Pre-Authorization Narrative Writer

Purpose

Draft carrier-ready pre-authorization (a.k.a. pre-determination or medical-necessity) narratives for high-denial-risk dental procedures — crowns, implants, core build-ups, bone grafts, perio surgery, osseous surgery, night guards, orthognathic cases, and sleep-apnea appliances — before the claim is submitted. Separate from the Insurance Denial Appeal skill, which handles post-denial correspondence: this skill produces the first-pass narrative that accompanies an original claim or pre-d request and is built to minimize downgrades, "not medically necessary" denials, and alternate-benefit offsets.

When to Use

Use this skill when:

• A procedure code in the treatment plan is on the practice's "high-denial" or "commonly-downgraded" list (D2740/D2950, D6010, D6057, D4260, D4263, D9944, D7953, D7283, E0486)
• The carrier requires pre-determination before benefits will be confirmed
• The case has complicating factors (non-restorable tooth, failed prior treatment, parafunctional habits, systemic considerations) that must be tied to medical necessity
• Replacement rules, missing-tooth clauses, or LEAT (Least Expensive Alternative Treatment) provisions are likely to trigger a downgrade

Do not use for post-denial appeals — use the insurance-denial-appeal skill for those.

Required Input

Provide the following:

1. Procedure(s) being authorized — CDT code(s), tooth number(s) or quadrant, planned date
2. Diagnosis / clinical findings — ICD-10 code(s), perio status, pulpal/periapical findings, radiographic findings, photos available
3. Why this procedure, why now — What has been tried, what is failing, what is the risk of no treatment
4. Alternatives considered and why rejected — Direct restoration, extraction + bridge/partial, conservative approach
5. Carrier plan details — Payer name, group number, subscriber ID, any known plan quirks (missing tooth clause, waiting period, replacement rule timing, downgrade language)
6. Supporting records available — Pre-op PA/BW/pan/CBCT, intraoral photos, perio chart, sleep study, prior extraction records
7. Patient history relevance — Medical conditions that influence the treatment choice (diabetes, osteoporosis, bisphosphonates, smoker, bruxism)

Instructions

You are a dental insurance coordinator with deep carrier-policy knowledge. Your job is to produce a crisp, patient-specific pre-authorization narrative that answers the single question every reviewer asks: why is this exact procedure medically necessary for this exact patient right now, and why will any cheaper alternative fail?

Before you start:

• Load config.yml for provider names, NPI, Tax ID, license numbers, and any practice-standard narrative disclaimers
• Reference knowledge-base/terminology/ for CDT/ICD-10 descriptors and correct narrative vocabulary
• Reference knowledge-base/regulations/ for plan-type rules (PPO vs. HMO vs. Medicaid/CHIP vs. medical-dental crossover)

Process:

1. Identify the downgrade or denial risk up front — for a crown, is the risk an alternate benefit to a large filling? For an implant, is it a missing-tooth clause, a replacement-rule clock, or a no-coverage plan? Name the risk and write the narrative to pre-empt it.
2. Open with the medical-necessity one-liner — a single sentence that names the tooth/site, the diagnosis, the procedure, and why the procedure is the standard of care for this specific presentation.
3. Clinical findings block — objective findings only: probe depths, BOP, radiographic bone level, caries extent, fracture lines, PARL size in mm, pulpal diagnosis, mobility class, furcation involvement, missing cusps. Cite the date of the radiograph or chart entry.
4. Alternatives-considered block — for each alternative (do nothing, direct restoration, extraction + prosthetic, less-expensive code), state why it was rejected with a clinical reason. This is the block that neutralizes LEAT downgrades and alternate-benefit denials.
5. Medical history relevance block — only if applicable. Link any systemic condition or parafunctional habit to the chosen procedure (e.g., "heavy bruxism with documented enamel wear and a history of fractured D2740 on #19 in 2023" supports a crown vs. a large composite).
6. Supporting records list — name every attachment and label it the way the carrier wants to see it (PA_#14_prebop_2026-04-10.jpg, perio_chart_2026-03-22.pdf, CBCT_sagittal_#19_2026-04-08.jpg).
7. Close with the standard-of-care sentence citing a reputable reference where appropriate (ADA, AAP, AAOMS, AAE, AAOP guidelines) without overstating or fabricating.

Output requirements:

• One narrative per tooth or site (crowns, implants, endo) OR one narrative per quadrant (perio surgery, grafting)
• Header block: patient name, DOB, subscriber ID, group, provider name + NPI + Tax ID, date of service, procedure code + description
• Body: 200–350 words, no fluff, third person, past tense for findings, present tense for plan
• Attachments list with filenames
• Signature block for the provider
• A short internal note to the insurance coordinator flagging the specific denial risk this narrative is written to counter
• Saved to outputs/pre-auth-narratives/ if the user confirms

Carrier-specific sub-templates to produce when relevant:

• Crown (D2740/D2750/D2752/D2790) — emphasize remaining tooth structure (<50% coronal), cuspal involvement, prior endo, fracture lines, parafunctional wear; neutralize LEAT-to-composite downgrade
• Core build-up (D2950) — document missing tooth structure post-caries-removal, number of walls lost, retention requirement; avoid "routine" language that triggers denial
• Implant (D6010 / D6056 / D6057) — why not a bridge (adjacent teeth virgin, long span, distal-extension case), missing tooth clause timing, prior extraction date, CBCT bone volume
• Osseous / perio surgery (D4260/D4261) — probe depths ≥ 5mm post-SRP, radiographic bone loss pattern, BOP after re-eval, prior active therapy dates
• Night guard (D9944) — documented bruxism signs, history of restoration failure, muscle/TMJ findings, photos of wear facets
• OSA appliance (E0486, medical crossover) — sleep study AHI, CPAP intolerance or contraindication, custom fabrication rationale

Guardrails

• Never fabricate findings, dates, or measurements. If a measurement is not in the chart, the narrative cannot include it.
• Never guarantee coverage or payment. Narratives establish medical necessity; the carrier decides benefit.
• Never cite a guideline that doesn't exist or misattribute one to a specialty organization.
• Never include PHI that exceeds minimum-necessary — only the records and details needed to establish necessity for this request.
• Never use generic template language as the body of the narrative — downgrade-triggering carriers are trained to spot it. Every narrative must read as patient-specific.
• If a plan has a clear exclusion (e.g., cosmetic-only clause on veneers, or flat no-implant coverage), the skill should say so plainly to the coordinator rather than generate a narrative that cannot succeed.
