Occlusal guards are coded by type: D9944 for a hard full-arch appliance, D9945 for a soft full-arch appliance, and D9946 for a hard partial-arch appliance. Coverage varies widely, and payers that do cover them usually want to see a documented reason, most often bruxism, supported by clinical findings. Even when the patient is paying out of pocket, the findings are your baseline for judging whether the guard is working.
What to document at the diagnosis visit
- Symptoms the patient reports. Morning jaw soreness, headaches on waking, tooth sensitivity, a partner who hears grinding, clenching during the day.
- Clinical signs. Attrition and wear facets, abfractions, fractured cusps or restorations, masseter hypertrophy, linea alba, a scalloped tongue.
- TMJ findings and maximum opening. Clicking, crepitus, deviation, muscle tenderness, and an opening measurement. This is your baseline if symptoms change.
- The diagnosis. Sleep bruxism, awake bruxism, or a temporomandibular disorder. This is what ties the findings to the appliance.
- The appliance type and arch, matched to the CDT code.
- Records taken: digital scan, impressions, bite registration.
What to document at delivery
- Fit: seats fully, retention adequate, internal adjustments if needed.
- Occlusion: even contacts verified, guidance established, adjustments made.
- Instructions: when to wear it, cleaning, storage, and bringing it to recall visits.
- Follow-up: a fit check in a few weeks, or at the next recall.
When to refer
Grinding and clenching sometimes come with snoring, daytime sleepiness, or observed pauses in breathing. If you see those signs, record that you discussed them and whether you recommended the patient see their physician. An occlusal guard isn't a treatment for sleep apnea. A note showing you considered it and referred is better than silence.
Example: diagnosis and delivery
Records visit: Patient reports morning jaw soreness and headaches on waking; partner reports grinding. Clinical signs: generalized attrition/wear facets on canines and incisors, abfractions #12 and #13, linea alba. TMJ: clicking on the right, no pain; maximum opening 46mm. Diagnosis: sleep bruxism. Appliance: hard full-arch occlusal guard (D9944), maxillary. Records: digital scan and bite registration. Follow-up: delivery in 2 weeks.
Delivery: Fit: seats fully, retention adequate. Occlusion: even bilateral contacts verified with articulating paper, canine guidance established. Instructions: wear nightly, brush the guard with cool water, store dry in the case, avoid hot water, bring the guard to recall visits. Follow-up: check fit in 2–4 weeks.
Keep it in the record at recall
At later recall visits, a sentence on whether the patient is wearing the guard, the guard's condition, and whether symptoms improved closes the loop. It also supports a replacement when the guard wears through.
Capture the findings as you talk them through
ProphyNotes listens to the exam and the conversation and writes the bruxism findings, diagnosis, and appliance details into a structured note.
