Dental claims for deep cleaning are some of the easiest to deny and one of the hardest to “fix later” if the notes are thin. Many practices do the clinical work correctly, but still get pushback because the payer thinks it was a regular cleaning, the wrong quadrant count, or the wrong code selection. This blog breaks down the d4341 dental code in plain English so you can document it cleanly, bill it correctly, and reduce avoidable denials. For the ADA’s payer-focused guidance on using SRP codes and what to send when multiple quadrants are treated, reference the ADA resource here.
The procedure code d4341 is used when you perform periodontal scaling and root planing (SRP) on four or more teeth in a single quadrant. In simple terms, this is deep cleaning below the gumline in one quadrant, done as treatment for periodontal disease, not as a routine preventive cleaning. Many payer policies describe SRP as therapeutic, not prophylactic.
Clinically, SRP is typically chosen when the patient has findings consistent with periodontitis and the care plan includes removing subgingival deposits and smoothing root surfaces so the gums can heal.
People sometimes search for the d4341 cpt code, but D4341 is a CDT dental procedure code, not a CPT code. You might still see “CPT” used casually in offices, but on dental claims, you are reporting CDT codes.
D4341 generally covers SRP performed in one quadrant when four or more teeth are treated in that quadrant. Payers commonly define SRP as instrumentation of crown and root surfaces to remove plaque and calculus and to treat periodontal disease. Here is what “covers” usually means in real-world billing terms:
The d4342 dental code is SRP for one to three teeth per quadrant. The core idea is the same, but the number of teeth treated in that quadrant changes the code selection.
This is where most problems happen. Below are the rules that tend to trigger denials, audits, or refund requests when missed.
Common mistake: Billing D4341 when only one to three teeth in the quadrant truly meet SRP criteria, or when the notes do not clearly support which teeth were treated.
When you report SRP in more than two quadrants in a single visit, it often triggers a request for additional documentation. The ADA specifically notes that reporting SRP for more than two quadrants in one visit will usually lead to a request for items like full mouth periodontal charting, full mouth X rays, diagnosis, and the treatment plan.
Common mistake: Sending the claim with no perio charting, no diagnostic support, and no treatment plan narrative, then scrambling after the denial.
Different carriers phrase criteria differently, but they commonly want to see proof of active periodontal disease, not just “heavy tartar.”
A Medicaid program example (ForwardHealth Wisconsin) ties approval to periodontal charting and pocket measurements, along with radiographic support such as visible calculus and other supporting criteria.
Common mistake: The clinical narrative says “deep cleaning needed” but does not include periodontal findings, tooth or quadrant detail, or why SRP was necessary.
Some payer documentation guidance points out that periodontal maintenance (often D4910) already includes site-specific scaling and root planing by definition.
Common mistake: Trying to bill SRP when the clinical story reads like maintenance, or scheduling SRP too close to prior SRP without a clear reason and plan.
Many payers allow multiple quadrants, but they may expect SRP to be performed across appointments, especially when anesthesia and time are involved. One Medicaid example limits SRP to two quadrants per date of service in most circumstances, with specific exceptions that must be documented and approved.
Common mistake: Billing all four quadrants in one visit without including the documentation that explains why and without attaching the charting and treatment plan upfront.
Use D4341 only when it truly matches the care delivered and documented. D4341 is generally not appropriate in situations like these:
Every payer is different, so always check the plan’s provider guide. Still, a few requirements show up again and again across carriers and programs:
Based on ADA guidance and payer policies, be ready to submit:
Some payer documentation guidelines state that for D4341, the quadrant must include at least four teeth with periodontitis, while D4342 is appropriate for a partial quadrant with one to three teeth with periodontitis.
Some payers do not require prior authorization for SRP but may recommend it for full mouth, four-quadrant SRP, and may want estimates for time per quadrant when submitting documentation.
Plans often limit how often SRP is payable per quadrant within a time period. Because this varies widely, treat it as a benefits check item. If a patient had SRP recently, include a clear rationale and updated periodontal findings if you are appealing or requesting an exception.
Here is a clean way to think about an SRP case that supports D4341, without overcomplicating the record.
Why this bills as D4341: The service is SRP; it is per quadrant, and the treated quadrant includes four or more teeth meeting SRP criteria, aligning with common payer definitions and documentation expectations.
D4341 is not a “deep cleaning” shortcut code. It is a specific periodontal therapy code that must match the quadrant tooth count and be backed by periodontal findings, a diagnosis, and a clear plan. If you treat more than two quadrants in one visit, assume you may need to attach fuller documentation up front, because that is a known trigger for payer review.
If your team masters the documentation pattern once, D4341 billing becomes predictable: correct code selection, clear perio support, and fewer denials that waste chairside and admin time.

It depends on the plan’s frequency rules and medical necessity. Many plans limit SRP coverage within a time period per quadrant, so confirm benefits and document updated periodontal findings if repeat SRP is clinically necessary.
Follow the payer’s SRP rules, attach documentation proactively when you know the claim will be reviewed, and make sure the tooth count per quadrant matches the code. Also avoid mixing SRP language with routine cleaning language in your notes.
Yes, many carriers apply frequency limits, quadrant limits per date of service, and documentation requirements. For example, some programs typically limit SRP to two quadrants per date of service unless an exception applies and is documented.
Common requirements include periodontal charting, radiographs, periodontal diagnosis, and the treatment plan. Many payers request more documentation when SRP is billed for more than two quadrants in one visit.
Use D4342 when SRP is performed on one to three teeth in a quadrant. This is the key point in d4341 vs d4342 selection.
