What dermatology billing looks like in Los Angeles
Los Angeles dermatology mixes medical and aesthetic work more heavily than almost any other market. A single appointment can contain a cosmetic service the patient pays for and a medical service the plan pays for, and if those two are not separated cleanly at the point of charge capture, the practice either bills the plan for something it will never cover or writes off medical work as cosmetic.
Medi-Cal in Los Angeles County is administered through managed-care plans rather than fee-for-service, so the claim has to reach the right delegated entity. Sending it to the wrong one produces a denial that looks like a coverage problem but is actually a routing problem.
Group practices here also carry a heavy commercial contract load, and contracted rates vary enough between plans that underpayments hide easily unless every payment is reconciled line by line against the contracted fee schedule.
The payers that decide your Los Angeles revenue
Noridian (Medicare Part B, Jurisdiction E)
Governs the Part B surgical and destruction rules for the whole state.
Medi-Cal managed care
Delegated to plan and IPA level in Los Angeles County, so claims must route to the correct delegated entity.
Anthem Blue Cross and Blue Shield of California
Two separate Blues plans in one market, each with its own edits and fee schedule.
Health Net, Kaiser referrals and IPA arrangements
Referral and authorization chains must be intact before the visit is billable.
California rules that change how your claims are filed
Coverage policy, filing windows and payment deadlines are set at state and contractor level. These are the California specifics we bill against. Payer policy changes, so confirm the current version before citing one in an appeal.
- Medicare coverage policy
- Noridian Jurisdiction E governs California. Benign lesion removal, actinic keratosis destruction and Mohs indications are all controlled by MAC coverage articles rather than national policy, so documentation is written to the local language.
- Medicaid program
- Medi-Cal, largely through managed care: L.A. Care, Health Net, Molina Healthcare and Blue Shield Promise in Los Angeles County. Each delegates utilization management differently, which is why one plan authorizes a procedure another denies.
- Timely filing
- Medicare: 12 months. Medi-Cal: 6 months from the month of service, with limited late-claim exceptions. Commercial HMO products in California commonly run 90 days.
- Prompt-pay statute
- Health & Safety Code §1371 requires HMO clean claims to be reimbursed within 45 working days; Insurance Code §10123.13 sets 30 working days for insurer PPO claims, plus interest on late payment.
Denials we see most in Los Angeles
- Medical services denied as cosmetic because the documentation did not establish medical necessity separately from the aesthetic service performed the same day.
- Medi-Cal claims rejected for wrong-entity submission when the member sits under a delegated IPA.
- Modifier 25 downcoding on visits where a procedure was performed the same day.
- Silent underpayments against contracted rates on excisions and repairs.
The controls we run against them
- Split-encounter workflow that separates the self-pay cosmetic charge from the billable medical charge at the point of capture.
- Medi-Cal routing table maintained at plan and IPA level, refreshed monthly.
- Modifier 25 documentation test applied before submission, with a standing appeal pipeline for downcodes.
- Line-by-line payment reconciliation against each contracted fee schedule, with underpayments recovered rather than posted.

Frequently asked questions
How do you separate cosmetic and medical charges on the same visit?
The cosmetic service is captured as a self-pay charge with its own consent and pricing, and the medical service is coded and billed only where the documentation independently supports medical necessity. The two never share a claim line.
Do you handle Medi-Cal managed care and IPA-delegated claims?
Yes. We maintain a routing table at plan and delegated-entity level for Los Angeles County and verify delegation before submission, which removes most of the rejections practices read as coverage denials.
Can you recover underpayments on our commercial contracts?
Every payment is reconciled against the contracted rate for that CPT code and payer. Variances are queued for recovery rather than written off at posting.
