Field glossary

What each placeholder represents.

Medical history reviewed/updates
Confirm RMH reviewed today and note any changes since the original procedure — anticoagulants, antibiotics, immunosuppressants, allergies, fever, or systemic symptoms.
BP/Pulse
Vital signs taken at the visit. Required if anesthesia or surgical management is contemplated; also a baseline if systemic symptoms (fever, tachycardia) suggest infection.
Original procedure
The CDT code and tooth/site of the originating surgery (e.g., 'D7140 extraction #30'). Anchors the by-report narrative.
Date of original procedure
Date the originating surgery was performed. Determines whether today's visit is inside or outside the global period — the single most-checked element on the claim.
Chief complaint
Patient's complaint in their own words, in quotes. Should establish that something has gone wrong, not routine post-op soreness.
Onset
When the complication symptoms started, expressed as days post-op (e.g., 'day 3 post-extraction').
Duration
How long the complication has been present (e.g., '48 hours,' 'since yesterday').
Severity 1-10
Pain or symptom severity rating; capture both peak and resting if they differ.
Tooth number(s)
Universal tooth number(s) or specific surgical site involved.
Findings
Clinical findings at the surgical site — empty socket, exposed bone, granulation tissue, suture status, dehiscence, fluctuance, sinus tract.
Swelling
Extraoral and intraoral swelling — location, extent, character (firm vs fluctuant), or 'none.'
Infection signs
Erythema, purulence, fluctuance, lymphadenopathy, fever, foul odor — or 'none consistent with infection.'
Bleeding
Active bleeding character, volume, response to pressure — or 'none.'
Dehiscence
Wound breakdown at flap, graft, or extraction site margins — location and extent — or 'not applicable.'
Dry socket
Empty socket with exposed bone, absent organized clot, foul odor — present or not applicable.
Nerve paresthesia
Numbness, tingling, or altered sensation in lip, tongue, chin, or other distribution — note distribution and patient testing if performed, or 'none.'
Other
Any additional clinical findings not captured above (oroantral communication, foreign-body reaction, retained root tip, etc.) or 'not applicable.'
Radiographs taken/reviewed and findings
Specific imaging captured today (with CDT codes), area imaged, and diagnostic-quality statement.
Diagnosis
Specific complication diagnosis with tooth/site (e.g., 'alveolar osteitis #30 day 4 post-D7140,' 'post-extraction wound dehiscence #4 graft margin').
Consent/PARQ reviewed; signed/verbally obtained
Consent process for today's intervention — risks, benefits, alternatives discussed, signed or verbal-with-witness, dated.
Anesthetic used
Anesthesia agent, concentration, vasoconstrictor, carpule count, technique — or 'topical only' or 'none required.'
Treatment rendered
Brief summary line of what was done today — sets up the procedure-specific detail below.
Irrigation/debridement/I&D/suture/dressing/medication application/other
Checklist of procedures performed at today's visit; each performed item must be detailed in the specific lines below.
Solution/amount or not applicable
Irrigation solution (saline, chlorhexidine, etc.), volume used, and technique. 'Not applicable' if no irrigation performed.
Debridement details or not applicable
Instruments used, character of debridement (gentle vs aggressive), tissue removed (granulation, sequestrum, food debris). 'Not applicable' if not performed.
I&D details or not applicable
Incision site and length, drainage character (purulent vs serosanguinous), volume drained, drain placement if used. 'Not applicable' if no I&D performed.
Suture details or not applicable
Suture type, count, location placed or removed. 'Not applicable' if no suture work performed.
Dressing placed or not applicable
Dressing material (eugenol paste, Alvogyl, iodoform gauze), placement technique, expected duration. 'Not applicable' if no dressing placed.
Medication applied or not applicable
Free-text field — fill in your clinical observations.
Prescription or none
Drug, dose, sig, quantity, refills for any prescriptions written today. 'None' with rationale if no Rx given.
None or describe
Complications encountered during today's intervention — bleeding, dressing dislodgment, patient tolerance issues — or 'none.'
Tolerance/response
Patient response to today's treatment — pain reduction achieved, vitals trend, dismissal status.
Instructions reviewed
Confirmation that post-op instructions were reviewed verbally and in writing.
Specific instructions
Complication-specific post-op guidance — dressing-loss instructions, dietary restrictions, return precautions, signs of worsening.
Return for re-evaluation
Scheduled re-evaluation date and purpose (e.g., 'dressing change in 3 days,' 'suture removal in 7 days').
Next visit
Scheduled or recommended next appointment with purpose and length.

