Dermatology billing · Portland, OR
Dermatology medical billing services in Portland from 247MBS are tuned to a Pacific Northwest market anchored by OHSU academic dermatology, a strong medical-derm and biologics caseload, and Oregon's distinctive Coordinated Care Organization model for Medicaid.
Since 2005 you get a dedicated account manager, a free 360° dashboard, HIPAA plus SOC 2 Type II security, and coders who know the Oregon Health Plan CCO structure and the referral patterns that flow through Oregon Health & Science University.
Portland's dermatology profile leans more toward medical management than the Sun Belt's surgical concentration. Chronic inflammatory disease — psoriasis, atopic dermatitis, hidradenitis — is a large part of the caseload, and much of it now runs on buy-and-bill biologics that demand prior authorization, careful unit reconciliation, and a clear read on whether the drug bills through the medical or specialty-pharmacy benefit. Surgical dermatology, biopsies, destruction, and Mohs are certainly present, but a Portland practice typically balances that surgical work against a heavier medical and biologic book than a retiree-driven desert market would carry.
Oregon delivers most of its Medicaid through Coordinated Care Organizations — regional entities that manage the Oregon Health Plan for their members. For a dermatology claim, that means eligibility has to be verified with the correct CCO before the encounter, and the referral and authorization rules of that specific organization respected. OHSU's role as the region's academic referral hub also shapes the payer mix, drawing complex cases and a broad commercial and Medicaid population from across the metro. Get the CCO eligibility, the biologic authorization, and the covered-versus-cash line right, and Portland is a stable reimbursement market.
CPT, HCPCS, J-code, and modifier detail lives only inside this table so the surrounding prose stays readable.
| Service | Code range | Verified before submission | Oregon payer note |
|---|---|---|---|
| Office visit with same-day procedure | 99202–99215 + modifier 25 | Separately identifiable, documented evaluation | CCO and commercial edits scrutinize modifier 25 |
| Skin biopsy | 11102–11107 | Method plus per-additional-lesion add-ons | Frequency review on repeat sites |
| Excision — benign / malignant | 11400–11446 / 11600–11646 | Site, pre-excision diameter, margins; pathology before malignant final-code | Surgical work runs alongside medical |
| Destruction — AK / benign / malignant | 17000 / 17003 / 17004, 17110–17111, 17260–17286 | AK counts and frequency vs the LCD | Frequency validated against policy |
| Mohs micrographic surgery | 17311–17315 | Stages and blocks; no separate path same specimen; modifier 58 on staged closure | Prior auth on many plans |
| Dermatopathology | 88304 / 88305, 88312–88314 | Modifier 26 / TC split; in-house vs send-out | Sets technical-component billing |
| Biologics (buy-and-bill) | J-codes + 11900 / 11901 | Prior authorization, unit math, JW waste | Heavy medical-derm biologic book |
| Cosmetic (self-pay) | 64612 / J0585, fillers | ABN plus GA/GX/GY/GZ; collected before service | Never routed to a CCO as covered |
Because the caseload tilts medical, the leaks cluster around biologics and CCO rules, and this table is where recovery begins.

We provide dermatology practice billing throughout the metro — solo and independent dermatologists, group medical dermatology, surgical dermatology and Mohs micrographic surgeons, dermatopathology labs, pediatric dermatology, and hybrid cosmetic-plus-medical offices from close-in Portland and the Pearl to Beaverton, Hillsboro, Gresham, Lake Oswego, and across the river toward Vancouver. Whether you run a biologic-heavy medical-derm practice, a mixed surgical office, or a group credentialing a new provider, your claims are worked by coders who understand dermatology and Oregon's coordinated-care market.
Portland practices lose money less to their contracted rates than to biologic authorizations that slipped, CCO eligibility that was wrong, and denials no one has time to work. When you outsource dermatology billing in Portland to a specialty medical billing services company, biologic authorizations come before administration, CCO eligibility and referrals are confirmed before the visit, cosmetic and covered work are separated cleanly, and every denial is worked rather than written off. Our AAPC-credentialed coders treat medical derm, biologics, and Mohs as daily work.
We hold ourselves to a 99% first-pass clean-claim rate, up to 40% fewer denials, 90% of worked denials recovered, days in A/R under 25, and 98% client retention, all visible on your free 360° dashboard with a dedicated account manager owning the book. See our dermatology billing services overview and our Oregon medical billing page for the full scope, and we manage the prior authorization load that biologics and Medicare Advantage demand. A professional dermatology billing company built for the specialty keeps more of what a medical-derm practice earns.
Portland practices are billed out of the same Oregon desk. Statewide payer detail lives on the Oregon page.
Medical Billing for Dermatology — the codes, unit rules and denials nationally, without the local layer.
Yes. We verify eligibility with the member's Coordinated Care Organization before the visit, respect that CCO's referral and authorization rules, bill covered medical and surgical dermatology correctly, and keep cosmetic services off the ledger so Oregon's coordinated-care model does not create avoidable denials.
Yes. We obtain authorization before administration on buy-and-bill biologics, reconcile units and JW drug waste, and confirm whether the drug runs through the medical or specialty-pharmacy benefit, so a high-value biologic claim is not lost to a missing auth or a unit-math error.
We run biologic authorization on the medical side and the full surgical sequence — authorization, pre-excision measurement, pathology hold, and correct staging — on the surgical side, so both parts of a Portland practice clear billing at a first-pass clean-claim rate instead of generating appeals.
From solo practices to multi-provider groups, we bill Dermatology for Portland practices with a dedicated account manager, certified coders and a live dashboard — so the units, authorizations and appeals that decide your month stop being the thing nobody has time for.
