Why it happens in Long Beach derm
High same-day E&M-plus-procedure volume
How 247MBS prevents it
Note review confirms a distinct, separately identifiable E&M
Dermatology billing · Long Beach, CA
Dermatology medical billing services in Long Beach from 247MBS give South Bay skin practices a revenue cycle built for a diverse, mixed-payer coastal market — the medical, surgical, and pathology work that keeps a derm schedule moving.
Since 2005 you get a dedicated account manager, a free 360° dashboard, HIPAA plus SOC 2 Type II security, and coders fluent in both Molina Medi-Cal managed care and a deep commercial book.
Most Long Beach derm revenue does not disappear at the fee schedule — it disappears at the edit. The table below is where a South Bay practice actually leaks money, and it is the first thing we lock down when a new account comes aboard.

| Service line | Codes we work | Checked before submission | Long Beach payer note |
|---|---|---|---|
| Same-day E&M with a procedure | 99202–99215 + modifier 25 | Separately identifiable, documented E&M distinct from the procedure | Molina and commercial edits scrutinize mod 25 |
| Skin biopsy | 11102–11107 | Method plus per-additional-lesion add-ons | Medicare and PPO frequency edits |
| Benign vs malignant excision | 11400–11446 / 11600–11646 | Site, diameter, margins measured before excision; path confirmed pre-final-code | Rework driver if coded pre-path |
| Lesion destruction / actinic keratosis | 17000 / 17003 / 17004, 17110–17111, 17260–17286 | Lesion counts and frequency against the LCD | AK counts drive Medicare denials |
| Mohs micrographic surgery | 17311–17315 | Stages and blocks; no separate path on the same specimen; modifier 58 on staged closure | MA prior auth common |

Long Beach is one of the most demographically diverse cities in the country, and that diversity runs straight through the payer mix. A practice off Atlantic Avenue or in Belmont Shore can see a commercially insured professional, a Molina or other Medi-Cal managed-care member, and a Medicare patient in for skin-cancer surgery inside the same morning — three different rulebooks on one schedule. MemorialCare's Long Beach Medical Center anchors the region's hospital and referral network, feeding surgical and pathology work into local derm offices, and Los Angeles County's Medi-Cal plans cover medical and surgical dermatology while holding firm cosmetic exclusions.
That mix rewards a specialty revenue cycle and punishes a generalist. Medi-Cal managed care demands eligibility and benefit checks before the visit and codes medical and surgical dermatology to plan-specific rules; the commercial book scrutinizes modifier 25 on every same-day service; and a Medicare skin-cancer population turns destruction, excision, and Mohs into a documentation exercise where a missing margin or lesion count is a denial. A dermatology billing company that treats a Long Beach schedule as one flat claim stream loses revenue in every payer lane. We route each service to the rule that governs it, so covered medical and surgical work is paid the first time and cosmetic dollars are collected up front rather than chased.
Revenue review
A certified dermatology billing specialist reviews your coding, unit counts, authorizations and aged A/R against the payers you actually bill in Long Beach, CA — and puts a number on what your current process is leaving on the table.

The dermatologists who outsource to us want a clean first-pass claim, not the lowest invoice. When you outsource dermatology billing in Long Beach to a specialty medical billing services company, modifier 25 stops being a coin flip, malignant excisions wait for pathology before they final-code, and biologic prior authorizations for psoriasis and atopic-dermatitis drugs are secured before administration rather than appealed after a denial. Our AAPC-credentialed coders read derm notes daily, so a separately identifiable service reads as separate on the claim.
The proof is in the numbers 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. You keep full visibility through the free 360° dashboard, and a dedicated account manager owns your book rather than a rotating queue. For the full picture of this professional service, see our dermatology billing services hub and our California medical billing page, and we handle the credentialing that adding a provider requires. A dermatology billing company that specializes beats a generalist that dabbles.
We bill for solo and independent dermatologists, group medical dermatology practices, surgical dermatology and Mohs micrographic surgeons, dermatopathology labs, and hybrid cosmetic-plus-medical offices from Bixby Knolls and Belmont Shore to Signal Hill, Lakewood, and Seal Beach. Whether you are a single-provider office bringing on an associate who needs credentialing or a multi-location group taking referrals from the region's hospital network, your claims are handled by coders who work dermatology every day, not a general pool. Long Beach's diverse patient base means a heavy load of medically necessary conditions across a wide range of skin types — from severe acne and inflammatory disease that qualifies for biologics to pigmentary disorders that never touch a cosmetic code — and each service line is worked to its own documentation and coverage rules.
Medical billing for dermatology in Long Beach turns a three-rulebook schedule into first-pass payment — a commercially insured professional, a Molina Medi-Cal member, and a Medicare skin-cancer patient can share one South Bay morning. 247MBS routes each service to the rule that governs it, verifies Los Angeles County Medi-Cal eligibility before the visit, holds malignant codes until pathology confirms, and captures the pre-excision measurement every payer wants. Our AAPC-credentialed coders work the MemorialCare Long Beach Medical Center referral stream and read derm notes daily. The result is covered medical and surgical work paid the first time and cosmetic dollars collected up front, backed by a 99% first-pass clean-claim rate and days in A/R under 25.

Long Beach practices are billed out of the same California desk. Statewide payer detail lives on the California page.
Dermatology Billing Services — the codes, unit rules and denials nationally, without the local layer.
We verify eligibility and benefits with Molina Healthcare and the other Los Angeles County Medi-Cal plans before the visit, confirm covered versus cosmetic, and code medical and surgical dermatology to each plan's rules so covered work is not denied as non-covered.
Yes. We keep the two ledgers separate, collect the cosmetic portion up front with a proper ABN, and route only covered medical and surgical services to the payer — exactly where hybrid coastal practices leak revenue.
Yes. We bill Mohs stages correctly without double-billing pathology on the same specimen, apply the modifier 26 / TC split by whether your lab reads in-house or sends out, and manage the global period on staged closures so the next-day repair is not swallowed as bundled.
We begin on your open A/R the week we onboard, work aged and denied claims alongside new submissions, and hold a professional standard of days in A/R under 25 once the backlog clears.
From solo practices to multi-provider groups, we bill Dermatology for Long Beach 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.