Documentation requirements

D9930 is a by-report code — the narrative is the claim. Without it, the carrier cannot adjudicate and will deny. A defensible D9930 chart note must include:

Original procedure and date — the CDT code billed, tooth or site, and the date the original surgery was performed. This single line establishes whether you are inside or outside the global period and is the first thing an auditor checks. Example: "D7140 #30 performed 2026-04-18; patient returns today 2026-04-23."
Time elapsed since original procedure — explicitly state days post-op. Days 3-5 post-extraction is the classic dry-socket window; days 7+ with infection signs argues for delayed infection rather than dry socket.
Chief complaint in the patient's own words — quote it ("Pain started getting worse 3 days after the extraction; ibuprofen isn't touching it"). The complaint must establish that something has gone wrong, not that this is routine post-op soreness.
HPI specific to the complication — onset, character, severity (1-10), what triggers/relieves, what the patient has tried, presence of fever/swelling/bad taste/foul odor (classic dry socket descriptor), bleeding character if applicable.
Updated medical history and meds — anticoagulants and immunosuppression are particularly relevant to bleeding and infection complications. Note any new meds prescribed since the original procedure.
Vitals — BP and pulse. Required if any sedation, anesthesia, or surgical management is contemplated; also functions as a baseline if the patient is showing systemic symptoms (fever, tachycardia from infection).
Focused clinical exam of the surgical site — extraoral swelling/erythema/lymphadenopathy, intraoral soft-tissue findings, suture status, socket appearance (empty socket with exposed bone is the dry-socket pathognomonic finding), purulence, sinus tract, dehiscence, fluctuance, mobility of adjacent teeth/grafts.
Imaging if indicated — PA or pano if you suspect retained root tip, sequestrum, sinus involvement, or osteomyelitis. Bill the radiograph code separately (D0220, D0330) and document the interpretation in the chart note.
Specific diagnosis — name it: "alveolar osteitis (dry socket) #30," "post-extraction site infection #19 with localized cellulitis," "wound dehiscence at distal graft margin site #4," "persistent bleeding post-D7140 #14, etiology consistent with patient's enoxaparin therapy." Generic "post-op complication" is insufficient.
Procedures performed in detail — this is the heart of the by-report narrative:
- Irrigation — solution (saline, chlorhexidine 0.12%), volume, technique.
- Debridement — gentle vs aggressive, instruments used, granulation tissue or sequestrum removed.
- Incision and drainage — if performed, document the incision site and length, drainage character (purulent vs serosanguinous), volume drained, drain placement if used.
- Suture placement or removal — type, count, location.
- Dry-socket dressing — material (eugenol-based paste, Alvogyl, iodoform gauze), placement technique, expected duration in socket.
- Medication application — topical antibiotic, hemostatic agent (Surgicel, Gelfoam, tranexamic acid soak), other.
Anesthesia — if administered, document agent, concentration, vasoconstrictor, carpule count, technique. If no anesthesia was needed (typical for dry-socket dressing), note that.
Rx — analgesic plan (often a stronger NSAID regimen or a short opioid course for severe dry socket), antibiotics if infection is suspected/confirmed, chlorhexidine rinse. Drug, dose, sig, quantity, refills. Or "none" with rationale.
Why this exceeds routine post-op care — the explicit "by report" justification. State the unusual circumstance: "Dressing change and re-medication required; dry socket is not a routine sequela and required dedicated chair time outside the global period of D7140." This sentence is the difference between a paid D9930 and a denied one.
Patient tolerance and dismissal status — reaction to treatment, vitals trend if relevant, patient stable for dismissal.
Post-op instructions specific to the complication — return precautions, dressing-loss instructions for dry socket, signs of worsening infection, when to call.
Return for re-evaluation / next visit — most dry-socket cases need a dressing change in 24-72 hours; document the recall plan.
Provider signature and assistant initials.

