A “West Hills Pat PPD” charge on your bank statement is an ACH debit from West Hills Pathology Consultants, a physician-led pathology group in West Hills, California. “Pat” is short for pathology, and “PPD” (Prearranged Payment and Deposit) means the money was pulled electronically from your checking or savings account rather than run on a credit card. The charge usually follows lab work, a biopsy, or a surgical procedure at the facility the group serves, even if you never spoke to a pathologist directly.
Where the Charge Comes From
West Hills Pathology Consultants is located at 7300 Medical Center Drive in West Hills, California, and specializes in anatomic and clinical pathology: microscopic examination of tissue, cells, and body fluids, plus clinical lab testing.1NPI DB. West Hills Pathology Consultants NPI Profile That address is the former West Hills Hospital and Medical Center, acquired by UCLA Health from HCA Healthcare in March 2024 and renamed UCLA West Valley Medical Center.2UCLA Newsroom. UCLA Health Acquires West Hills Hospital and Medical Center
When you have surgery, a biopsy, or lab work at a hospital, the pathology group that analyzes your specimens is often a separate practice that contracts with the facility. They bill independently of the hospital and of your treating physician. That’s why a single visit can produce more than one charge, and why one of them may come from a name you don’t recognize.
Why It Shows Up as an ACH Debit
The “PPD” tag identifies the transaction as a Prearranged Payment and Deposit entry, the standard ACH classification for consumer-account transactions.3Modern Treasury. PPD SEC Code For a PPD debit to run, you (or someone on the account) must have provided written or similarly authenticated authorization at some point. In medical settings, that authorization is often part of admissions paperwork or a payment agreement signed before a procedure.
Because this is an ACH debit rather than a credit card charge, the rules for disputing it are different. That matters for what you do next.
Check Whether the Charge Is Actually Wrong
A charge from West Hills Pathology Consultants isn’t automatically an error. If you or anyone on your account recently had blood work, a biopsy, a surgical procedure, or any hospital visit at the former West Hills Hospital (now UCLA West Valley Medical Center), a separate pathology bill is a normal part of medical billing.
Before disputing, the CFPB recommends requesting an itemized bill from the billing office listed on your statement, checking whether your insurance has already paid, and confirming the charge isn’t a duplicate.4Consumer Financial Protection Bureau. What Should I Do If I Can’t Pay a Medical Bill If it turns out the pathologist was out of network at an in-network facility, don’t just dispute with the bank; the surprise-billing rules below likely apply.
Disputing the Charge With Your Bank
ACH debits are covered by the Electronic Fund Transfer Act and Regulation E. Notify your bank, orally or in writing, within 60 days of the statement date on which the charge first appeared. The bank must investigate. It cannot make you file a police report, get a notarized affidavit, or contact the merchant first before it starts.5Consumer Financial Protection Bureau. Electronic Fund Transfers FAQs
The bank generally has 10 business days to finish. If it needs longer, it can take up to 45 calendar days, but it has to put a provisional credit for the disputed amount back in your account within those first 10 business days.6Consumer Financial Protection Bureau. Regulation E Section 1005.11 If the bank finds the transfer was unauthorized, it must correct the error within one business day. The burden of proof is on the bank to show the charge was properly authorized, not on you to prove it wasn’t.7Consumer Compliance Outlook. Error Resolution and Liability Limitations Under Regulations E and Z
If the charge is real but the amount or timing doesn’t match what you authorized, the bank can return the entry using NACHA’s R11 code, which covers debits that don’t line up with the terms of the original authorization.8Nacha. Differentiating Unauthorized Return Reasons
If the Charge Hit a Credit Card Instead
If the pathology charge appeared on a credit card, the Fair Credit Billing Act applies. Send a written dispute letter to the card issuer’s billing inquiry address within 60 days of the statement date.9Federal Trade Commission. Using Credit Cards and Disputing Charges Include your name, account number, and a description of the disputed charge. Certified mail with return receipt is sensible. The issuer must acknowledge the dispute in writing within 30 days and resolve it within 90 days.10Fairfax County. Understanding the Fair Credit Billing Act Federal liability for unauthorized credit card charges is capped at $50, and many issuers waive it.
Surprise Billing Protections for Pathology
Pathology is one of the specialties most affected by surprise billing, because patients rarely choose the pathologist. Tissue is sent to whichever lab the hospital uses. Two laws limit what an out-of-network pathologist can charge you.
The No Surprises Act
Effective January 1, 2022, the federal No Surprises Act prohibits out-of-network providers from balance billing patients for ancillary services, a category that explicitly includes pathology, when those services are delivered at an in-network facility.11U.S. Department of Labor. Avoid Surprise Healthcare Expenses Your cost-sharing (deductible, copay, or coinsurance) has to be calculated at the in-network rate no matter what the pathologist’s network status is.12Consumer Financial Protection Bureau. What Is a Surprise Medical Bill Providers can’t ask you to waive those protections for ancillary services like pathology, even outside emergencies.
If a bill exceeds what your Explanation of Benefits shows for cost-sharing, call the No Surprises Help Desk at 1-800-985-3059 or file a complaint online through CMS.13CMS. No Surprises: Understand Your Rights Against Surprise Medical Bills If you’re uninsured or paying out of pocket, you’re entitled to a good faith estimate before care, and you can dispute a final bill that exceeds it by $400 or more within 120 days.12Consumer Financial Protection Bureau.

California’s AB 72
California had its own protections in place before the federal law. AB 72, effective July 1, 2017, bars out-of-network providers from billing patients more than in-network cost-sharing when the patient used an in-network facility, including laboratories, and did not consent in advance to out-of-network care. Any consent to out-of-network billing has to be given in writing at least 24 hours ahead of the service, on a separate document, with a written cost estimate. Under AB 72, a disputed surprise bill can’t be used to damage your credit, garnish wages, or put a lien on your home.14California Department of Insurance. No Surprise Bills
AB 72 applies to commercial insurance plans regulated by the California Department of Insurance or the Department of Managed Health Care. It does not cover Medi-Cal, Medicare, or self-insured employer plans.14California Department of Insurance. No Surprise Bills For patients in those categories, the federal No Surprises Act covers emergency services and ancillary services at in-network facilities.
