysphagia codes every month.
