The official code, for the date you are coding.

Capabilities

Six tools available now, each answering for one edition on one date.

Encoder

Open any ICD-10-CM code on a date. Read its full title, whether it is billable, the notes it inherits from every level above it, and its CMS-HCC V28 mapping with the factor for each segment. With nothing typed yet, the Encoder opens on a centred search box with example chips to start from.

Code Book

Browse the Tabular List for the edition in force on your date: chapters, then sections, then categories, then codes. Headers that need more characters are marked apart from valid codes, each code opens its card, and every card has a Show in Code Book link back to its place in the tree.

Cheat Sheet

A printable one-pager for the date you give: the V28 payment HCCs with their labels and the community, non-dual, aged factors, the HCC hierarchies, how a code is built, and MEAT (an industry convention, not CMS guidance). Filter it, or press Print.

Search and spelling

Type words instead of a code. Buddy searches that edition's Alphabetic Index and Tabular titles, and offers the right spelling when a word is off.

Evidence / MEAT

Paste a short sentence without identifiers and pick a code. Buddy marks where the condition is written, whether it is affirmed, denied or family history, and the Monitor, Evaluate, Assess and Treat words around it. The text is checked and discarded.

RAF calculator

Enter age, sex, entitlement and diagnoses to see the raw V28 score, each factor in it, and the line of CMS's own software behind every step. No name or member ID is asked for.

Try it

Open any of these to see a capability at work. You will be asked to sign in first, then taken straight there.

More examples, and what each answer means, are in Help.

Principles

A reference is only useful if you can check it. These rules hold on every screen.

• Every figure has a source

  Titles, notes, HCCs and factors are read from official CDC and CMS files, each recorded with its checksum. Click a figure to see the file. If a file is missing, Buddy says which one instead of guessing.

• One edition at a time

  Answers are for the edition in force on the date you give. When no edition covers that date, Buddy refuses and names what is missing. It never borrows a neighbouring year.

• No HCC is not the same as invalid

  A valid code with no HCC, a code newer than the mapping file, and a code that does not exist are three different answers. Buddy keeps them apart.

• It informs, you decide

  Buddy never approves a code, never turns a suspected condition into a diagnosis, and never proposes a code from a medication.

• No patient data

  Buddy holds no charts. Text you paste into the evidence check is not stored and is sent to no AI model.

• No CPT content

  CPT is licensed by the AMA. Until a licence is in place the CPT screen is locked, and it has a button to tell us you need it.