Two pitfalls auditors flag immediately:

D9930 billed inside the global period without an unusual-circumstance narrative. The note describes routine post-op care that should have been bundled into the original surgery code; the carrier denies and the office is flagged.
Vague "treated complication" language with no procedural detail. Without specifics on irrigation, debridement, dressing, suturing, or medication application, the by-report code reads as a regular re-evaluation and is denied or recoded to D0140/D9110.

Common denial reasons

The most common reasons D9930 is denied, downgraded, or recouped:

Visit fell within the global period of the original surgery and no unusual-circumstance narrative was supplied. This is the dominant denial reason. Routine post-op care (suture removal, post-op check, "patient is healing well") is bundled into the original surgery fee; D9930 inside that window pays only when the chart explicitly establishes that what was done exceeded routine post-op care. Submitting D9930 without a date-of-original-procedure line, without the days-elapsed calculation, and without a narrative is an automatic denial at most carriers.
No by-report narrative attached to the claim. D9930 is by-report by ADA descriptor; claim forms without an accompanying narrative are denied at the front end. Many practice management systems require manually attaching the narrative — a templated D9930 chart note that lives only in the chart and not on the claim is a recurring failure point.
Vague narrative — "treated complication" without procedural detail. When the narrative does not name the diagnosis, describe the procedures performed (irrigation, debridement, dressing, I&D, re-suturing, medication), and explain why the encounter exceeded routine post-op care, the carrier denies for insufficient documentation. A one-line "patient seen for dry socket" narrative is rejected by most carriers.
More specific code applied. When the encounter is fully described by D7510 (intraoral I&D), D7511 (multiple-space I&D), D7910 (simple wound suturing), or D9110 (palliative pain treatment), carriers downgrade D9930 to the more specific code and pay accordingly. Using D9930 as a fallback for procedures that have their own descriptors is a common over-coding pattern.
Same-day overlap with D9110. D9110 (palliative) and D9930 (post-surgical complication) are treated as overlapping by virtually all carriers. Billing both on the same DOS for the same encounter results in one being denied as bundled.
Same-day-as-original-surgery billing. D9930 billed on the same DOS as the originating extraction or surgery is denied as bundled — same-visit complications are part of the original procedure code.
Original procedure performed by a different provider, no transfer-of-care documentation. Some carriers require evidence that the patient was originally treated elsewhere when D9930 is the first billed encounter; without it, the claim is denied as outside the practice's scope of care for that procedure.
Routine post-op pain or swelling without procedural intervention. Patients calling with normal post-op discomfort and being seen for reassurance and a Rx for ibuprofen does not qualify for D9930 — that is bundled or, if a focused exam was needed, D0140 + D9110 at most.
Templated narrative used identically across many patients. Auditors compare a sample of D9930 narratives; identical or near-identical text across multiple patients triggers a chart-review request and frequent recoupment.
Missing pre-op (originating surgery) chart documentation on appeal. When carriers ask for the original surgical chart note to confirm what was performed and when, missing or incomplete records lead to denial of the D9930 appeal.
Patient is not the practice's patient of record for the originating surgery and the narrative does not address why the complication is being managed at this office. A short line addressing this — "Patient was seen at our office for the original extraction on 2026-04-18 by Dr. X" or "Patient presents from another practice; original D7210 performed 2026-04-15 per outside records" — pre-empts the denial.
