What dermatology billing looks like in San Diego
San Diego practices carry a high surgical share driven by decades of coastal sun exposure, with repeat Mohs patients who return for new primaries every year or two. That recurring surgical population makes accurate stage and repair coding a compounding revenue issue rather than a one-off.
The military and veteran population adds TRICARE and VA community-care claims to the mix. Both have their own authorization and filing rules, and a claim that would be routine under Medicare can fail entirely under community care if the referral is not attached correctly.
North County and border-adjacent practices also see more coverage discontinuity, so eligibility has to be verified close to the date of service rather than at scheduling.
The payers that decide your San Diego revenue
Noridian (Medicare Part B, Jurisdiction E)
Sets the surgical and destruction coverage rules for the region.
TRICARE West and VA community care
Referral and authorization documents must be attached at first submission or the claim fails outright.
Medi-Cal managed care
Plan assignment shifts, so eligibility is verified close to the visit rather than at booking.
Blue Shield of California and Anthem
Divergent edits on excision sizing and closure classification.
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, the same coverage articles as Los Angeles, applied to a market with heavier military-adjacent and TRICARE-secondary coordination.
- Medicaid program
- Medi-Cal managed care in San Diego County runs through Molina, Community Health Group, Health Net and Blue Shield Promise. Community Health Group's share is larger here than anywhere else in the state.
- Timely filing
- Medicare: 12 months. Medi-Cal: 6 months from the month of service. TRICARE: 1 year from date of service — the secondary claim is where practices lose it.
- Prompt-pay statute
- Health & Safety Code §1371 (45 working days, HMO) and Insurance Code §10123.13 (30 working days, PPO), with statutory interest for late clean claims.
Denials we see most in San Diego
- Community-care claims denied for missing or expired referral authorization.
- Mohs repairs billed where the closure did not meet the threshold for separate reporting.
- Destruction frequency limits exceeded on repeat actinic keratosis patients.
- Eligibility terminations discovered after the visit on Medi-Cal managed-care members.
The controls we run against them
- Referral and authorization validated and attached before any TRICARE or community-care claim is released.
- Repeat-patient frequency tracking per plan year so destruction limits are known before the visit, not after the denial.
- Repair classification checked against documented wound size and layer count.
- Eligibility verified 72 hours out and again on the day of service.

Frequently asked questions
Do you bill TRICARE and VA community care?
Yes. Both are handled with the referral and authorization documentation attached at first submission, which is where most community-care denials originate.
How do you keep repeat Mohs patients inside frequency limits?
Destruction and surgical frequency is tracked per patient per plan year, so the practice knows before the appointment whether the next service is payable and what documentation it needs.
Do you work with dermatopathology performed in-house?
Yes. Technical and professional components are split according to who performed which part, and the pathology charge is reconciled against the clinical charge before either is billed.
